MAREANO-surveys in 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.

Multibeam surveys for bathymetric mapping

In the Norwegian Sea, the following areas will be surveyed in 2014: Sklinnabanken, Sklinnadjupet, parts of the shelf edge, and Stadhavet. The multibeam surveys in these areas will take place between May and October this year. In the Barents Sea, bathymetric mapping has continued throughout the winter due to unforeseen delays in 2013. The areas that were been put on hold are to be completed during May 2014. All areas are shown in the map below.

Biological, geological and chemical sampling

Three surveys are scheduled this year to conduct biological, geological and chemical sampling.The first cruise will kick off on April 13, when the research vessel G.O. Sars will leave the city of Tromsø in Northern Norway. Sampling will be carried out off the coast of Finnmark, the northernmost  Norwegian County, and in the new areas along the Russian/Norwegian border (see figure below). This survey will end on April 26. However, sampling in these northern areas will resume on August 18, finishing on September 4.

A third survey, this time with the research vessel Johan Hjort, will take place from June 16–26, and will head to the shelf edge just northeast of Mørebankene in the Norwegian Sea – to an area named Storneset. Regarding seabed sampling in 2014 MAREANO will have 44 survey days in total.

Survey participants

In addition to the regular crew aboard the research ships, the MAREANO staff comprises 12 scientists and technicians from the Geological Survey of Norway (NGU) and Institute of Marine Research. The MAREANO staff includes geologists, biologists, chemists, computing/GIS-experts, and instrument engineers. Guest-researchers from the Maritime Museum/Aquarium in Gothenburg and Bergen Museum/University of Bergen will also join parts of the MAREANO surveys this year.
