Abstract
The cruise was part of the Centre of Excellence (SFF) Centre for Arctic Gas Hydrate, Environment and Climate Climate (CAGE) at UiT – The Arctic University of Norway. It was partly supported by The Norwegian Petroleum Directory (NPD). The cruise had the following scientific objectives: identification of gas seepage associated with assumed hydrocarbon reservoirs subcropping the sea floor due to erosion of overlying cap rocks, identification of gas seepage related to leakage along faults breaching the seafloor, acqusition of multibeam, subbottom profiler, seismic data and samples of gas in water and sediments for cross disciplinary investigations by CAGE, and deployment of seafloor observatory and oceanographic studies west of Prins Kars Forland.

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, scientist, harbour_from, harbour_to, platform_class, srs, abstract, filesize, in_gridding, weight, gridding_resolution, qi_horizontal, url)
