To estimate carbon and nitrogen uptake of phytoplankton at different locations, productivity experiments were conducted by incubating phytoplankton in the incubators on the deck for 3-4 hours after adding stable isotopes (13C, 15NO3, and 15NH4) as tracers into each bottle. Productivity experiments were completed during three cruises. The samples for productivity were collected by CTD rosette water samplers at 6 different light depths (100, 50, 30, 12, 5 and 1%). To understand the spatial distribution of phytoplankton productivity and to assess effect of climate change on ocean ecosystem, productivity experiments were executed in the Amundsen Sea, Antarctica.
Year-round records of temperature, humidity, pressure at the GPS stations around the Jang Bogo Station
Meteorological observation was carried out at the King Sejong Station in 2018. Observational elements are composed of wind, air temperature, relative humidity, station level atmospheric pressure, solar radiation, longwave radiation, UV radiation, and precipitation. Goals of this observation are 1) to understand meteorological phenomena and 2) to monitor climate change at Antarctic Peninsula. These data are recorded automatically then examined by meteorological expert at the station to be produced as a daily, monthly, and annual report. To understand weather phenomena and to monitor climate variability at Antarctic Peninsula
In order to model the distribution and physiological response of Antarctic pearlwort, we obtained 1,150 data points (Po, average 96.7) of distributions and physiological response observations in the vicinity of Sejong Station, King George Island, Antarctica in 2016. In addition, we obtained 1,150 data points (Pe, average 133.1) of expected values made from modeling equation for this species. With these data, the prediction accuracy of the model acquired in 2017 was 72.6%. 남극개미자리의 분포와 생리반응 모델링을 위해 2016년 남극 킹조지섬 세종기지 부근에 분포하는 남극개미자리 분포와 생리반응 관측치 1150건 확보(Po, 평균값 96.7), 이들의 시뮬레이션을 통한 예측치 1150건 확보(Pe, 평균값 133.1). 이들 데이터를 활용하여 2017년 확보한 모델의 예측 정확도는 72.6%.
