October 24, 2025 Geoscience Community: We greatly appreciate every Summit Sponsor and Event Sponsor who contributed to RMAG over the last year. Your support is essential to our organization.

In 2025, the Rocky Mountain Association of Geologists was proud to host a dynamic lineup of events, including the North American Helium & Hydrogen conference, which examined the quickly growing field. Members explored the beauty and geological wonders of the Grand Canyon and the San Jaun’s as well geology across the state. Volunteers shared their passion for geoscience with students across the region through classroom visits and community festivals. Members also enjoyed numerous opportunities to connect outside the office through monthly lunches, coffees, happy hours, and our annual Golf Tournament.

Looking ahead, 2026 brings new opportunities for RMAG and our partners. Your financial support allows us to start the year off with a luncheon on the State of the Industry before diving into the impacts of new and evolving technologies on industry including in AI’s ever-growing presence. Plans are coming together to host a fundamentals class series throughout the year, two separate symposiums on the research out of USGS and research on the Mowry. Networking in 2026 will include our regular happy hours and coffee hour networking, plus we’ll have Rockbusters, the Golf Tournament and we’re bringing back the Clay Shoot. With your support RMAG Members share the wonders of earth sciences through community and school outreach. Finally, your financial support is crucial to our publication efforts, which include the monthly Outcrop newsletter and the quarterly Mountain Geologist journal.

Your financial commitment includes enrollment opportunities across all the RMAG events, whether joining the educational opportunities and joining the comradery of the golf tournament your employees will gain access.

students and geologists at any stage in their career.

The Membership Committee reports that Coffee and Happy Hour will return in January and are working on planning events such as The Rockbuster’s Ball (January 30th), Clay Shoot (May 8th), and Golf Tournament (late August) as well as spring and summer social events. The Publications Committee will have a new link for Member’s Corner submissions streamlining the process and The Outcrop has a solid pipeline of articles through early Spring. The Winter edition of The Mountain Geologist should be released by the end of the year. The On the Rocks Committee is at no shortage of ideas for our 2026 field season and some trips, such as the Yampa/Green River float trip have already been sold out.

Lastly, some new business, our YouTube Channel (@RMAGDenver) has launched, showcasing Luncheon talks and other videos that are at least a year old. More recent talks can still be bought on the RMAG site. This is a great addition to our media portfolio providing a great resource for teachers, students and interested parties to learn more about geology, while creating some nominal revenue for the organization in the process. The board also voted during the meeting to approve the 2026 budget, and Bridget’s compensation package.

This will be my last Secretary’s note as my 2-year term has ended this month. Not to worry, you all will be in great hands with our new Secretary, Stephanie, who will take over starting on next month’s issue.

Thank you to all who have made my time at RMAG such an enjoyable experience, especially Bridget and the Board members. I am planning on remaining an active member following this post and will be back to contributing to the Continuing Education Committee. Hope you all have a happy holiday and a great new year!

The Board of Directors met on December 12th, 2025, in-person at the Denver Earth Resources Library at 3pm. All current board members were present except for one. We also had two of our 2026 new board members join us for the meeting. The office began with reporting membership numbers. Notably we crossed the 1200 active member threshold which is a great milestone and added 20 new members this month. Attendance for our end of year events was as expected for this time of the year.

The Finance Committee reported a net revenue of -$8.1k, which is to be expected around the end of the year. This past month the Finance Committee executed on our new investment policy which includes a slightly more conservative portfolio of assets as well as operating expenses held in liquid/cash assets. At the meeting the board voted to approve new investment policy language in our governing documents. The CEC committee reported that Luncheon attendance was good despite the weather and has talks organized through March of next year. They are working on planning a USGS Symposium in the Spring for papers and posters that did not get presented at the RMS-AAPG event in the Fall due to the Government shutdown, and are planning a Basin Conference focusing on the Mowry for next fall, with a call for papers to come out in a couple of months. They will also organize a series of 101 classes with topics including Data Science and Analytics, Geosteering, Reservoir Engineering, Economics, Geothermal and more, relevant to both

PRESIDENT’S LETTER

By Sandra Labrum slabrum@slb.com

A Year of Connections First of all, Happy New Year! I am so thrilled to be writing to you in 2026. I like to begin each new year by taking stock of what mattered most in the year behind us and by setting an intention for the year ahead, even if that focus devolves as the year unfolds.

In that spirit, I want to start by thanking our outgoing Board members for their time, passion, and commitment to RMAG. I know you’ve heard it a hundred times, but it truly bears repeating: RMAG would not be the society it is without dedicated volunteers who are willing to step up and serve. Your contributions make a real and lasting impact.

OUTCROP | January 2026

I would also like to extend my heartfelt thanks to our incredible Executive Director, Bridget. Your leadership, organization, and vision have elevated RMAG and made us the envy of many professional societies.

We are incredibly fortunate to have you.

