The Japanese observation ship Shirase has commenced intensive scientific observations near the Totten Glacier in East Antarctica, focusing on the glacier’s melting mechanisms.
The Japanese Antarctic observation ship Shirase, carrying the 67th Antarctic research team led by Captain Shigeo Aoki, has begun intensive observations off the Totten Glacier, one of the largest glaciers in East Antarctica, as of June 6. The Totten Glacier is known for its accelerated melting, and the research team aims to investigate approximately 30 locations around the glacier to understand the mechanisms of melting and potential impacts on marine life until June 26.
This year's mission operates under a 'two-leg system' where the team will make two round trips between Australia and Antarctica, with the observations at Totten Glacier being a crucial part of their agenda, involving a large number of researchers. The team has already started deploying sensors to measure seawater temperature, salinity, and has begun plankton collection, setting a positive tone for the mission, according to Daisuke Hirano from the National Institute of Polar Research.
Hirano expressed confidence in the observations stating that this is the first time such extensive studies of the Totten Glacier region are being carried out in a single voyage, highlighting the advantageous conditions this year with reduced sea ice. Captain Aoki also shares optimism regarding the potential discoveries in their research endeavors, noting that unprecedented observations seem likely this season, emphasizing the mission's significance amid the ongoing climate changes affecting the Antarctic region.
