Abstract
The cruise had the following scientific objectives: geomorphic mapping of seafloor features at the Yermak Plateau as far north as possible aiming at identifying ice flow orientations, improve the seismic stratigraphy along the western Svalbard continental margin using the ODP holes 910C and 912A of the Yermak Plateau and the ODP hole 986 west of Svalbard, and investigate fluid-flow features related to gas hydrate bearing sediments.

Version 5

Tue, 19 Sep 2023 14:01:24 +0200

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)