As we look ahead, I would love for 2026 to be a year of continued growth for RMAG. Over the past several years, we have settled into a pattern of thoughtful diversification, and I am excited to see that momentum continue. We have expanded our technical programming to better serve not only the oil and gas community, but also the broad and evolving range of geologic interests represented in our membership. We have embraced new technology with the launch of the RMAG YouTube Channel (check it out if you haven’t yet @RMAGDenver it’s a fantastic resource). And this year, we are offering a diverse slate of field trips that I hope will spark curiosity and engagement across our community.

Most of all, I hope we can make 2026 a year of new connections. I encourage you to attend an event you haven’t been to before, volunteer for a committee (please, please, please!), or consider signing up to give a lunch talk. My goal is to leave my term as RMAG President having helped foster a stronger, more connected society.

There’s a saying that goes: If you want to go fast, go alone. If you want to go far, go together. Let’s see just how far we can go together with RMAG in 2026.

Warm regards and Happy New Year, —Sandra Labrum

LEAD STORY

FROM OUTCROPS TO OCEANS PART 1

A ROCKY MOUNTAIN GEOLOGIST’S GUIDE TO GOING TO SEA

BY CODY BAHLAU cbahlau@ldeo.columbia.edu

experience aboard the R/V Marcus G. Langseth. Operated by Columbia University’s Lamont-Doherty Earth Observatory (LDEO) and supported by the U.S. National Science Foundation, the Langseth carries forward a proud legacy of ocean exploration. Its predecessors, including the R/V Vema, R/V Robert D. Conrad, and R/V Maurice Ewing, played pivotal roles in defining modern marine geology. These ships supported decades of transformative science, from seafloor spreading confirmation to global bathymetric mapping.

The legacy includes figures such as Marie Tharp, who worked at Lamont and co-created the first comprehensive maps of the ocean floor. Her work revealed the Mid-Atlantic Ridge and transformed our understanding of plate tectonics.

Originally built in 1991 for the oil and gas industry and refitted for academic research in 2008, the R/V Marcus G. Langseth is a global-class research

INTRODUCTION Fieldwork often conjures images of outcrops, rock hammers, and rugged terrain, but some of the most valuable geologic data lies hidden beneath the sea. For geologists accustomed to the Rockies, fieldwork typically means direct observation of exposed structure. Offshore, the landscape is submerged, and data is gathered through remote sensing, acoustic imaging, and sampling tools. Yet the scientific goals remain strikingly similar: mapping structure, interpreting stratigraphy, and reconstructing tectonic history.

This article is the first in a two-part series designed to help geoscientists navigate the transition from land to sea. Here, the focus is on preparation, logistics, and daily life aboard a research vessel. A follow-up article will take a deeper dive into the geophysical tools, data collection techniques, and technology that power offshore exploration.

The guidance provided draws from firsthand

LEAD STORY Foundation (NSF). Proposals must align with a program’s scientific priorities and follow the guidelines in the NSF Proposal and Award Policies and Procedures Guide (PAPPG). This includes sections on intellectual merit, broader impacts, and a detailed data management plan. Proposals are submitted through Research.gov or Grants.gov, and institutional registrations must be completed in advance.

Principal Investigators (PIs) are most often university faculty, research scientists at nonprofit institutions, or staff scientists at national laboratories. In some cases, postdoctoral researchers may serve as PIs, depending on the requirements of the specific NSF program. Regardless of background, all PIs must be affiliated with an eligible U.S.-based institution that can receive federal research funding.

For those new to oceanographic fieldwork or unfamiliar with requesting ship time, the NSF–UNOLS Chief Scientist Training Cruise Program offers a valuable introduction. This multi-day cruise, along with pre- and post-cruise workshops, guides early-career marine scientists, such as PhD students and postdocs, through the process of planning, executing, and leading shipboard research aboard a UNOLS vessel. The program also covers how to request research time for specialized equipment like ROVs and submersibles.

Participants often receive stipends to help with travel and research costs, making it a practical and educational first step toward becoming a Chief Scientist.

Once funded, PIs work closely with the University-National Oceanographic Laboratory System (UNOLS) and vessel operators to determine the feasibility of their proposed work, coordinate cruise logistics, and ensure compliance with permitting and data archiving requirements. Successful PIs are responsible not only for meeting the scientific goals of the cruise but also for mentoring early-career participants and ensuring that data are properly archived through programs such as Rolling Deck to Repository (R2R).

vessel specializing in marine geophysics. Its capabilities include 2D and 3D multichannel seismic acquisition, multibeam bathymetry, sub-bottom profiling, sediment coring, dredging, and deployment of ocean bottom seismometers. From the Arctic to the Southern Ocean, it supports international collaboration that explores plate boundaries, rift zones, and geologic hazards. Since joining the academic fleet, the Langseth has sailed more than 700,000 kilometers in pursuit of ocean science.

