Cruise CAGE18-4 with UiT’s research vessel R/V Helmer Hanssen was carried out to collect cross-disciplinary data for addressing the objectives of the Norwegian Centre of Excellence for Arctic Gas Hydrate, Environment and Climate, CAGE. The cruise was split into two legs with a port call in Longyearbyen. Leg 2 continued our investigations of the newly discovered gas seepage field in the Leierdjupet Fault complex (see CAGE17-3 cruise report) focusing on a better understanding of its complex leakage and source-to-sink plumbing system using seafloor photo and video imagery, water and sediment sampling, multibeam mapping and hydro acousticsOperator who enters this information

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 13:54:36 +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, cruise_name, harbour_from, harbour_to, platform_class, srs, abstract, filesize, in_gridding, weight, gridding_resolution, qi_horizontal, url)
