WP3: Oil Spill Remote Sensing
Satellite remote sensing is an ideal tool for detecting and characterizing marine surface slicks. In the Arctic environment can such slicks be made up of, e.g., mineral oil, algae blooms, and newly formed sea ice.
Improved knowledge about the behavior and fate of mineral oil in icy waters aids protecting precious marine and coastal environments in the case of pollution. In addition, global warming makes phytoplankton blooms become more common. Hence, a natural extension of our research is to include studies of marine primary production and water quality.
We develop remote sensing technologies for marine surface oil detection and characterization, and to improve modeling of oil behavior and fate in icy waters, both those of anthropogenic and natural origin. During oil spill clean-up operations, authorities need to know where thicker mineral oil is located, and where it may be moving due to wind and ocean currents. By combining synthetic aperture radar satellite images and numerical modelling, we can identify an oil slick and predict where it is heading.
The Norwegian coastline is dominated by long and narrow fjords, and the water there is a mix of saline seawater and freshwater from land. In fjord sea ice with mixed salinities, oil behaves differently as in the open sea ice. This may have an impact in case of a near-costal oil pollution incident and hence forms another research direction.
