High Resolution Ocean Color products estimation in fjord of Svalbard, Arctic Sea.

Ocean Color data are used to understand marine ecosystem. In high latitude region, ice melting optically influences the ocean color product. In this study, we assessed an optical property in fjord around Svalbard, and estimated distribution of chlorophyll-a and suspended sediment by using high resolution satellite data, Landsat-8 OLI. To estimate chlorophyll-a and suspended sediment concentrations, various regression models were tested with different band ratio. Regression models were not shown high correlation because of the temporal difference between satellite data and in-situ data. However, model-derived distribution of ocean color product by OLI showed possibility that a fjord and a coastal area around Arctic Sea can be monitored with high resolution satellite data. To understand climate change pattern around Arctic Sea, we need to understand what ice meting influences on marine ecosystem change. Result of this study will be used to high resolution monitoring on ice melting and its influences on the marine ecosystem change at high latitude. KOPRI (Korea Polar Research Institute) has been operated the Dasan station on Svalbard since 2002. This study has been doing based on this Korea Arctic station.
