Long-distance migration and venting of methane from the base of the hydrate stability zone
Marine methane hydrate is an ice-like substance that is stable in sediment around marine
continental margins where water depths are greater than~ 450–700 m. The release of …

Evolution of complex giant seafloor depressions at the northern Argentine continental margin (SW Atlantic Ocean) under the influence of a dynamic bottom current …
Seafloor depressions (SD) are features commonly observed on the ocean floor. They often
occur as circular, small-sized (up to 10 s of m) incisions caused by fluid expulsion. Larger …

Channel inception through bottom‐current erosion of pockmarks revealed by numerical simulation
In deep‐marine environments, the inception of channels can be induced by the interaction
between bottom currents and rough topography. However, it is still unclear under which …
