Physical Oceanography

Physical oceanography encompasses observations and the dynamics of the ocean. The Oceanography Research Group at the Dept. of Geosciences focuses on the dynamics of large-scale flows such as the Gulf Stream and the Meridional Overturning Circulation, as well as circulation in high-latitude regions. We also study turbulent dispersion, which is relevant for the spreading of pollution such as plastics.

About the group

The ocean is studied by collecting observations, running numerical models and by constructing simplified theories. The oceaography group is primarily focused on interpreting observations and complex model results in terms of simplified theory.

The term "Oceanography" derives from the Ancient Greek words ōkeanós 'the great ocean' and graphikos 'writing'.

Research topics include the dynamics of the Gulf Stream, the Meridional Overturning Circulation, and high latitude flows in the Arctic and Southern Oceans and along the Norwegian coast. We also study turbulent dispersion, to diagnose oceanic transport.

We employ models of varying degrees of complexity, from idealized mathematical models (“theory”) to full complexity Earth Systems Models. We also employ a range of ocean observations, from surface drifters and subsurface floats, long-term current meters, satellites and from ship campaigns. As such, physical oceanography allows students to develop math and computational skills while gaining understanding of a key part of the climate and ecosystem, globally and regionally.

The group has extensive collaborations with scientists in Norway and in other countries. These frequently involve research and education of PhD students and postdocs.

At present the following PhD students are affiliated with the research group for oceanography: Christine Kappatou and Anna Lina Sjur
