The 7th SOOS Scientific Steering Committee Meeting Held in Hangzhou


On May 9th, 2018, experts specialized in international Antarctic and Southern Ocean from Australia, the United States, Germany, the United Kingdom, Italy, Norway, Sweden, New Zealand, South Korea, Turkey, and the Netherlands, and Chinese experts specialized in polar science and marine science participated in the Scientific Steering Committee of the Southern Ocean Observing System (SOOS) in Hangzhou.

    In 2000, the International Hydrographic and Geographical Association defined the entire ocean south of 60 degrees latitude as the Southern Ocean. Scientific Committee on Antarctic Research (SCAR) and Scientific Committee on Oceanic Research (SCOR) initiated The Southern Ocean Observing System (SOOS) on Autumn, 2010. Academician CHEN Dake from State Key Laboratory of Satellite Ocean Environment Dynamics, SIO, SOA was selected as the member of the Scientific Steering Committee of SOOS, as well as the representative of SOOS in China.

    The goal of the Southern Ocean Observing System (SOOS) is to address the six major challenges of the Southern Ocean Science: (1) the role of the Southern Ocean in global thermal balance and freshwater balance; (2) the balance of the overturned circulation in the Southern Ocean; (3) the role of the ocean in the stability of the Antarctic ice sheet and its contribution to sea level rise; (4) trends and consequences of carbon absorption in the Southern Ocean; (5) future changes in Antarctic sea ice; (6) the impact of global changes on the Southern Ocean ecosystem.  SOOS has currently got the international support from The Scientific Committee on Antarctic Research (SCAR), Scientific Committee on Oceanic Research (SCOR), Census of Antarctic Marine Life (CAML), Global Ocean Observing System (GOOS), Partnership for Observation of the Global Oceans (POGO), World Climate Research Programme (WCRP), etc.

    During December 6th, 2009 to February 20th, 2010, China's 26th Antarctic expedition team successfully conducted submarine observations for the first time in the Southern Ocean. The submersible system was launched in the Gulf of Prydz Bay, about 60 nautical miles from the Chinese Antarctic Zhongshan Station, and obtained time-series observation data for more than two months. The submersible system is mainly composed of a temperature salinity collector, a sediment trap, an acoustic subliminal Doppler current profiler, and a float ball assembly. It mainly performs long-term observations on the temperature, salinity, and velocity of the Southern Ocean. The process of the formation and maintenance of the interglacial lake in Prydz Bay was analyzed to provide support for the study of the interaction between ocean, sea ice, and atmosphere in the seas surrounding the Antarctic continent. Later, under the guidance of the goal of“Human Peaceful Utilization of the South Pole”, Chinese scientists continued to contribute to the observations of the Southern Ocean.     The convening of the SOOS Annual Conference in China provided Chinese scientists with an opportunity to fully demonstrate Antarctic research on the international stage. The views and efforts of Chinese scientists have been universally recognized by the international polar research community. Director QIN Weijia of the Polar Research Institute of China, Deputy Director XU Ren ofthe Polar Research Institute of China, and Deputy Director General HUANG Daji of the Second Institute of Oceanography, the State Oceanic Administration, attended the conference to congratulate and introduce the scientific research and scientific plans of the Chinese Antarctic scientific expedition and Chinese polar studies. .

The SOOS Executive Committee Meeting, the SOOS Scientific Steering Committee Meeting, the SOOS Data Management Subcommittee Meeting, and the Southern Ocean Numerical Simulation Symposium were held during May 6-11 at SIO and Hangzhou Jinxi Hotel separately. Chinese and foreign scientists had in-depth discussions on physical oceanography, marine chemistry, marine geology, the collection, sharing, and numerical modeling of basic observation data of marine ecology in the Antarctic and Southern Oceans.