The author, Cody Bahlau, serves as Chief Science Officer aboard the Langseth and has participated in over 30 oceanographic expeditions worldwide. With a background in geology, a graduate certificate in GIS, and prior experience in the oil and gas sector, he manages shipboard operations, coordinates technical teams, and bridges communication between scientists, crew, and shore-based institutions. His work spans seismic surveys, coring campaigns, and public outreach, including livestreams that connect offshore science with classrooms across North America.

I. GETTING INVOLVED IN OFFSHORE RESEARCH:

Offshore research is inherently collaborative, drawing together scientists, students, and technical professionals from across the U.S. and beyond. These teams not only work together but often live together for weeks or months at sea. Institutions such as Lamont-Doherty Earth Observatory (LDEO), Woods Hole Oceanographic Institution (WHOI), Scripps Institution of Oceanography, and the University of Texas Institute for Geophysics (UTIG) regularly lead or contribute to expeditions aboard the Langseth and other research vessels.

Opportunities to sail aboard research ships are open to a wide range of participants, including principal investigators, graduate and undergraduate students, technical staff, and outreach specialists. These roles exist not only within the U.S. academic fleet but also through federal agencies and private foundations. Each path has its own entry points, requirements, and expectations.

LEAD STORY

Technical Professionals Technicians play a critical role in every offshore expedition, supporting the operation, deployment, and maintenance of complex instruments and systems. Their work spans multiple disciplines, including electronics, data engineering, sonar operations, mechanical systems, deck equipment handling and Vol. 75, No. 1 | www.rmag.org

Students and Early-Career Scientists Graduate and undergraduate students often join research cruises as part of a PI’s science team, contributing to data collection, instrumentation, and sampling. These shipboard experiences offer valuable exposure to multidisciplinary science, technical workflows, and collaborative research in a remote setting. Many participants are recruited directly through university departments and research labs, where PIs advertise open berths via email lists, bulletin boards, or faculty networks. Opportunities are also shared through national platforms such as the UNOLS Opportunities page and the UNOLS Early Career Programs page, which highlight internships, training cruises, and open calls for cruise participation.

Several structured programs support student engagement: • STEMSEAS (STEM Student Experiences Aboard Ships) offers short-term exploratory cruises for undergraduates, particularly those from underrepresented backgrounds or with limited prior field experience.

• NSF-supported programs, such as the OCE Postdoctoral Research Fellowships and other awards, may include cruise participation as part of fieldbased training.

• Scientist at Sea (Eckerd College) provides undergraduate students with introductory, hands-on research experiences aboard active oceanographic cruises, with a focus on building technical skills and career exposure.

Additional opportunities may be listed on NSF-funded project websites, professional society job boards (such as AGU, GSA, or MTS), or distributed via listservs and social media platforms like Twitter/X and LinkedIn. Staying connected to these networks and letting faculty know of your interest can increase your chances of being invited to sea.

project management. These specialists manage science gear, troubleshoot technical issues, ensure data integrity, and work closely with scientists to execute successful research operations at sea.

Opportunities include: • UNOLS Tech Pool: A shared national pool of marine technicians supporting research across the UNOLS fleet. This system ensures vessels can access skilled personnel with the right technical background for each project. The Tech Pool is for those who already have experience going to sea on UNOLS vessels.

• Institutional Expertise: Certain institutions specialize in specific marine instrumentation.

For example: » Woods Hole Oceanographic Institution (WHOI) and Scripps Institution of Oceanography contribute to the Ocean Bottom

OUTCROP | January 2026

LEAD STORY NOAA’s Okeanos Explorer conducts ROV-based deep-sea exploration and streams live video and data in real time to shore-based scientists and the public. The Explorer-in-Training program provides undergraduate and graduate students with hands-on experience in ocean mapping and exploration technologies. Additionally, NOAA’s Teacher at Sea program allows K–12 educators to join research cruises aboard NOAA vessels, helping them translate ocean science into classroom learning.

USGS scientists sometimes join research cruises on UNOLS vessels, often as part of collaborative projects focused on seafloor habitats, methane seeps, sediment transport, and marine hazards. They also conduct independent marine fieldwork using NOAA vessels, chartered ships, or USGS-operated platforms.

While the agency does not run cruise-specific student programs, it offers hands-on research opportunities through internships and academic partnerships, especially in sedimentology, geophysics, and coastal ecology.

Seismograph Instrument Pool (OBSIP), with staff skilled in deploying OBS units, hydrophones, and seafloor sensors. » Oregon State University’s MARSSAM group leads many U.S. sediment coring & rock dredging operations, providing both equipment and specialized technical support.

• Shipboard Hiring: Operators such as Lamont-Doherty Earth Observatory (LDEO), WHOI, Scripps, Oregon State and many more institutions operating ships in the UNOLS fleet employ full-time technical staff to support various at-sea science operations where their contribution will involve deck work, navigation, seismic data acquisition, mechanical systems, and IT. • UNOLS MATE Internship Program: This long-running initiative places students and recent graduates aboard vessels to train in marine technology.

