Research on oceanographic processes

There are many important processes that are parameterized or not fully resolved in large-scale oceanographic and biogeochemical models. The research group on oceanographic processes investigates these with the aims of increasing the understanding of small-scale processes, and improving parameterizations.

The group works mainly with research and analysis of small scale processes that regulate trends, transports, and fluxes of water and substances in the marine system. This is done with a combination of models, observations, and theoretical and statistical analysis methods.

The work aims towards enhanced understanding of the most important processes in the ocean, and the sensitivity of the marine system to changes caused by climate change and other anthropogenic effects. The group helps improving existing model tools, pushes the use of higher-resolution modeling tools, and supports the development and use of new measurement techniques. In addition, the work aims at improving the connection between observations and models, and the flow and analysis of data.

One example of focus areas is transports and spreading of substances, such as toxins, harmful algae blooms, nutrients, ballast water, etc., within semi-encloses coastal waters as well as between these waters and the open sea. Another focus area is the representation of straits and topographic features in medium-to-low resolution models. Vertical transports of dissolved matter and gases between the sediments and the water, between the water and the air, and between layers of different densities in the water column are also potential subjects of interest.
