Surrounded by corals

05.06.2015

A number of different coral reefs have been discovered in waters off the Norwegian coast. The Røst Reef off Norway’s Lofoten Islands is the world's largest known Lophelia reef. That these corals almost encircle the entire North Atlantic is more unknown.

Cruise diary: This newsletter has been written by all the biologists onboard the G.O.Sars at the last biogy and geology cruise in 2014. Each biologist has picked her favourite photo from the work on this cruise, and they have written a story for that picture.  There are many different voices here, this reflects both the diversity we see in the benthic communities – and the diversity among the biologists.

New glider in the Barents Sea

03.09.2014

Cruise diary: The Mareano 3 cruise also includes deployment of a new type of underwater glider - a 'SeaExplorer' - to complete a north-south transect of the Barents Sea. Two guests from the LOCEAN laboratory in Paris are on board the G.O. Sars for the deployment: glider engineer Michael Field and PhD student Laurent Oziel. The SeaExplorer was successfully deployed from the rescue boat on 2 September.

How to use the uw-camera

08.07.2014

The MAREANO cruise was undertaken to survey the sea floor at Storegga, Norwegian Sea. In order to achieve this we took a multitude of video stations coupled with a few beam trawls, RP nets, grabs and cores.

The incredible world of Storegga

25.06.2014

Last autumn MAREANO scientists documented the geology and biology of the southern part of Storegga, which lies at the edge of the continental shelf in mid-Norway. Now we are back to complete the journey through this fascinating underwater landscape, armed with new multibeam data that complete the picture of the terrain on the shelf.

On their way to the depths

18.05.2014

VIDEO: During the MAREANO-survey April 13–26 a large number of king crabs were observed at about 40 m depth just off the village Berlevåg in the northernmost Norwegian county Finnmark. It is well-known that the king crab thrive in this area and was on its way towards deeper waters after a short trip to quite shallow depths where hatching, spawning and mating take place at this time of the year.

MAREANO-surveys in 2014

08.04.2014

In its tenth year, MAREANO is to survey both the Norwegian and the Barents Sea. Bathymetric measurements in the Barents Sea have been undergoing since January along the Russian-Norwegian border while the 2014 start-up in the Norwegian Sea took place in March. The biological, geological and chemical sampling will start on April 13 off the coast of Finnmark and in the south-eastern part of the Barents Sea, and on June 16 in the Norwegian Sea, northeast of Mørebankene.

Carbonate crust revealed in pockmarks on the mid-Norwegian shelf

29.01.2014

Video footage acquired during MAREANOs latest cruise at Skoldryggen has revealed why the inside of pockmarks at 440 m depth on the seabed appear harder than the surrounding seabed, when seen on multibeam backscatter images. Carbonate crusts have been found at the bottom of the pockmarks (Figure 1).

Biotopes of the mid-Norwegian continental shelf revealed by MAREANO

09.12.2013

A biotope map for the Norwegian Sea based on video data from MAREANO 2012 is now available on www.mareano.no. Biotopes are regions with similar communities of animals living on the seabed, in a similar physical environment. Maps such as these, which bring together the physical and biological attributes of the seabed, can provide particularly valuable information for sustainable management.

Biotope map for Nordland VI published

05.12.2013

MAREANO scientists have now produced a biotope map for the Nordland VI area in Northern Norway. "Biotope" is a term used to describe the main biological communities and the physical environment they inhabit.  MAREANO video data were to determine the biological communities and this information was put together with bathymetry, terrain and geological data to model the overall distribution of biotopes.

More vulnerable seapens discovered

27.09.2013

Two new areas with high concentrations of seapens have been documented in the Barents Sea, near the coast of the county of Finnmark. Once we have analysed our videos of these areas, we will know whether the concentrations are high enough for both areas to be defined as vulnerable under the international OSPAR Convention. The videos were taken during the expedition that we completed in August.
