2Abstract
The main goal of CAGE 17-2 AMGG cruise was to study the gas-hydrate-bearing system and methane emission off south and east of Spitsbergen in Storfjordrenna and the northern flank of Olga Basin (named here Olga craters) respectively, and in the West Sentralbanken. We addressed this through a comprehensive scientific program comprising dives with the MISO-Tow Cam adapted to the multicorer frame from UiT-NPI (TowCam/Multicorer, TCM), methane measurements in sediments, water column, and in air, sediment coring (multicorer + gravity corer), water column and sediment biogeochemistry, microbiology, micropaleontology, and bathymetric mapping. Cruise CAGE 17-2 was also hosting this year’s AMGG research school cruise with masters, PhD and post-doc students participating.URL

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)
