David Nielsen

 

I am a Postdoc in the Ocean Biogeochemistry group, currently working in topics related to the Arctic carbon cycle, using global ocean and Earth system models of various resolutions (km-scale) as tools.

I have a background in Environmental (BSc) and Biosystems Engineering with a focus on Meteorology (MSc), and Earth System Science (PhD). Thesis: "An Earth system modelling perspective on Arctic coastal erosion under climate change" [Thesis PDF]

Projects I am/was involved in:

• CLICCS A5: The Land-Ocean Transition Zone
• CLICCS A1: Carbon Dynamics in the Arctic
• CLICCS A6: Earth System Variability and Predictability
• EU Horizon 2020 Nunataryuk: Coastal permafrost research, combining modelling and socio-economic analysis, from local communities to the pan-Arctic scale.
