Temperature simulation

Oscillations of a temperature interface between warm Atlantic water and colder, deeper water masses in the Ormen Lange area of the Nordic Seas. The bottom of the ocean is shown in grey. The 5.5 degree interface (shown in green) is interacting with the continental shelf slope outside mid-Norway, creating both strong currents and enhanced mixing near the sea bed. The arrows at the vertical wall in the deep ocean indicate current speed and direction. The computations are performed with the Bergen Ocean Model (BOM), see www.math.uib.no/BOM/.

The research performed by the Hydrodynamics group is connected with important geophysical, environmental, climatic and industrial issues.
For an overview of hydrodynamics, see http://en.wikipedia.org/wiki/Fluid_flow.

Work carried out by the Hydrodynamics group is performed in close collaboration with other specialists in Norway and internationally. In particular, in the Bergen region this research group collaborates with the Geophysical Institute, Uni Research (see http://www.bccs.uni.no/units/cmu/), the Institute of Marine Research, the Nansen Center, NIVA, and Statoil ASA.

In recent years, the study of internal waves (such as waves that propagate along the interface between different fluid bodies) has been central. These waves are challenging to study both theoretically and numerically. Furthermore, internal waves play an important role in the climate puzzle. When internal waves break, strong currents can occur at the bottom of the ocean that can affect industrial installations.

The Hydrodynamics group is also involved in research focused on CO₂ storage.
