Journal of Maps, 2023 We present the bathy-morphological map at a scale of 1: 50,000 of the area around the submerged Ferdinandea Island, the ‘Neverland’ of the Sicily Channel (central Mediterranean Sea).

Geohimicheskaja harakteristika donnyh otlozhenij v zone pokmarkov v vostochnoj chasti Finskogo zaliva [The geochemical characteristics of the bottom sediment in the pockmark area of the eastern part of the Gulf of Finland] [PDF]
Балтийский регион, 2011 It is the first time pockmark-like structures have been detected in the south-eastern part of the Gulf of Finland with the help of a side-scan sonar and a profile recorder.

Seismic Anisotropy Within an Active Fluid Flow Structure: Scanner Pockmark, North Sea
Frontiers in Earth Science, 2021 Understanding sub-seabed fluid flow mechanisms is important for determining their significance for ocean chemistry and to define fluid pathways above sub-seafloor CO2 storage reservoirs.

Fracture-controlled fluid transport supports microbial methane-oxidizing communities at Vestnesa Ridge [PDF]
Biogeosciences, 2019 We report a rare observation of a mini-fracture in near-surface sediments (30 cm below the seafloor) visualized using a rotational scanning X-ray of a core recovered from the Lomvi pockmark, Vestnesa Ridge, west of Svalbard (1200 m water ...

Frontiers in Marine Science, 2021 Cold seeps occur globally in areas where gases escape from the seafloor, occasionally resulting in the formation of topographic depressions (pockmarks), characterised by unique physicochemical conditions such as anoxic and sulphuric sediments.

Structures in Shallow Marine Sediments Associated with Gas and Fluid Migration
Journal of Marine Science and Engineering, 2021 Geological structure changes, including deformations and ruptures, developed in shallow marine sediments are well recognized but were not systematically reviewed in previous studies. These structures, generally developed at a depth less than 1000 m below

Pockmarks: Refuges for marine benthic biodiversity [PDF]
Limnology and Oceanography, 2009 Pockmarks are one of the most obvious and abundant structural features of the North Sea seabed, yet their influence on fauna is virtually unknown. We report the distribution of benthic megafaunal assemblages in and around four "pockmark complexes" in the North Sea to determine the structure of megafaunal communities inside pockmarks and whether these ...

Origin of High Density Seabed Pockmark Fields and Their Use in Inferring Bottom Currents
Geosciences, 2018 Some of the highest density pockmark fields in the world have been observed on the northwest Australian continental shelf (>700/km2) where they occur in muddy, organic-rich sediment around carbonate banks and paleochannels.

Geophysical evidence for submarine methane seepage on the Western slope of Okinawa Trough
Frontiers in Earth Science, 2022 Identifying seafloor methane seepage efficiently has important implications for assessing environmental impact, reducing the uncertainty of top seal integrity, understanding the petroleum system, and mitigating the drilling hazards due to shallow gas ...

Molluscs from a shallow-water whale-fall and their affinities with adjacent benthic communities on the Swedish west coast [PDF]
, 2013 We conducted a species-level study of molluscs associated with a 5-m long carcass of a minke whale at a depth of 125 m in the Kosterfjord (North Sea, Sweden).
