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)

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.

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.

Novel instrumentation

Sensor technology for ocean parameters is developing quickly in response to technical innovations and availability of autonomous platforms such as sea-gliders and profiling as well as static floats.
