Mr James Crosby


My PhD research looks at the biogeochemical impact of exported nutrients from the Greenland Ice Sheet on coastal environments and ecosystems. Ice sheets have recently been identified as important sources of bioavailable nutrients to the world's oceans, with potentially significant implications for global biogeochemical cycles, and at a more local scale the vast fisheries of the North Atlantic that hold key socio-economic value. Little is known about the potential impact of these exported nutrients, and is an area of particular concern given global warming and its implications for the Greenland Ice Sheet. As such, a combined field/numerical modelling investigation will explore fjord biogeochemical dynamics to identify nutrient processing in these dynamic environments and identify likely future variations in the supply of nutrients to Greenland's coastal oceans and its associated fisheries.
