Large national programs in the United States and several Asian countries have defined and
characterised their marine methane hydrate occurrences in some detail, but European …

Seismic and logging while drilling (LWD) data, gas hydrate samples, and hydrate gas
geochemical testing results acquired during the GMGS5 expedition in 2018 have been used …

Multiple proxies in the geological record offshore NW Svalbard track shallow subseafloor
diagenesis and seafloor methane seepage during the Last Glacial Maximum (LGM) extent …

Gas hydrate systems offshore western Svalbard are extensive and include the whole
Vestnesa Ridge, an elongated sediment drift north of the Molloy Transform and just east of …

The QICS controlled release experiment demonstrates that leaks of carbon dioxide (CO 2)
gas can be detected by monitoring acoustic, geochemical and biological parameters within …

Methane expulsion from the world ocean floor is a broadly observed phenomenon known to
be episodic. Yet the processes that modulate seepage remain elusive. In the Arctic offshore …

Focused fluid flow through sub-seabed sediments is a common phenomenon on continental
margins worldwide. However, the governing controls and timing of this fluid release have …

Contourite drifts are anomalously high sediment accumulations that form due to reworking
by bottom currents. Due to the lack of a comprehensive contourite database, the link …

We use new gas‐hydrate geochemistry analyses, echosounder data, and three‐
dimensional P‐Cable seismic data to study a gas‐hydrate and free‐gas system in 1200 m …

Ubiquitous observations of channelised fluid flow in the form of pipes or chimney-like
features in sedimentary sequences provide strong evidence for significant transient …
