Snow Core Accumulation from Delta-15N Isotopes

Project description

Investigating snow cover variations in Antarctic sea ice using nitrogen isotopes

Understanding the real threat posed by a future sea level rise requires a better understanding of how the mass balance of the East Antarctic Ice Sheet responds to climate change: increased ice losses may be partly offset if warming also causes increased snow accumulation in this large ice sheet in Antarctica. Current understanding of how snow accumulation rates change in response to climate change is limited as modern records are sparse and the deuterium ratios used as a proxy for ice accumulation are affected by several other climate variables. The EU-funded SCADI project aims to develop an independent methodology to infer past snow accumulation rates using the fractionation of nitrogen isotopes in nitrate.
