Despite a large number of studies, a detailed overall picture of benthic communities zonation in the Arctic fjords is currently lacking. Our study aimed to find out whether there is a universal model for the distribution of benthic communities based on the structural features of the fjords. We examined benthic macrofaunal communities in fjords with...

Human expansion to the sea gathers pace and so does the diversity of new substrates exposed to biofouling. Various subsea production structures often serve unintentionally as artificial reefs attracting dozens of fouling species. In this presentation we are showing what a 10-year-old succession in a biofouling community on the subsea production com...

Biofouling of artificial substrates is a well-known phenomenon that can negatively impact offshore industry operations as well as data collection in the ocean. Fouling communities worldwide have mostly been studied within the top 50 m of the ocean surface, while biofouling below this depth remains largely underreported. Existing methods used to stu...
