The Hydrate-01 Stratigraphic Test Well was drilled at the Kuparuk 7-11-12 site on the Alaska
North Slope in December 2018. Sonic log data provide compressional (P) and shear (S) …

Most marine gas hydrate systems follow a vertical pattern with hydrate overlying free gas.
Here we document the discovery of a gas to hydrate system in a horizontal sand layer in the …

Abstract The Formosa Ridge cold seep is among the first documented active seeps on the
northern South China Sea passive margin slope. Although this system has been the focus of …

The highest concentration of cold seep sites worldwide has been observed along
convergent margins, where fluid migration through sedimentary sequences is enhanced by …

Identifying gas hydrates in the oceanic subsurface using seismic reflection data supported
by the presence of a bottom simulating reflector (BSR) is not an easy task, given the wide …

Sub‐seabed fluid flow, gas hydrate accumulation and seafloor methane seepage are tightly
interwoven processes with implications for marine biodiversity, ocean chemistry and …

Previous margin-wide studies of methane seep distribution along the Cascadia Subduction
Zone indicate peaks in seep density within the landward limit of the of gas hydrate stability …

Methane release from hydrate systems has long been considered as one of the important
mechanisms for global carbon cycle perturbations and ocean acidification. Here, a …

The influence of cold seep methane on the surrounding benthos is well-documented but the
fate of dissolved methane and its impact on water column biogeochemistry remains less …

Abstract Woolsey Mound, located at Mississippi Canyon Lease Block 118 (MC118), is the
site of the Gulf of Mexico hydrate research consortium's seafloor observatory, where gas …
