RU2: Methane, nutrients and carbon
Melting ice sheets discharge large volumes of water and sediments, and with them, release previously overridden organic and inorganic matter to glacial margins and oceans. This released material takes many forms (e.g. nutrients, heavy metals, greenhouse gases), but our current scientific understanding on how it directly or indirectly impacts surrounding environments remains very limited. This leaves it unclear how future ice melt will affect oceans and the global climate beyond sea level rise and changing landscapes.
To close this knowledge gap, we aim to increase our monitoring of greenhouse gases, nutrients, and organic carbon released in glacial runoff and recently deglaciated areas in Greenland and Svalbard over a period of ten years. We are studying how the different compounds interact and investigating how they are cycled by microbes. We are modelling how these processes play out on a global level. Our goal is to produce the first reliable model of how nutrients and carbon in ice sheet forefields will affect the global climate.
