2Abstract
Cruise CAGE18-3 aimed at investigating methane seep sites by surface sediment sampling, sediment core sampling, plankton sampling and water sampling. The areas for investigation were the Barents Sea (Crater area), Storfjorden Trough (Pingo area),East Greenland Ridge (non-seep, for IODP-proposal) (Leg 1 and 2) and the western Svalbard margin, Vestnesa Ridge, Arctic Ocean and Prins Karls Forland (Leg 3) on R/V “Helmer Hanssen”. The scientific sampling was done within the framework of several ongoing projects at the Department of Geology, University of Tromsø: “CAGE -Centre for Arctic Gas Hydrate, Environment and Climate”-WP6: “Methane Release, Ocean Acidification and CO2” here under ocean acidification impact on marine calcifiers (planktic foraminifera and pteropods, methane seeping impact on ocean acidification and productivity, the state of the inorganic and organic biological pump from foraminifera, bottom water temperature change and impact on release of methane, living benthic microfauna studies from seep sites for geochemical investigations for calibrations for paleostudies.URL

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)