Interns gain hands-on experience with deployment systems, winch operations, sensor configuration, and deck safety.

• Industry Crossover: The R/V Marcus G. Langseth, originally built for oil and gas seismic exploration, frequently hires or contracts technicians with backgrounds in industry. Its complex equipment and operational demands are well suited to professionals with prior experience in offshore energy.

Outreach Specialists Many modern expeditions include dedicated roles for science communicators, educators, and artists-at-sea. These outreach specialists help bridge the gap between shipboard science and the public, using livestreams, classroom programs, blog posts, social media, and visual storytelling to share discoveries in real time. Candidates often have a STEM background paired with communication or education experience.

Federal Agencies: NOAA & USGS Opportunities Offshore research extends beyond the academic fleet. Agencies like NOAA and the U.S. Geological Survey (USGS) also operate missions where geologists, oceanographers, and educators can get involved. Their ships support a range of work, from deep-sea mapping to ecological surveys, and often welcome early-career participants alongside seasoned researchers.

OUTCROP | January 2026

Private and Nonprofit Opportunities Not all research cruises are part of the NSF-funded UNOLS fleet. Several high-profile research vessels operated by private foundations, nonprofits, or international organizations offer additional opportunities for scientists, students, and outreach professionals.

These vessels often focus on technology-driven exploration, public engagement, and open-access science.

• E/V Nautilus (operated by Ocean Exploration Trust) supports deep-sea exploration using remotely operated vehicles (ROVs), with an onboard team of scientists, engineers, and educators. The ship is known for its livestreamed missions, real-time science communication, and robust outreach programs.

• R/V Falkor (too) (operated by Schmidt Ocean Institute) focuses on cutting-edge oceanographic research and supports open sharing of data, imagery, and findings. Falkor routinely includes an artist-at-sea or outreach specialist as part of the science party.

• R/V Tara (run by Fondation Tara Océan) conducts global marine biology and climate missions, often with multidisciplinary teams that include scientists, educators, journalists, and documentarians.

LEAD STORY At this stage, estimating time for mobilization, equipment deployment, data collection, and transit is critical. Previous cruise reports and advice from vessel operators can help develop realistic schedules that align your science goals with operational limits.

• OceanXplorer (operated by OceanX) is one of the most advanced exploration vessels ever built, combining scientific research with high-end media production. OceanXplorer supports deep-sea exploration using submersibles, ROVs, and advanced imaging technologies. The ship’s missions often feature collaborations with scientists, educators, and filmmakers to expand ocean knowledge and inspire global audiences.

These ships often issue open calls for proposals or participation, and they tend to place a strong emphasis on interdisciplinary collaboration and broad public engagement.

One Year Before Sailing Once funding is secured, focus shifts to permits and logistics. Environmental permits, foreign clearances, and coordination with international partners should begin early, as they can take several months. A pre-cruise meeting, ideally 6 to 9 months before departure, should align science plans, workflows, deck layouts, and safety protocols. Researchers should also reserve specialized equipment during this window.

For more technical projects, this is the time to finalize equipment plans, system configurations, and integration of any personal instrumentation. Time estimates for mobilization, operations, and transits should be refined.

II. CRUISE PLANNING OVERVIEW

Planning a research cruise begins long before the ship leaves the dock. For National Science Foundation (NSF)-funded expeditions, this process often starts 18 to 24 months in advance, especially if you’re requesting a large vessel or specialized equipment. The timeline includes everything from submitting proposals and securing permits to assembling the right team and coordinating equipment needs.

Much of the best-practice guidance for cruise planning is provided by the University-National Oceanographic Laboratory System (UNOLS), a consortium of academic institutions and national labs that coordinate the U.S. Academic Research Fleet.

UNOLS supports efficient scheduling, technical readiness, and safe operations aboard federally funded vessels. Their website offers detailed resources on proposal forms, permitting timelines, equipment requests, and cruise planning.

If you’re preparing to sail with the U.S. Academic Research Fleet, early engagement with your vessel operator and close adherence to UNOLS guidance are essential. Cruise planning unfolds in several key phases to help ensure a smooth, efficient, and well-supported expedition.

One and Half to Two Years Before Sailing Planning begins with developing your NSF proposal and ship-time request. Early discussions with the vessel operator are important to confirm ship capabilities and equipment compatibility. Proposal budgets should include pre-cruise travel, technical services, shipping, and potential collaboration needs.

Vol. 75, No. 1 | www.rmag.org

Within 6 Months Before Sailing As the cruise approaches, technical planning ramps up. Complete the ship’s pre-cruise questionnaire, finalize lab and deck layouts, and confirm shipping and customs details. If bringing personal equipment, ensure it meets safety and technical standards.

