Using Distributed Temperature Sensing for Long-Term Monitoring of Pockmark Activity in the Gulf of Patras (Greece): Data Processing Hints and Preliminary Findings [PDF]
Sensors, 2023 Patras Gulf pockmark field (Western Greece) is a tectonically controlled field that has been activated at least twice by strong earthquakes (M5.4, 14 July 1993 and M6.4, 8 June 2008), and episodic gas seepages have been recorded in the past using ...

An extensive pockmark field on the upper Atlantic margin of Southeast Brazil: spatial analysis and its relationship with salt diapirism [PDF]
Heliyon, 2017 We present new evidence for the existence of a large pockmark field on the continental slope of the Santos Basin, offshore southeast Brazil. A recent high-resolution multibeam bathymetric survey revealed 984 pockmarks across a smooth seabed at water ...

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

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).

Linking geology and microbiology: inactive pockmarks affect sediment microbial community structure. [PDF]
PLoS ONE, 2014 Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive.

Low-Frequency Sound Propagation in an Underwater Waveguide with a Giant Gassy Pockmark
Journal of Marine Science and Engineering, 2023 Bottom formations known as pockmarks basically arise due to extensive gas emission. Active pockmarks are characterized by exceptionally high gas saturation and substantially reduced sound speed.

Geology and Mineral Resources of World Ocean, 2019 The article considers the existing models of pokmark formation, processes and structures that form them. Special attention is paid to the regularities of their development in the Black Sea, shape, size and features that are of interest for further study due to their potential search feature on hydrocarbons.
