Assimilation of heterogeneous measurements at different spatial scales in the Arctic ocean and Norwegian sea

The assimilation of ocean temperature measurements into ocean models provides useful insights on how to design heterogeneous ocean observation systems. This study demonstrates how to best complement models with operational assets such as satellites etc.

Twin experiment analysis of data assimilation performance using Gaussian anamorphic transformation for highly skewed ocean model variables

This study investigates the use of Gaussian anamorphic transformations to assimilate non-Gaussian biological state variables in an ensemble Kalman filter framework.

Campaign For Hyperspectral Data Validation In North Atlantic Coastal Waters

The high photosynthetic productivity of the Mausund bank on the coast of mid-Norway has given the area important economic and ecologic value. Monitoring chlorophyll-a (chl-a) production can assist in managing the local aquaculture and ecosystem.