By now, your data management plan should be in place, including arrangements to archive cruise data for future access.

This is also the time to start assembling your full team. Many cruises include graduate students, undergraduates, and early-career scientists who contribute to the project while gaining valuable field experience. If your cruise has open berths for students or outreach specialists, begin recruiting and confirming participants now. Connecting with your team early helps align expectations, assign responsibilities, and build familiarity before setting sail.

One Month Before Sailing In the final weeks, verify that all permits, shipping, and travel logistics are complete. Finalize medical clearances, safety training, and any special requirements for participants. If deploying ocean bottom seismometers or other long-term instruments, notify the vessel operator to coordinate logistics.

LEAD STORY medications, including extras.

• Keep medications in original containers in case customs requires verification.

• Carry any daily-use items like allergy meds, inhalers, or EpiPens.

Motion sickness is common, especially for firsttime sailors. Options like Dramamine or scopolamine patches can help, but they’re most effective when taken before symptoms appear, so consult your doctor in advance.

On many vessels, there is no doctor or nurse onboard. For example, the R/V Marcus G. Langseth relies on the Captain as the primary medical provider. The ship is equipped with a well-stocked ship hospital and has access to 24/7 telemedicine services, offering real-time consultation with physicians if needed.

If you have a pre-existing condition, share it with the operations coordinator or university staff ahead of time to assess risk and make sure proper arrangements are in place.

Don’t Let Paperwork Sink Your Cruise Missing deadlines or documents can jeopardize even a well-planned expedition. Fortunately, vessel operators and institutional support teams are available to help. Their expertise covers: • Technical specifications and system requirements • Letters of support for proposals • Logistics and equipment integration • Realistic schedules for operations and potential delays With early coordination and support from experienced teams, you can confidently plan a successful offshore research cruise.

III. CRUISE PARTICIPANT PREPARATION

Preparing to join a research cruise involves more than packing your sea bags. Each participant must complete a set of administrative, medical, and safety requirements to be cleared for embarkation. These steps help ensure the safety of the science party, crew, and vessel operations while also supporting coordination across institutions.

Delays or omissions in this process, especially for seismic or international cruises, can jeopardize participation. Permitting and clearance often require significant lead time, so it’s important to stay organized and communicate regularly with the vessel operator and university support staff.

Typical requirements include: • Passport or ID scans and visas, if entering foreign ports • Medical clearance, vaccinations, and emergency contact forms • Safety or civility-at-sea training (usually provided by the university) • Signed Statement of Responsibility outlining onboard conduct • Dietary restrictions or allergy declarations (to inform galley staff)

Health and Medical Preparation At sea, medical emergencies are more serious due to limited access to immediate care. Evacuation may take days. For that reason, plan ahead: • Schedule a routine medical and dental check-up before your cruise.

• Bring an ample supply of prescription OUTCROP | January 2026

Internet and Communication at Sea Internet access varies greatly across vessels.

Many now use Starlink or similar satellite systems, offering relatively stable access for messaging and basic browsing. However, dropouts are common and speeds vary with location, weather, and user traffic.

Before sailing: • Set recurring bills to autopay.

• Enable an automatic email reply.

• Download and test messaging apps like WhatsApp or Signal, which perform well with limited bandwidth.

Avoid planning for heavy data use like large file transfers or video conferencing unless specifically arranged. Assume communications will be basic, and plan accordingly.

Packing and Living Aboard Space is limited, so pack efficiently. Use soft-sided duffel bags or backpacks that fit into small cabin storage areas. Think utility and compactness: a mix between camping and lab life. Laundry facilities are PHOTO 13: MGL’s Bridge.

eye masks, and apps for white noise can help block out distractions.

Meals are served on a strict schedule three times a day, usually buffet-style, with hearty, calorie-dense options to fuel long work hours. Snacks, coffee, and drinks are available between meals. Galley space is shared, so clean up after yourself and respect meal times. Dietary restrictions must be communicated well before sailing; last-minute requests may not be accommodated due to remote operations.

Beyond work and meals, shipboard life offers limited but welcome downtime. Many vessels have a lounge with movies, a small gym, or a library. WiFi is normally available on most ships, often through satellite systems like Starlink, but bandwidth is limited. Email, messaging apps, and basic browsing are usually accessible, though speeds vary with location, weather, and user traffic. Streaming, video calls, or large downloads should be avoided unless specifically arranged with the vessel operator. Use the opportunity to unplug, read, or get to know your shipmates.

Newcomers will quickly notice that research vessels have their own language. A few quick translations: • Port = Left side of the ship facing forward • Starboard = Right side of the ship facing forward • Bow = Front of the ship • Stern = Back of the ship • Galley = Kitchen • Mess = Dining area • Head = Bathroom • Berth = Bed or sleeping area If a term or tool is unfamiliar, ask questions, curiosity is welcomed, and most crew or technicians are glad to explain. Every expedition is a learning experience, even for seasoned sailors.

