内容記述 | Global climate closely links with the Arctic Ocean ecosystem especially in the Barents Sea. The distributions and correlations among chlorophyll-a (CHL), sea ice concentration (ICE), wind speed (WIND), sea surface temperature (SST) and mixed layer depth (MLD) are studied within the region of Barents Sea (70°N-80°N, 30°E−40°E) over the period 2003–2013. CHL increased from north to south in general. Ice melted rapidly in the southern region (70°N-75°N) and had less impact than SST on phytoplankton blooming. Melting ice in northern region (75°N-80°N) contributed significant source on phytoplankton development. WIND had negative correlations with CHL in spring blooming season and had positive correlations during autumn. Dimethylsulfide (DMS) concentration and sea-to-air DMS flux are simulated using a comprehensive biogeochemical model. The key model parameters are calibrated using a genetic algorithm under contemporary climate conditions. Environmental factors and DMS sea-air flux are compared for 1CO2 and 4CO2 climate conditions. By 4CO2, SST increases more than doubles, DMS increases 27.5%. Mean annual DMS sea-to-air flux increases 323%. The increase of DMS flux under 4CO2 conditions indicates that Arctic climate may be counteracting with the warming by 4CO2. |
