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.

Living in a landslide

15.10.2013

Cruise diary: MAREANO is currently mapping the southern part of Storegga, along the shelf edge and slope areas where a series of underwater landslides have occurred, most recently the famous Storegga slide, which dramatically altered the underwater landscape here some 8200 years ago.

In deep water off Mørebankene

07.10.2013

The last piece of the bottom areas on and around Mørebankene are now surveyed by MAREANO after two weeks work aboard the research ship G.O. Sars (see sampling stations in the map below). A varying benthic fauna living within old avalanches and on plains has been videotaped and sampled. The rate is now set for the waters off the coastline from Kristiansund to Haltenbanken.

MAREANO's autumn cruise is underway

27.09.2013

Cruise diary: On Sunday 22nd September the research vessel G.O. Sars sailed from Kristiansund to begin MAREANO's third cruise in 2013. During this cruise several areas off the coast of Møre and Trøndelag in mid-Norway will be documented using underwater video and various equipment for sampling the seabed.

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.

Barents Sea South East – mother nature’s pantry

27.09.2013

Cruise diary: The MAREANO project has mapped one of the most bountiful parts of the Barents Sea, finding that the sea bottom is covered in iceberg plough marks from the last ice age, large rocks, pockmarks and a multitude of trawl marks. The latter reflect the large quantities of shrimp and fish harvested by the fishing fleet from this highly productive area.

Important Nordic marine science conference

05.09.2013

The Nordic Marine Science Conference 2013 will be held 28th - 30th October in Oslo, Norway, with the title "Marine ecosystems in a changing environment". There will be a strong focus on the effects of climate change - both in the physical environment and on the ecosystems. These topics are getting increasingly important in MAREANO.

MAREANO expedition ahead of schedule

27.09.2013

Cruise diary: Good weather means that the MAREANO expedition is now ahead of schedule, and all of the programmed sites have been surveyed. The “G.O. Sars” has therefore set sail for the coast of the county of Finnmark (the “Finnmark East” area), in order to survey some additional sites there on the last days of the expedition.

A seabed full of pockmarks

12.08.2013

The second MAREANO cruise in 2013 maps the seabed along the Russian border in the Barents Sea. Over large parts of the Barents Sea, the seabed is full of pockmarks. The processes that create pockmarks are important for both fauna and climate, and the ongoing MAREANO cruise will provide data that will contribute to resolving questions related to these.

Can we find gold in mud?

25.06.2013

Cruise diary: MAREANO often writes cruise-reports about all the beautiful and exciting things we observe with out video-rig. This is of course a very important part of the MAREANO-programme, and much of our cruise-time is allocated to filming our videolines. These data are the backbone in our descriptions of nature types, and they are the basis for our maps (e.g. maps of vulnerable nature types). But don’t believe that all we do on a cruise is to sit in the dark videoroom watching the sea-floor. We sample using quite a lot of other methods as well!

Coral reefs at Skjoldryggen

25.06.2013

Cruise diary: June 19, after half of the planned stations at Skjoldryggen was covered (30 video locations of which seven were also bottom sampling stations), the first leg of the cruise ended in Kristiansund. We have seen small dead coral skeletons (coral rubble) at several locations when using the video-rig Campod. Then, we have most likely passed reefs in their outskirts.

Sampling of seabed sediments on Skjoldryggen, mid-Norway

25.06.2013

Cruise diary: During the first leg of this summer’s first MAREANO cruise we have been sampling seabed sediments in the northern part of Skjoldryggen, on the mid-Norwegian margin. Skjoldryggen is a large terminal moraine deposited during the last glaciation, when the Scandinavian ice Sheet extended to the edge of the continental shelf. It is about 65 km long from north to south, up to 6 km wide and 100-150 m high.
