Hunting flares in Hopendjupet and glacigenic sediments in Sentralbankrenna (20.2)

Introduction

The research cruise was part of the Centre of Excellence (SFF) Centre for Arctic Gas Hydrate Environment and Climate (CAGE) at UiT – The Arctic University of Norway. It was partly supported by The Norwegian Petroleum Directorate. From Tromsø, we visited Sentralbankrenna and Hopendjupet in the central Barents Sea in order to pursue the following scientific objectives:

– Identify gas seepage associated with known and assumed sandstone reservoirs sub-cropping at the sea floor.

– Identify gas seepage related to leakage along faults and geological structures breaching the seafloor.

– Collect gravity cores, multibeam and sub-bottom data to establish how grounding zone processes impact marine-based ice sheet behaviour and trigger ice-stream retreat during deglaciation.
