Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

Recent Sediment Analysis, Study Case: Sub Bottom Profiler Data Line 8 Geomarine Research Vessels

Journal of Wetlands Environmental Management, 2019
North Aru Island’s offshore had a long exploration history since 1973 until present. The characteristics of seabed can be studied through the shapes, acoustic reflection pattern, type of substrate or sediment, or by living organisms at the seafloor.

Finding the Best Nursery: How Habitat Features Shape Juvenile Snapper (Chrysophrys auratus) Density

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
This study examines habitat preferences of juvenile Australasian snapper (Chrysophrys auratus) in northeastern New Zealand, analysing data from 113 stations across structured and unstructured habitats. We investigated how juvenile snapper densities were influenced by environmental factors, including prey availability and physical habitat features ...

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.

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

Fish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.

Assessment of Bottom Trawl Impacts on the Status of Seabed Communities in European Seas

Fish and Fisheries, Volume 27, Issue 2, Page 285-299, March 2026.
ABSTRACT Bottom trawling affects seabed habitats, but its large‐scale impacts remain poorly quantified. Assessment of trawling impacts is essential to support monitoring and achieving sustainability objectives under international conventions, sustainable development goals, and seafood certification programs.

The influence of the geomorphological and sedimentological settings on the distribution of epibenthic assemblages on a flat topped hill on the over-deepened shelf of the western Weddell Sea (Southern Ocean) [PDF]

, 2014
Epibenthos communities play an important role in the marine ecosystems of the Weddell Sea. Information on the factors controlling their structure and distribution are, however, still rare. In particular, the interactions between environmental factors and
