English summary

Sammendrag

The report gives an overview of cruises in 2018, by the Institute of Marine Research and University of Bergen, on board our research vessels and hired commercial vessels. Each cruise is described by a short description and a track chart mainly showing CTD, plankton and trawl stations. The coverage of the oceanographic sections is listed in a table. Another table shows the number of observations per month for the fixed stations. Meta data about the cruises are reported to the International Council for the Exploration of the Sea (ICES) using the form “Cruise Summary Report”: http://www.seadatanet.org/Metadata/CSR. Research data are available from the Norwegian Marine Data Centre at Institute of Marine Research. The charts can internally at IMR be downloaded from the Institute Intranet/Archive. Charts are made by Karen E. Gjertsen. Sebastian Bosgraaf made charts for “G.M.Dannevig”.

20186710	26.9.-20.10.	This cruise is part of the Nansen Legacy project and the research focus 1 (RF1) “Natural drivers”, subtask T1-3.1. RF1 aims to improve our understanding of the physical climate system in the Barents Sea and adjacent Arctic Basin. Subtask T1-3.1 will investigate the natural variability and ranges of sea ice cover and Atlantic Water through flow in the Barents Sea. The Barents Sea and Arctic climates in general comprise a strong component of natural variability. For any attempt to project and predict future changes in this environment, it is important to understand the range of this variability, its evolution over time, and its responsiveness to external drivers. The paleoclimate records provide this strongly needed insight and will enable assessment of the changes associated with prior intervals where sea ice cover was less and temperatures were higher than those experienced in the recent past were when instrumental and observational records were obtained.

2018816	14.3.-27.3.	“Svalbard”	The main purpose of the cruise was to obtain data necessary for estimation of the abundance of harp seals and hooded seals, of the Greenland Sea stocks. The methodological approach implied conduction of aerial surveys of harp and hooded seal pups in the Greenland Sea pack-ice during the whelping period in 2018. One fixed-wing twin-engined aircraft (stationed in Akureyri, Iceland) was used for reconnaissance flights and photographic surveys along transects over the whelping patches once they have been located and identified. A helicopter, stationed on and operated from the vessel (KV “Svalbard”), assisted in the reconnaissance flights, and subsequently flew visual transect surveys over the whelping patches. The helicopter was also used for other purposes (stageing of pups, monitoring of ice drift). In addition to serve as base for the helicopter surveys, the vessel was also used to transport personell into the whelpimg patches where some ground-truthing of the aerial surveys and collection of biological samples were performed.

Samples for analysis of the levels of pollution in the sediments were collected. The samples will be analysed according to the OSPAR guidelines for monitoring the petroleum industry. Multi beam Eco-sounders will be used to fill gaps in our available bathymetric maps of this area. Hydrographic measurements and water sampling took place along the sailing route. Plankton, fish larvae and micro plastics were collected along the sailing tracks by use of a ship mounted Cufes pump that delivers 1,7 m2 from 2 meters depth.