Finally, respect is the foundation of life at sea.

Shared spaces require teamwork and patience. Keep your bunk tidy, respect quiet hours, be on time for meetings and drills, and always follow safety protocols. Only operate equipment you’ve been trained on.

A positive, flexible attitude goes a long way toward building camaraderie and ensuring your offshore experience is both productive and rewarding for everyone aboard.

community with its own routines, structure, and culture. Upon arrival, science personnel are typically greeted by crew members or marine technicians, shown to their cabins, and introduced to shared laboratory and living spaces. Accommodations are tight, and facilities vary by vessel, so arriving organized, adaptable, and with minimal luggage is key.

Depending on the ship, your cabin could range from a private room to shared quarters with up to eight bunks. Two-person cabins are fairly standard on most research vessels, but larger shared rooms are common, especially on older ships or those operating with big science teams. Space is limited, so soft-sided duffel bags and smart packing will make your life easier. Expect to share close quarters for several weeks, making personal organization and respect for others essential.

A mandatory safety orientation takes place shortly after boarding or before departure. This includes a walkthrough of critical areas, such as the bridge, galley, labs, and working decks, as well as instruction on muster stations, evacuation routes, and the use of life jackets and immersion suits. A full safety drill is conducted within 24 hours of sailing, often involving donning a survival suit and locating emergency gear.

Even experienced sailors should take these drills seriously; in a real emergency, clear knowledge of procedures can save lives.

Once underway, the ship operates around the clock. Research does not stop for sunsets, weather, or weekends. Most science teams work on fixed 12hour or 8-hour shifts, though some projects follow rotating 4-hour watches. You may be assigned to a day or night shift depending on project needs. Even if you’re not directly involved in running equipment, there is always work to do; prepping gear, assisting with deployments, logging metadata, monitoring instruments, or supporting recoveries. Every task matters, and shift handovers are critical to maintaining continuity. All work is logged in digital databases or physical notebooks, forming an essential record of the mission.

Prepare for your sleep schedule to shift dramatically. If assigned to nights, your body may need several days to adjust. It often feels like a bad case of jet lag, compounded by ship motion and noise.

When off shift, sleep whenever possible. Earplugs,

V. WORKING WITH MARINE TEAMS Research vessels operate under well-defined hierarchies to ensure safety, efficiency, and clear communication. The Captain has ultimate authority over all ship operations, while the Chief Scientist is responsible for delivering the cruise’s scientific objectives. Technical execution and coordination typically fall under a Lead Technician, who serves as a bridge between the science party, vessel crew, and shorebased support teams.

The Lead Technician oversees science operations, coordinates instrument deployment and recovery, manages acquisition systems, and ensures that both research goals and shipboard procedures remain aligned. On complex expeditions, technicians with specialized skills work alongside the science team to support every aspect of operations.

Technicians wear many hats, their roles vary by cruise type but often include: • Electronic & Communications Technicians: Maintain navigation computers, sonar systems, satellite communications, data networks, and shipboard IT infrastructure.

• Computer & Data Engineers: Oversee data acquisition, processing, storage, and real-time system monitoring to ensure data quality and integrity.

• Sonar & Survey Technicians: Deploy and operate multibeam echosounders, side-scan sonar, sub-bottom profilers, magnetometers, and other remote sensing tools.

• Winch & Deck Technicians: Manage corers, dredges, ocean-bottom seismometers, and streamers, ensuring safe and efficient overboard operations.

• Mechanical Technicians: Support deck systems, hydraulics, robotics, and deployed equipment essential to handling and positioning science gear.

• Surveyors & Geologists: Assist with seafloor mapping, instrument calibration, and preliminary interpretation of geophysical data.

VI. SCIENCE AT SEA

28

Offshore research builds on familiar geologic objectives such as mapping structure, interpreting stratigraphy, and investigating tectonic processes, but applies them in a remote, instrument-driven environment. Unlike onshore fieldwork, where geologists may often set their own pace, marine operations run on tightly structured shifts, coordinated teams, and synchronized systems. Understanding these workflows helps anticipate daily schedules, tool limitations, and operational constraints.

Marine geophysical cruises rely on continuous, large-scale data collection using a variety of tools: • Multibeam sonar provides high-resolution seafloor maps throughout the cruise.

• Sub-bottom profilers image shallow sediment structures below the seafloor.

• Seismic reflection surveys use long streamers and powerful sources to probe deep subsurface structure. These are among the most logistically intensive activities offshore. Deploying an 8–15 km streamer can take 12–24 hours; recoveries often exceed 12 hours. Source arrays take several hours to deploy and require servicing every 12 hours.

Long streamers reduce maneuverability and slow the vessel to 4.5–5 knots.

• Magnetometers and gravimeters passively log the Earth’s physical properties, with minimal intervention beyond initial setup.

