Researchers from the Marine Biodiversity research group have participated in a cruise aiming to map the marine life of the bottom of the Sognefjord. This is the longest and deepest fjord in Norway; 205 km long and 1308 m deep, with a rich and diverse fauna.

Marine Biodiversity cooperates with the Institute of Marine Research, NIVA and the Bergen University Museum in the “Species and habitat mapping of the Sognefjord”, funded by the Norwegian Species Databank. The cruise is the first of several, marking the start of a two-year project.


The fauna of the Sognefjord is not very well known. Norwegian fjords are unique habitats with great variation in local conditions, meaning they can sustain localized populations of rare species. This is the first time that the Sognefjord is subject to a study with this level of detail, where traditional sampling methods as well as newer instrumentation and video transecting are employed.
