Research topics

Important research topics of the marine biogeochemistry group are:

Observing the variable ocean carbon sink: The CO2 flux between the ocean and atmosphere, and ocean acidification, are quantified through measurements from research vessels, at time series stations and from commercial ships equipped with sensors. The biogeochemistry group at GFI plays a pivotal role in providing high-quality data syntheses for surface ocean CO2 and 3-D tracer distributions.

Climate change and tipping points: Observations and model simulations from the IPCC-class Norwegian Earth System Model (NorESM), are combined to understand, the effect of climate change on the marine environment, including acidification, deoxygenation, and ecosystem regime shifts.

Near-time predictions of ocean biogeochemistry: Mechanisms giving rise to interannual-to-decadal predictability of primary production and CO2 fluxes is studied with the Norwegian Climate Prediction Model (NorCPM).
