Summary
The Amundsen Sea is at the center of the world's most rapidly warming area, where many believe the collapse of ice shelves and glacier is just a matter of time. Upwelling of deep warm water into the continental shelf plays a significant role in this regard by melting the base of the floating ice shelves, but the overall loss is a combined result of ocean-ice-atmosphere interaction. The objectives of the KOPRI Amundsen project are to assess the changes of the ocean processes due to the Western Antarctic warming and glacial melt-water dispersion via multi-national operation of the Earth observing network. During phase one(2010-2016), this project investigated ocean circulation patterns and heat flux to the Antarctic coast, ecosystem structures and diversities, and biogeochemical cycles in the study area. In the phase two(2017-2019), the project is focused on the ice shelf melting and retreat, the effect of meltwater discharge to the oceanic physical and chemical processes, and the subsequent changes in the biogeochemical processes and food web structure. The project produced high-impact scientific findings from the major areas of the research(illustrated in the figures) in 2017, and carries out its 5th field expedition to the study area from 2017 December to 2018 February.
