Abstract
The aim of the cruise was to visit two study areas: the first a new study site called Maud Basin in southern Bjørnøyrenna – an area where industry data has shown promising evidence for gas leakage associated with pingo/crater formation and an underlying hydrocarbon reservoir. The second site is the Crater Area previously visited by CAGE in 2015 (15-5). More specific objectives of the cruise were to: obtain multibeam and seismic lines over pingos and craters in Maud Basin, southern Bjørnøyrenna, already identified on industry seismic data, re-examine the high density flares areas of the Crater Area previously surveyed in 2015 for any changes, survey new areas in the surrounding region of the Crater Area, and obtain plankton net data from gas leaking sites for analyses of biomass.

Updated status to done after final check, changed weight of dataset.

Version 5

Tue, 19 Sep 2023 14:01:24 +0200

Updated status to finalising, corrected some metadata.

Version 4

Tue, 04 Apr 2023 10:23:07 +0200

Added back into gridding after converting to correct resolution (300 m) in Qimera. Updated metadata (originator, provider, filesize, filename, weight, in_gridding, gridding_resolution).

Version 3

Tue, 21 Mar 2023 13:54:36 +0100

Removed from gridding due to incorrect dataset resolution.

Version 2

Mon, 13 Mar 2023 10:38:04 +0100

Data were cleaned of majority of outliers in Qimera and added to gridding. Updated or added metadata (name, filename, cruise_report, scientist, harbour_from, harbour_to, platform_class, instrument_specified, srs, abstract, filesize, in_gridding, weight, gridding_resolution, url)
