Research

active and past projects

The Experimental Oceanography group is part of the Earth System Sciences department at the Universität Hamburg. We aim to advance understanding of ocean dynamics and circulation in a changing climate. We are a seagoing group, specialising in physical oceanographic measurements and using approaches that leverage traditional observations with new platforms and satellite data.

Topics include:

  • Large-scale ocean circulation including the Atlantic meridional overturning circulation and gyre circulations.
  • Small-scale processes, e.g. deep ocean convection, submesoscale mixing, and turbulent dissipation.
  • Measurement methods. Using in situ and remote sensing to better observe the ocean.
