The Sea in Maps and Pictures

Cruise diary: An ordinary day at RV G.O.Sars begins, where biologists and geologists collect data for scientific mapping of the marine bottom habitats for the MAREANO program. During our inspection of the seabed with our towed video camera we notice some large bivalves, half-buried in the sediment between the cobbles and boulders.

Cruise diary: This MAREANO cruise marks the first time for most of us – if not all, where we can work in T-shirts and shorts, and even sunbathe on deck during breaks. In this summer survey, MAREANO scientists will continue obtaining video lines and physical samples in the study area of Sørvest F. This cruise is a continuation of the 2024 winter cruise during which the sea was at times rough and unfavourable for the ROV, preventing us in obtaining many of our video lines.

Cruise diary: On the way to the potential offshore wind area Sørvest F, as part of MAREANO’s mapping programme, the research vessel G.O. Sars had a first stop at a site where previous investigations had indicated gas seepage from the seabed. Video footage confirmed the gas seepage and revealed spectacular bacterial micro-ridges.
