Biogeochemistry

Biogeochemistry is the science of the processes that govern the distribution of the elements throughout the Earth system. We focus in particular on those that control the transfer of elements between various environments. These are often related to climate, such as the uptake of CO2 by the land biosphere and the oceans, and to biology, for example the availability of nutrients in the ocean. Biogeochemistry is a highly interdisciplinary science, involving biology, chemistry, oceanography and geology, and deals with issues unfolding across several temporal and spatial scales. Our science relies on model simulations as well as field and experimental data. (Foto: Emil Jeansson)

Ocean currents determine CO2 uptake

That the ocean slows down global warming by absorbing CO2 from the air, is pure chemistry. But to find out how much, you have to know how the ocean moves. Friederike Fröb's PhD shows that both weather and ocean currents play a role.

Doctoral dissertation

The ocean breathes

Friederike Fröb defends on Tuesday, 27th of June 2017 her PhD dissertation at the University of Bergen with the title: “Climate controlled mechanisms of subpolar North Atlantic carbon uptake”.

Systematic combination of models with observations

The biogeochemical modules in the Earth system model NorESM (ocean: HAMOCC, originally developed at MPI in Hamburg, adopted in Bergen for isopycnic coordinates; land: CAM4, originally developed at NCAR) need to be systematically improved with respect to observations.

Time varying carbon sink and process attribution

A major result of the CARBOOCEAN and CARBOCHANGE EU projects, which the group coordinated / coordinates, was the finding that the ocean sink for human-produced carbon is undergoing remarkable changes on a basin-wide ocean scale on a timescale of only a few years.
