• To assess the rapid warming of the Amundsen, and related physical, chemical, and biological processes
• To assess the impacts of the warming on the biology and biogeochemistry in the region
• To understand the temporal and spatial distributions of the climate gases
• To document changes in hydrography and biogeochemical cycles associated with ocean currents and sea ice variabilities
• To examine the links between biogeochemical processes and food web structure
• To study and predict the impacts of the combined changes in ocean physics, biogeochemical capacities, and marine ecosystems in polar waters
• Flow patterns of the Amundsen coastal currents over the continental shelf and in the trough channel (JPO 2014).
• Net Community Production from the Amundsen Sea measured by the del O2/Ar method (JGR Oceans 2014).
• Recent trends of the Amundsen local climate change, and its linkage to the global ocean temperature variation (Science 2014)
• To strengthen the scientific basis that help understand the issues of environmental changes in global perspective
• To upgrade the Korea's standing to a major scientific contributor by conducting internationally networked research in poorly explored polar regions.
• To establish long-term data base and specimen archives on the physical changes and biodiversity and ecosystem functioning in the study area.

• 1. Satellite image of the Amundsen Sea study area taken during 2012 expedition. Ship track in red, frozen sea shown as white. Antarctic continental glacier are the white along the coast at the bottom of the picture. Black is the polynya, a huge melt pond amongst frozen sea, due to the intrusion of relatively warm deep water from ocean.
• 2 Araon reached the deep down South, facing the white cliff of the ice shelf, which is a hang-over of the Antarctic continental glacier on the sea water.
• 3. In the midst of sea ice, Araon crew aboard a Zodiac boat is retrieving the surfaced mooring device that was deployed a year ago and now loaded with priceless scientific data.
