The lower shoreface, defined here as between about 8 and 20 m water depth, forms the
transition between the inner shelf and upper shoreface. Knowledge of lower shoreface …

Geological structure changes, including deformations and ruptures, developed in shallow
marine sediments are well recognized but were not systematically reviewed in previous …

Marine sediments host large amounts of methane (CH4), which is a potent greenhouse gas.
Quantitative estimates for methane release from marine sediments are scarce, and a poorly …

High-resolution bathymetric data were collected with a multi-beam echosounder in the
southern part of the Baltic Sea (region MET1, Gulf of Gdańsk) revealing the presence of a 10 …

Pockmarks, intriguing seafloor geological and geomorphological features, are commonly
observed in marginal basins with hydrocarbon potential. As a Cenozoic marginal sea, the …

Pockmarks are concave depressions on the sea bottom produced by fluid escape from
subaqueous sediments which can be found worldwide in muddy and silt/clay sediments …

Seep carbonates tell us where and when CH 4-charged fluids escaped from the subsurface,
thus providing qualitative information to reconstruct the activity of petroleum systems. The …

Pockmarks are geohazards that can impact offshore developments, and an understanding of
their formation assists in determination of their physical characteristics and in the prediction …

Seabed pockmarks are among the most prominent morphologic structures in the oceans.
They are usually interpreted as surface manifestation of hydrocarbon fluids venting from …

Shallow gas is generally extensively distributed in the Holocene muddy sediments and gas
seepage has been increasingly reported to induce geohazards in coastal seas, but controls …
