Dr. Kenji Yoshikawa, a research professor, works at the Water and Environmental Research Center, University of Alaska Fairbanks, USA. His areas of research are permafrost geomorphology, permafrost hydrology, and extraterrestrial (Martian) permafrost, but pingos and icings are his primary interest, searching for them and drilling them to learn more including two difficult quests by Yoshikawa—one into interior Antarctica and the other across the Sahara for ancient pingo scar—are described his biography by Ned Rozell in the book Finding Mars. Yoshikawa’s research locations have included Svalbard, Greenland, Alaska, Siberia, Tibet, Canadian Arctic, and Mongolia, where he has located many pingos and examined their internal structures and hydrology. He organized and took part in many field investigations, including searching the permafrost at Mount Kilimanjaro, Mexico, Hawaii or Peruvian Andes. He has published more than 50 peerreviewed papers as the first author or coauthor during the recent years. He also has made contributions to books and academic conferences, and is invited to give keynote lectures at several universities and institutes.
Future data will be updated by monthly. Many sites have available data, but time constraints did not allow for calculation of the mean annual temperature and freezing/thawing degree days by the time of this publication.
