Abstract
The research cruise was part of the Centre of Excellence (SFF) Centre for Arctic Gas Hydrate Environment and Climate (CAGE) at UiT – The Arctic University of Norway. It was partly supported by The Norwegian Petroleum Directorate. From Tromsø, we visited Sentralbankrenna and Hopendjupet in the central Barents Sea in order to pursue the following scientific objectives: identify gas seepage associated with known and assumed sandstone reservoirs sub-cropping at the sea floor, identify gas seepage related to leakage along faults and geological structures breaching the seafloor, collect gravity cores, multibeam and sub-bottom data to establish how grounding zone processes impact marine-based ice sheet behavior and trigger ice-stream retreat during deglaciation.

Revisions

Version 6

Tue, 19 Sep 2023 12:33:28 +0200

Updated status to inactive.

Version 5

Wed, 31 May 2023 10:58:01 +0200

Removed from gridding again due to depth offset issue, checking if correction is possible.

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 13:54:35 +0100

Removed from gridding due to incorrect dataset resolution.

Version 2

Mon, 13 Mar 2023 10:38:05 +0100

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

Knut and Alice Wallenberg Foundation (KAW) and Swedish Research Council (VR) financed the Oden multibeam system and the installation was financed by the Swedish Maritime Administration. The Oden expeditions were organized by the Swedish Polar Research Secretariat. This Mapping Repository is a part of the Bert Bolin Centre for Climate Research data archive.
