Complex Eyed Pockmarks and Submarine Groundwater Discharge Revealed by Acoustic Data and Sediment Cores in Eckernförde Bay, SW Baltic Sea

Geochemistry, Geophysics, Geosystems, 2020
Submarine groundwater discharge into coastal areas is a common global phenomenon and is rapidly gaining scientific interest due to its influence on marine ecology, the coastal sedimentary environment, and its potential as a future freshwater resource. We

Seismic Characteristics of Paleo-Pockmarks in the Great South Basin, New Zealand

Frontiers in Earth Science, 2021
Globally, a wide range of pockmarks have been identified onshore and offshore. These features can be used as indicators of fluid expulsion through unconsolidated sediments within sedimentary basin-fills.

The Enigmatic Pockmarks of the Sandy Southeastern North Sea

Geochemistry, Geophysics, Geosystems
Natural seafloor depressions, known as pockmarks, are common subaqueous geomorphological features found from the deep ocean trenches to shallow lakes.

Characteristics, classification and genetic mechanism of pockmarks

地质科技通报, 2023
Pockmarks are a kind of negative geomorphology formed by overpressure fluid spilling from the seabed. They are widely distributed in various underwater tectonic environments (such as continental margin basins and accretion wedges).

Lacustrine Groundwater Discharge Through Giant Pockmarks (Lake Neuchatel, Switzerland)

Frontiers in Water, 2020
Pockmarks are circular depressions on the floor of oceans and lakes and constitute potential hot spots of gas ebullition and/or groundwater discharge. Marine pockmarks are well-studied, whereas lacustrine pockmarks are virtually unexplored.

Cyclic Pockmark Formation Linked to Plio‐Pleistocene Sea‐Level Rise on the Chatham Rise, New Zealand

Geochemistry, Geophysics, Geosystems
Pockmarks are geomorphological depressions on the seafloor in various underwater environmental settings. They are commonly linked to fluid release from subsurface reservoirs; however, the processes involved, fluid types, and relative timing of their ...

Pockmarks in the Witch Ground Basin, Central North Sea [PDF]

Geochemistry, Geophysics, Geosystems, 2019
AbstractMarine 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 constrained temporal variability leads to large uncertainties in methane emission scenarios.

Morphology, Formation, and Activity of Three Different Pockmark Systems in Peri-Alpine Lake Thun, Switzerland

Frontiers in Water, 2021
Pockmarks are crater-like depressions formed by upward fluid flow (gas and/or liquid) through the unconsolidated sediment column on the floor of oceans and lakes.

Millions of seafloor pits, not pockmarks, induced by vertebrates in the North Sea

Communications Earth & Environment, 2023
Seabed pockmarks are among the most prominent morphologic structures in the oceans. They are usually interpreted as surface manifestation of hydrocarbon fluids venting from sediments.