• Sediment coring (gravity, piston, and multicore) recovers physical samples to support geophysical interpretations.

• Ocean Bottom Seismometers (OBS) record passive ground motion and are tracked acoustically for precise placement and later recovery.

flag gaps. Understanding the differences between raw, processed, and final data is key, along with knowing how files are organized and backed up.

Most systems use specialized software. Ask the lead technician early on about available tools and post-cruise needs. Vessels typically follow standard routines for backups, metadata, and file integrity.

Each cruise ends with a data package that may include: • Raw and processed data, Navigation and metadata logs, Survey summaries and cruise rep, Physical samples Confirm archiving requirements with the vessel operator or university before sailing. In the U.S., most data is archived through Rolling Deck to Repository (R2R), a national program that ensures long-term access and NSF compliance.

coordination, from permitting and protected species monitoring to international collaboration. These challenges provide a broader view of applied geoscience and expose participants to large-scale, interdisciplinary workflows that are rarely encountered in domestic land-based campaigns.

Offshore research isn’t just a change of scenery; it’s a chance to hoist anchor on a new chapter of your scientific journey. Whether you’re teaming up with marine crews or simply curious how those colorful seafloor maps come to life, life at sea expands more than just your geoscience toolkit. It shifts your perspective, deepens your skills, and gives you a frontrow seat to how Earth’s hidden stories are written beneath the waves. So, stow your gear, brace for adventure, and get ready to sail into science.

For those interested in a deeper dive, a follow-up article, Beneath the Waves: How Offshore Tools Reveal Earth’s Hidden Geology, takes a closer look at the technologies and techniques used aboard the R/V Marcus G. Langseth. It explores how seismic sources, streamers, multibeam sonar, coring tools, dredges, and ocean bottom sensors are deployed offshore to map the seafloor, image Earth’s crust, and recover physical samples. These tools not only reveal what lies beneath the ocean, but also help bridge offshore data with onshore geology.

VIII. A FEW KEY DIFFERENCES FROM ONSHORE FIELDWORK Working offshore shares many of the scientific goals familiar to field geologists, but the environment changes everything. Here are a few of the most notable differences: • Time and Schedule: You don’t control the clock.

Shipboard schedules are dictated by operations, weather, and daylight (if applicable). Patience and flexibility are crucial.

• Instrument-Based Workflows: Instead of rock hammers and field notes, you’ll rely on complex instrumentation, streamers, sonars, corers, and navigation systems, to gather indirect data from beneath the seafloor.

• Chain of Command: Communications and decisions follow a strict structure, from the Captain to the Chief Scientist and technical leads. Respecting this hierarchy keeps operations safe and efficient.

• Limited Personal Freedom: A research vessel is a closed environment. There’s no stepping away for a break or driving to the next site. Collaboration and adaptability become essential life skills.

• Emergency Protocols: From equipment failures to medical incidents, all responses follow predefined procedures. Know your role and muster station before you sail.

• Multidisciplinary Teams: You’ll work alongside oceanographers, engineers, technicians, and students. Embracing different perspectives strengthens both the science and the shipboard experience.

• Pack what you’ll need: There’s no Home Depot or CVS around the corner. Careful planning, backup supplies, and a few well-chosen redundancies can make all the difference once you’re offshore.

IX. BRIDGING THE GAP

For field geologists, offshore research may feel unfamiliar at first. You trade outcrops for instruments, but the goals remain the same. Marine geophysical cruises expand your skillset with tools like subsurface imaging, geospatial analysis, and systems integration, skills that complement and enhance traditional fieldwork.

Cruises also offer experience in complex OUTCROP | January 2026

The Ongoing Development of the Upper Cube Adding Sticks Across the Uinta Basin

By Riley Brinkerhoff, HIVE Partners As such, Upper Cube stratigraphy is distinguished by argillaceous mudstones, lack of molluscan fauna and interspersed, rather isolated, fluvial-dominated deltaic sets. In the deep Uinta Basin where it has proven oil production, it ranges from 800’ to 1700’ thick. Hydrocarbon productivity in this member is strongly influenced by its depositional and burial history, which controls organic richness, thermal maturity, and reservoir quality. Unlike the more prolific Uteland Butte, the Upper Cube’s hydrocarbon potential is largely limited to portions of the Uinta Basin where it has achieved a thermal maturation of at least 1.0 VRo. Otherwise, connate waters from poorly to completely uncharged dolostones and sandstones tend to overwhelm potential oil production.

The presentation will close with some predictions for the Uinta Basin Upper Cube, both on where nearterm development will occur, plus what drivers and risks operators are considering.

After large deals in 2024 and increased rig-counts in 2025, Uinta operators are searching for new reserves in 2026. Low oil prices and a need to find value in existing acreage means that everyone has to make bigger wells with less. Enter the Uinta Upper Cube.

