||The northern North Atlantic and its adjacent Nordic Seas and Arctic Ocean and are key areas for understanding the climate on Earth. This is one of the few places on Earth where relatively cold, salty waters sink to the abyss, forming the so-called North Atlantic Deep Water and propelling a system of global ocean circulation - the meridional overturn. This circulation is closely linked to the strength of the Gulf Stream and the North Atlantic Drift. Changes in this strategic region can - and have - lead to widespread and abrupt climate changes.
My interests here lie with
- the flow of deep waters through the "bottle neck" of the Faero-Shetland Channel
- deep winter convection and its impact on carbon transport to depth
- the sub-polar gyre, how it modulates the seasonal pattern of primary production
- how this seasonal pattern impacts higher trophic levels, from zooplankton to fish and sea birds.
