Sammendrag

This cruise (onboard the RV G.O. Sars, 30.03.2023 to 12.04.2023 - 13 Days long starting and ending in Bergen, Norway) was focussed on surveying the coastal belt east of “Utsira Nord” (Utsira KB) and the two multibeam mapped areas close to “Sørlige Nordsjø II” (NSJ-1 and NSJ-2). These areas are of interest due to their proximity to the named offshore wind license areas and due to their overlap with “særlig verdiful områder” (SVO) which are areas of particular scientific and management interest.

The MAREANO baseline mapping method was applied, but this cruise was focussed upon completing the video lines in these areas, and testing the munin+ AUV for data uses and the integration of AUVs into the Mareano method. In addition, the Oil Directorate asked for 2 gravity cores from areas with suspected natural oil leakage, and limited physical sampling equipment was taken for contingency use.

One hundred and twenty reference stations were visited including completing 112 (225m long) video lines, along with 5 AUV missions (collecting EM2040, HISAS2040, SBP, CT, photo data). Furthermore, 8 CTDs, 5 Boxcores, 4 Multicores, 2 stations with grabs for checking if the gravity corer can be used (no proposed site had suitable substrate for gravity coring), and 2 stations with 5 replicate grabs each for biology/geology were completed. Topaz subbottom profiling (SBP) data was collected along and between video lines and all gravity corer proposed sites, with additional water column multibeam echosounder (EM302) data also collected over all the proposed gravity corer sites. Note that 3 video lines, 1 AUV mission and 2 CTD sites were within the fjords near stavanger (during poor weather) in areas where FOH granted declassificaiton for AUV activities.

1 - Abbreviations

The following Abbreviations are use throughout this report:

 

AUV: Autonomous Underwater Vehicle – here it is the Kongsberg Munin +.

CT: Conductivity and Temperature (but not Depth as is normal) – the AUV CT sensor does not collect pressure information that is converted into depth as standard, but it does have an altimeter/depth sensor as part of that navigation system so this data is also available.

CTD: Conductivity, Temperature and Depth sampling rosette

GC1, GC2, etc: Gravity Corer station where there had been requests from the Oil directorate to take gravity corer samples if possible. No sites had suitable sediment to take these samples in the end but the sites are still locations where sampling took place so are logged here.

HI: HavforskningsInstituttet or the Institute of Marine Research as it is called in English.

MBE: MultiBeam Echosounder

NGU: Norsk Geologiske Undersøkelse or the Norwegian Geological Survey as it is called in English.

NSJ-1; NSJ-2: Nord Sjø mapping areas, ames assigned by Mareano but often informed by industry mapping names such as the Sørlige Nordsjø II area which is the official name assigned to an offshore wind licensing area.

SVO: Særlig Verdiful Område – translates to “Especially Valuable Area” and is a Norwegian management region that currently has no protection measures but indicates an area of particular ecological value.

Utsira KB: The Ustira Kyst Belt – another Mareano mapping area name. Utsira is an island in the area and Norway’s smallest municipality.

 

2 - Aims

  • Apply Mareano method, generally following the 30 stations/1000 km2 rule (for SVO/very variable environments), with a focus on Video sampling (using the Chimera towed camera rig).

ACHIEVED

  • Test AUV (Munin +) for data uses and integration into the Mareano method.

ACHIEVED

  • Take 2 x gravity cores at the request of the Oil Directorate in areas with possible natural oil seepages.

CHECKED SITES WITH TOPAZ AND GRABS, NONE SUITED TO GRAVITY CORERS/ SHOWING CLEAR EVIDENCE OF OIL SEEPS, ADVISE RETURNING WITH VIBROCORER

  • When there are issues with Chimera/AUV take Boxcores, Multicores, Grabs (in that order) at proposed full stations to reduce the load on the summer cruise.

SOME SAMPLES TAKEN AT FULL STATIONS (DETAILS FOLLOW)

3 - Areas

Overview map highighting where the Utsira KB and NSJ-1 and NSJ-2 areas are situated relative to the coast of norway and relative to offshore wind license areas (Utsira Nord adjoins the west of Utsira KB, Sørlige Nordsjø II adjoins SW of NSJ-1) and overlapping SVO areas
Figure 1 Cruise focus areas (Utsira KB, NSJ-1, NSJ-2) with reference to nearby offshore wind licence areas and proposed and existing SVO

This cruise was focussed on:

  • Utsira KB = The coastal belt east of Utsira Nord offshore wind license area (including within the Kystebelt SVO), and

  • NSJ-1 and NSJ-2 areas = Multibeam mapped areas which sit alongside the Sorlig Nordsjo II offshore wind license area and overlap with the Tobis SVO and a small corner of the Norskerenna proposed SVO.

  • A small amount of additional sampling was performed in Fognafjorden (one of three sites in the fjords around Stavanger where we had applied for, and received, permission from FOH for declassification of the seabed) as a bad weather retreat area where AUV testing could continue while waiting for improved conditions. A CTD was also taken at a second site closer to Stavanger, but that area had too much fishing gear in the way to proceed with AUV/video surveys.

6 - Collected Data

Infrmation about the data collected is here shown in the form of overview maps and a table of stations. More details are available in the day by day overview appendix or can be given upon request. 

An overview map of the cruise route is shown encompassing the south of Norway from Bergen in the north to the NS1 and NS2 areas that border the Danish EEZ.
Figure 2 An overview map showing the route of the cruise: Bergen, Utisira KB, NSJ1, NSJ2, Utsira KB, Fognafjorden, Utsira KB, Bergen (zoomed in maps of subareas follow)

The following maps show the overview of the route of this cruise and the sampling stations. A table follows showing all stations, data types collected there and a short description of what was seen on video lines.

 

 

Zoom in on the Utsira KB area of the map showing the zigzagging route of the cruise overlapping the multibeam data with stations labelled with R numers and symbols showing what type of data was collected there.
Figure 3 The Utsira Kyst Belt area showing reference station numbers sampled on this cruise (the numbering shows the order we visited them, starting at 3188-3200, then 3255-3301 excluding 3288-3290). Repeat visits to the area outside of 12nm were required for AUV testing.

 

 

Zoom in on the NSJ-1 and NSJ-2 areas of the map showing the zigzagging route of the cruise overlapping the multibeam data with stations labelled with R numers and symbols showing what type of data was collected there.
Figure 4 NSJ-1 (the larger area, reference stations 3201-3247, but excluding 3202 which is in the Sørlig Nordsjø II area and will be sampled in the future, here visited to check for the possibility of gravity coring with only a single grab sample taken) and NSJ-2 (smaller area, reference stations 3248-3254).

 

 

Zoom in on the Fgnafjorden area of the map showing the zigzagging route of the cruise overlapping the multibeam data with stations labelled with R numers and symbols showing what type of data was collected there.
Figure 5 On our second visit to Utsira, poor weather sent us inshore near Stavanger to Fognafjorden (the plan B weather retreat area where FOH approved the declassification of the seafloor for AUV testing. The plan A area in Horgefjorden, see inset, was checked but had too much fishing gear, marked by floats, to have confidence that we could launch the AUV or chimera safely) showing the AUV survey area where we have complete data (some was lost at the end of the mission, not marked), and the three Chimera video lines (R stations 3288-3290) – again other sites were prioritised in the NE but we found too much fishing gear in the way.
