TheearlieststudiesoftheoceansdatebacktoAristotle(384BC 322 BC),butatruemethodologicalapproachonlybeganabouttwomillennia afterhisdeath.Initially,oceansciencederivedfromthepracticalartsof navigationandcartography( Henry,2008).Duringthe15thcentury, logbooksandannotatednavigationmapsbegantobecollectedsystematically.Unfortunately,fewearlytravelrecordshavesurvivedduetophysical deterioration,lossoflogbooksorprivacypolicies(Petersonetal.,1996 ). WiththePortugueseexplorationofnewlandsandseas,important advancesweremadeinonebranchofscienceinparticular:thegeography ofthesea.

The firstmethodologicalandtechnologicalapproachtoobservingthe seawasestablishedatthemeetingoftheRoyalSocietyofLondonon June14,1661.Thedocument PropositionsofSomeExperimentstoBeMade bytheEarlofSandwichinHisPresentVoyage (Birch,1760)definedtheguidelinesfordatacollection.

“Diligentobservations” wererequiredbyGalilei(1564 1642)andwere thebasisofhisexperimentalmethod.Theconceptwasunderlined,interalia, inthe “ForthDay” chapter,discussingthecausesofthetides,inthefamous book DialogueontheTwoChiefWorldSystems (Galilei,1632).The “Propositions” wereaskingfor “diligentobservations” andtheirrecommendations weresubsequentlyincludedinthe DirectionsfortheObservationsandExperimentstoBeMadebyMastersofShips, Pilots, andOtherFitPersonsonTheir Sea-Voyages by MurrayandHooke(1667) onbehalfoftheRoyalSociety. Seafarerswereaskedto -Observethedeclinationandvariationsofthecompassorneedlefromthe meridianexactly,inasmanyplacesastheycan,andinthesameplace, everyseveralvoyage, -Carrydipping-needleswiththem, -Markcarefullythe flowingsandebbingsofthesea,inasmanyplacesas maybe,

The “Directions” wereaccompaniedbyinstructionsontheuseof methodsandinstruments.Theoretically,theyconstitutedasystematization ofageneralrequestbyseveralEuropeanscientistsmadeexplicitbyVincenzo Viviani(apupilofGalileoGalilei),onbehalfoftheAccademiadelCimento togatherknowledgeofthevariabilityofoceancirculationbymeansof “diligent” observationsofthesea(see Pinardietal.,2018).Itisworthwhileto mentionthattheAccademiadelCimentomottowas “bytryingandtrying again” (e.g., Magalotti,1667).

Afurthersteptowardamore “diligent” observationalmethodologywas madebyFerdinandoMarsili(1658 1730)withhisfamoustreatise “OsservazioniintornoalBosforoTracio” (Marsili,1681).Forthe firsttime,an appropriateobservationstrategywasdefinedinordertounderstandtheeffectsofdensitydifferencesonthecirculationofwatermasses(Pinardietal., 2018; Petersonetal.,1996; Deacon,1971).

TheeffortsoftheRoyalSocietytogaingreaterknowledgeofthephysicalcharacteristicsoftheseametwithlittlesuccess.However,animportant contributioncamefromWilliamDampier(1651 1715),whowasthe first persontocircumnavigatetheglobethreetimes(Dampier,2012).InDampier’srecords,datawerenotreportedasrequestedinthe “Directions,” but containedsubstantialinformationonwindsandcurrents.Theessay “A NewVoyageRoundtheWorld” (Dampier,1703)wassenttotheRoyal Societywiththeaimtopromote “usefulknowledge,andofanythingthat mayneversoremotelytendtomyCountriesadvantage.” Duringhisvoyages,Dampierfoundthatcurrentsintheequatorialregionweredrivenby thetradewinds(Deacon,1971).

Thewestwardcurrentsinthenorthequatorialregionwereusedduring thediscoveryofAmericaandwereassociatedwiththeAristotelianconceptionofseamotion.Inactualfact,Aristotleneverspokeofawestwardsea flow,butthiswasthescholarlyinterpretationofapassageinthesecond bookof Meteorologica (e.g., Aristotle,1952):

ThewholeMediterranean flowsaccordingtothedepthofthesea-bedandthe volumeoftherivers.ForLakeMaeotis (AzovSea) flowsintothePontusand thusintotheAegean Intheseasmentionedit (the flow) takesplacebecause oftherivers formorerivers flowintotheEuxineandLakeMaeotisthaninto otherareasmanytimestheirsize andbecauseoftheirshallowness.Forthe seaseemtogetdeeperanddeeperthanLakeMaeotis,theAegeandeeperthan thePontusandtheSicilianSeadeeperthantheAegean,whiletheSardinian andTyrrhenianarethedeepestofall.ThewateroutsidethepillarsofHeracles isshallowbecauseofthemudbutcalmbecausethesealiesinahollow.

