An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.
During six days of observations, the team was able to retrieve temperature and other data at 67 sites covering the entire continental shelf region off the Totten Ice Shelf, the floating portion of the Totten Glacier. The study enabled the team to obtain an overall picture of warm ocean water flowing into the ice shelf cavity.
The team, including Assistant Professor Yoshihiro Nakayama and Associate Professor Shigeru Aoki of Hokkaido University's Institute of Low Temperature Science, conducted helicopter-based observations with cooperation by Japan's Maritime Self-Defense Force as part of the 61st Japanese Antarctic Research Expedition .
The team found that broad ocean heat -- stretching across the 150-kilometer range between the longitudes of 116.5° east and 120.5° east -- was intruding toward the shelf. Seawater with a temperature of about 1 degree Celsius higher than the freezing temperature was observed between 50 and 100 meters above the seabed. This showed, for the first time, the overall picture of warm water mass flowing toward the Totten Ice Shelf.
