Description The British Antarctic Survey (BAS) are seeking to employ a dynamic Sea-Ice Physicist to work on a NERC funded project entitled Eco-Light. This project aims to better understand how the changes in the light climate, which is driven by changes in the snow and sea-ice regimes, influence the timing and duration of primary production events, as well as changes in the grazing habits of zooplankton. The project involves both observations and numerical modelling. The successful candidate will to be needed to upscale the light regimes in snow and sea ice to the pan-Arctic scale in order to improve simulation and prediction of the Arctic sympagic ecosystem. They will blend pan-Arctic snow and sea ice thickness products with accurate light extension coefficients for snow and ice. This
