Biography

PhD Project title:

Benthic faunal response to sub-seabed methane emissions offshore Svalbard.

PhD Project description:

Sub-seabed emissions from gas reservoirs provides the potential for chemosynthetically fueled ecosystems to form. Few studies have documented influence of submarine gas release in the Arctic and this project aims to examine the biological macrofaunal response, community structure and function from sub-seabed gas deposits. The project is part of CAGE (Center for Arctic Gas Hydrate, Environment and Climate) whose primary aim is to understand sources and sinks of methane from sub-seabed reservoirs to the atmosphere in perspective of Arctic climate change.

Start date: April 2014
Planned submission date: April 2018
