Expedition diary: After sailing for 33 hours from Tromsø, we are approaching Spitsbergen Bank, which is well-known as a highly productive sea area between Bear Island and Hopen. We will also be surveying an area called Kirkegården (“the churchyard”), although no-one on board is sure how it got that name.

28.05.2021

Researchers on a MAREANO-cruise found a wreck off Bodø that they assume must be DS Malmberget. After 108 years, we may be close to solving the mystery of this ship, which disappeared in a storm with 43 people on board.

Current events at Aktivneset

27.04.2021

Cruise diary: After 16 hours transit from Garsholbanken, we arrived at a new sampling area, west of Aktivneset. This place is special as it is located at the outer part of the Norwegian Channel, a channel that starts south of Oslo and curves around Norway, before reaching Aktivneset.

Cruise diary: The ongoing MAREANO survey has now moved southwards from the Træna Bank to the Sklinna Bank on the mid-Norwegian shelf. The seafloor terrain here varies more than farther north, and we have found hitherto unregistered cold-water coral reefs.

Seabed mapping in the Norwegian Arctic

05.11.2019

Thursday afternoon, on the 10th of October, RV G.O. Sars left Tromsø harbour, heading for Kvitøyrenna, a bathymetric trough located between the islands Storøya and Kvitøya within the eastern part of the Svalbard archipelago. It is a long way from Tromsø to Kvitøya, and the transit was planned to take two and a half day. However, the trip took even longer when a northerly wind picked up.

MAREANO is currently on cruise gathering visual and physical seabed samples from several areas around the Svalbard archipelago in the Norwegian Arctic. At the moment we are back in outer Kongsfjordrenna trough, offshore of northwest Svalbard, after a couple of days working closer to shore in Kongsfjorden due to poor weather. Here we tell you a little bit about what we have seen here.

New general biotope map for the Barents Sea

24.10.2019

Mareano has now published an updated general biotope map for the Barents Sea. This map more than doubles the area for which biotopes distribution has been predicted in this area, and provides the first indication from Mareano results of distinctive habitats occurring in Arctic waters and north of the Polar Front.

Testing Autonomous Mapping

01.07.2019

New sensor platforms, such as autonomous vehicles and drones, open up new possibilities for mapping the terrain, sediments and habitats in shallow waters and the foreshore. In June MAREANO teamed up with NTNU-AMOS to test out unmanned and autonomous platforms for interdisciplinary mapping.

New Nautical Chart on Svalbard

27.06.2017

A new chart covering waters north of Nordaustlandet, has been published. This main chart is named “no. 541 Nordporten–Sjuøyane”. MAREANO and the Norwegian Mapping Authority Hydrograophic Service surveyed the fairway to Rijpfjorden in 2016.

Mud Stars are important as they burrow down into the mud, helping to oxygenate the sediment and stimulating microbial growth, which contributes to nutrient cycling and release. They also feed on the organic matter present within the mud, hence the name Mud Star.

Leaders of the Mareano Programme Group and the Executive Group hands over the baton

13.06.2016

During last week there was a change in leadership within the Programme Group (executive heading) of Mareano when Signe Nåmdal (Norwegian Environment Agency) replaced Aksel Eikemo (The Directorate of Fisheries). The group has the superior responsibility regarding implementation of the different activities in Mareano. Also the Executive Group (doing the daily operations in Mareano) did alter its leadership and here Sten-Richard Birkely took management in the group replacing Børge Holte (both from the Institute of Marine Research).

MAREANO's 2016 field surveys in the Barents Sea and around Svalbard

31.05.2016

MAREANO's 2016 campaign of hydrographic surveying began in February mapping the area between Bjørnøyrenna and Sørkapp, on Svalbard. Later this year bathymetric data acquisition will continue in the Barents Sea at the Norwegian side of the agreed Delimitation Line between Norway and Russia. Bathymetry data will also be acquired along the north coast of Svalbard, starting this year with surveys of the passage to Rijpfjorden. During 2016 there also will be two cruises for geological, biological and chemical sampling. The first cruise starts in June and will sample the new Norwegian area adjacent to the Norwegian/Russian Delimitation Line. The second cruise is bound for the area from Bjørnøyrenna to Kong Karls Land, to the southeast of Svalbard, and will be conducted in September – October.

Mission Accomplished — yet another successful cruise!

09.09.2015

Cruise diary: During the course of two weeks the biology and geology was mapped at 73 locations along the shelf edge west of the town Sandnessjøen at depths ranging between 220 and 760 meters. At 14 of these sites, a total of 83 bottom samples were collected using grabs, cores, sleighs, and beam trawls. At all sites the seafloor was investigated and documented using the Chimaera video rig (Chimaera is the Latin name for the rabbit fish/rat fish).
