In the Marine Physics group, we study physical processes controlling the motion and properties of ocean waters and the influence it has on the marine environment as well as on the climate. Marine physics has a special place in marine sciences because of the strong control of physical processes on the biogeochemical environment extending from the coastal to open ocean. The ocean is an integral component of the weather and climate system and is currently experiencing rapid changes as the impact of anthropogenic activities on the climate increases. Large uncertainties on the fate of the Earth climate are associated with our (lack of) knowledge about the ocean state, motivating broad research efforts in Marine Physics.
As any physical science, marine physics draws mainly on mathematics to build theories and models to represent the complex ocean system. Marine physics rely heavily on a combination of integrated observing systems (both satellite and in situ) and numerical simulations done on supercomputers to build a comprehensive picture of the ocean circulation and its variability.
These models can then be used to gain understanding on the physical ocean system and are central to the production of numerical weather predictions and of climate projections.
Currently, the Marine Physics group forms the biggest concentration of expertise in autonomous observing platforms in Sweden, operating an Autonomous Underwater Vehicle (AUV, link), several Sea Gliders (link) and deploying animal-borne ocean sensors (link).
These instruments are used to extend the reach of conventional observing systems in poorly-known regions such as the Southern and Arctic oceans, or in coastal areas. Activities in marine physics include as well a strong numerical modelling component, running regional and global ocean models to facilitate interpretation of observations and learn about the main driving forces controlling ocean properties.
The Marine Physics group is involved in a large variety of research efforts and international programs, and contributes to the lively academic environment of the seafaring city of Gothenburg (link).