Thewestward flowofthesurfacecurrentsinthenorthequatorial regionwasnotedbyPietroMartired’Angera(1457 1526)inDeOrbe Novo,3rd “Decade,” Book4oftheEnglishtranslationbyMacNutt(Martyr d’Anghiera,1912):

Speculationonthepropertiesoftheoceansduringthe17thcenturywas providedbymanyskilledpeople(“virtuosi”). Galileo’sstudies(1638) on fallingbodieswerethebasisofmany “inquiries” relatingtosurveysofthe sea.Boyle(1627 1691)andHooke(1635 1703)spentconsiderabletime testingandapplyingtheconceptof “gravitation” tooceanstudies.

Boyleaskednavigatorstoexplorethedifferentaspectsoftheoceans: withregardtothewateraretobeconsideredthesea,itsdepth,specificgravity,differenceofsaltnessindifferentplaces,theplants,insects,and fishesto befoundinit,tides,withrespecttotheadjacentlands,currents,whirlpools, &c(Shaw,1738).Therequirementsfortheseobservationswereexplainedin detailinthe “Directionsfortheobservationsandexperimentstobemadeby mastersofships,pilots,andother fitpersonsintheirsea-voyages” thatalso containedinformationontheinstrumentsthatshouldbeusedroutinely forthecollectionofgeographical,atmospheric,oceanographic,andbiologicaldata.

The “Directions” werethe firststepinthecreationofadataqualitymanagementsystem:

• essentialinformationdescribingthesensorsandplatforms,

• measurementposition,

• measurementunits,

• processing,dateandtimeinformation.

Duringthe17thcentury,scientistsbegantodefinesomespecific inquiriesonnaturalphenomena(e.g.,tides,currents,winds).Thediverse

interpretationsofobservationsorresultsof “experiments” madeitnecessary toadoptpreciseexperimentalmethodologies.Theconceptofstandards agreeduponbythescientificcommunityandnowadoptedineveryday practicedidnotexistthen.The “bestpractices” weredefinedbyoneor morehighlyreputablepeople(personsofgreatrepute),oneofwhomwas RobertHooke,whopresentedthe “MethodofMakingExperiments” to theRoyalSociety(Derham,1726).Hooke’sexperimentalmethodincluded somespecificrecommendations:

Sounding: NuntiusInanimatus, EsploratorDistantiae

Oneofthemajorproblemsofthe17thcenturywasthelackofgoodmaps withmarinetopographyforuseinthe ArtofNavigation, oneofthemostuseful intheWorld (Derham,1726).

Thesoundinginstrumentillustratedinthe “Directions” wasaballmade ofwaterproofedlightwood(e.g.,maple),towhichanironorstoneweight wastied.Whenittouchedtheseabed,thewoodenballcameoffandroseto thesurface(Fig.1.2).Thedepthwascalculatedwithtablesonthebasisofthe timetakenbytheballtodescendandascend.The “Directions” provided warningsontheweightsanddimensionsofthedifferentpartsofthe apparatus.

Hookegavepreciseindicationsonthedifferentcomponentsof “instrumentsforsoundingthegreatdepthofthesea”,andhighlightedtwopossible technologicalsourcesoferrors:The firstwas,that “itwasnecessarytomake

WhileHookeacknowledgedtheerrorintroducediftheballwas notdetectedimmediatelyuponreachingthesurface,hedidnotrealizethe difficultyofdoingsoinanythingbutatotallycalmsea.Manywere thecomplaintsastothedifficultiesinlocatingtheballuponitsreturnto thesurface.

Hookewasawareoftheerrorsassociatedwithcalculationsofdescent andascentspeedsandoftheneedtoconsiderthebuoyancyofthematerials usedforthevariouscomponentsofthesoundingapparatus.Onthecontrary,hewasconfidentoftheuseofthe “pendulumclock” describedin “PhilosophicalExperiments” (Derham,1726).Toavoidproblems,he proposedacone-shapedsoundingmachine(Fig.1.3)withasmallholeto receivewaterbasedonexternalpressure(NuntiusInanimatus or Explorator Distantiae).InHooke’sidea,theincreasingpressureofseawateratdepth would fillthesoundingmachineinproportiontotheactualdepth.Therefore,byweighingthecontentofthewaterinitafteritreturnedtothe surface,itwouldbepossibletohaveameasurementofthedepthof thewater.

Whatevertheoperationofthis Nuntius,Hookewassurethatthesea temperaturewouldinfluencetheresults,astheheatorthecoldcaused theaircontainedinthemachinetoexpandorcontract.Forthisreason, hethoughtofaddingatemperaturesensitiveapparatus.However,there wasanotherimportantquestiontoanswerbeforeevaluatingtheresultsof asoundingapparatus, thatis, “WhethertheGravitation,towardstheCenter oftheEarth,docontinuethesame,atanyDepth;orwhetheritdoincrease