This presentation will briefly review the status of the Uinta horizontal oil play, what zones are being targeted and where, and the results that different operators are seeing. Providing a definition of the upper cube, why it is developed separately from the lower cube, and what drillable zones exist within it. Following with an examination of the technical limits for the play, and what may be done to expand it, including the wells that have tested it so far.

Upper Cube rocks of the Green River Formation in the Uinta Basin of NE Utah represents lacustrine sediments from fluvial-deltaic sediments of the Douglas Creek Member to the rich oil shales and argillaceous dolostones of the overlying Parachute Creek Member.

RILEY BRINKERHOFF is a petroleum geologist and most recently helped found HIVE Partners, which is focused on Uinta horizontal developments. In 2024, he raised $30 MM and spearheaded the successful Upper Cube NE extension. In 2025, HIVE raised another $120 MM and is pushing new Upper Cube wells across the Uinta Basin. Prior to HIVE, Riley served as exploration manager for WEM beginning in 2019, raising $550 MM for various Uinta Basin developments, most particularly as the exploration geologist in 130 playexpanding wells in five distinct target horizons. Before WEM, he worked as an asset and BD geologist at Newfield, SM Energy and QEP. He started his career at BP America.

RMAG ON THE ROCKS

THE ACTIVE VOLCANO IN RMAG’S BACKYARD DOTSERO VOLCANIC CRATER SEPTEMBER 14, 2025

By Shannon Rentz & David Schoderbek visible in narrow canyons between the highway and the crater. Figure 2 shows the view from the near the vent on the north side of the crater, looking south across the Eagle River valley.

INTRODUCTION On a perfect Colorado late summer Sunday, Dr. Wendy Bohrson and PhD Candidate Valerie Strasser led the On The Rocks group into the belly of the (extinct) beast. In the categorization of volcanologists, the Dotsero volcanic crater is technically still active. The most recent group of eruptive events took place approx. 4,150 years ago (Sweeny et al., 2018). According to the USGS, an “active” volcano has erupted within the last 10,000 years.

The Dotsero site is an excellent combination of accessibility, exposure, and interesting maar-type structural elements preserved from the threephase eruption activity.

GEOLOGIC SETTING AND PREVIOUS WORK

LOCATION

The eruption crater is barely visible looking north from I-70 at Exit 133. The most distal outflows from the first eruptive pulse of the Dotsero Volcano traveled all the way south across the Eagle River Valley and likely dammed the river temporarily. Trachybasalt lavas are also present beneath Interstate 70 (See Figure 10) and are

The crater location is within the northern extent of the Rio Grande Rift (Figure 3), between the Gore Range to the north, and the Sawatch Range to the south. The hotly debated origins of the rifting aside, the Dotsero volcano erupted trachybasalts in a multi-pulse, relatively short-lived eruption (Sweeny et al., 2018). Eruptive products included both magmatic and phreatomagmatic deposits that occurred in three phases with deposition likely controlled by paleotopography.

The extensional tectonic regime that produced the rift likely began ~38-35 Ma in the southern extent, with the major rift opening into the modern configuration ~ 21 Ma (Van Wijk et al., 2018).

The crater and accompanying pyroclastic and

Note the travel distance of the trachybasalt flow (unit Qtb), which crossed the valley to the south of the crater, and the aerial extent of the unconsolidated lapilli tuff falls surrounding the crater and to the northeast.

FIELD OBSERVATIONS

Previous work in the field (Sweeny et al., 2018) identified three magmatic pulses of activity and described it thusly: Dotsero eruptive products “...record evidence of a progression from effusive magmatic activity through explosive phreatomagmatic maar-forming activity to a final explosive magmatic phase.” The field trip group observed the evidence described by the authors in person.

Land Management is the administrator of this location, and information may be found at https://www. blm.gov/visit/dotsero-crater-rec-site. The ease of access to the location combined with the variety of volcanics available to explore, should entice any volcano aficionado to make the stop in Colorado and visit the crater in their backyard.

• Celadonite Alteration: Likely green celadonite vug and fracture linings were noted at Dotsero by Ron Parker. Ron reported on this mineral and its presence in the San Juan volcanic rocks near Pagosa Springs (https://issuu.com/rmagdenver/docs/ oc_2024-06_june_v02/52). At Dotsero (Figure 11), the green phase appears to also be present as a pervasive alteration product. The green vug and fracture coatings and alteration are hard (>5), i.e., harder than one would expect for celadonite (~ 2); but this might be due to some retained hardness associated with the host basalt.

CONCLUSIONS

The Dotsero eruption left behind interesting evidence of various intra-plate volcanic processes. Excellent work has previously been done in the area, and there are opportunities to build upon that and learn more about the tectonic and eruptive factors that influenced magmatism in the area. Site access does require a 4-wheel drive vehicle with high clearance, but is quite close to the road. The U.S. Bureau of OUTCROP | January 2026
