Fig. 1: Bathymetric map of Storfjordrenna gas hydrate mounds and core locations.
From: Distinct methane-dependent biogeochemical states in Arctic seafloor gas hydrate mounds
Storfjordrenna is located south of the Svalbard Archipelago in the red box on the regional map. GHM: gas hydrate mound, GC: gravity core, PC: push core, mbsl: meters below sea level. Black points show cores collected and first described in this study, while white points indicate cores described in previous studies (see Table S3 for a summary of porewater data available from Storfjordrenna). White polygons at GHMs indicate areas of seafloor gas release observed at the time of the cruise in 2016.
