In situ Calibration/Validation Measurements of  Remote Sensing Reflectance for the Arctic — PI: Dr. Anders  Jensen Knudby. Ocean-colour remote sensing is used to  monitor a multitude of physical and biological characteristics and changes in  our oceans, and to produce bathymetric maps (maps of seafloor habitats). This  technology relies on atmospheric radiative transfer models calibrated with data  from low-mid latitudes, and frequently fails in the Arctic, where the humidity  and composition of the atmosphere is different. Since global environmental  change is most rapid in the Arctic, there is a need to address this situation. This project aims to improve atmospheric  correction for the Arctic, for current and future ocean-colour sensors. The  team will produce a large dataset containing field observations of the  water-leaving light field, as well as ancillary information on water depth,  benthic habitat and water quality. This will allow researchers to test and  improve their calibration/correction approaches.
