A global assessment of abyssal–hadal vermiform lebensspuren: Functional consistency with depth

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Lebensspuren—sedimentary traces produced by benthic organisms—are widespread on deep‐sea floors but remain infrequently reported from abyssal (~ 3000–6000) and hadal (> 6000 m) environments. Here, we present the most comprehensive assessment of abyssal–hadal vermiform lebensspuren to date, spanning multiple ocean basins and reaching full‐ocean

Application of Seabed Remediation Technology to Pile Placement on the Jack-Up in Chengdao Oilfield

Haiyang Kaifa yu guanli
In order to reduce the risk of the moving platform being in place in the area of repeated pile insertion and extraction in Chengdao Oilfield, the uneven seabed formed by repeated pile insertion and extraction is repaired through seabed topography and ...

A review of subsurface geosystems and de-risking offshore construction in the Danish North Sea

GEUS Bulletin
The renewable energy transition has increased the demand for offshore construction in the Danish North Sea energy sector. This development underpins the need for further investigation of potential geological hazards and associated risks to avoid ...

Semi-Automated Mapping of Pockmarks from MBES Data Using Geomorphometry and Machine Learning-Driven Optimization

Remote Sensing
Accurate mapping of seafloor morphological features, such as pockmarks, is essential for marine spatial planning, geological hazard assessment, and environmental monitoring. Traditional manual delineation methods are often subjective and inefficient when

Seabed Morphology and Sedimentary Regimes defining Fishing Grounds along the Eastern Brazilian Shelf

Geosciences, 2018
Shelf morphology and sedimentary regimes are influenced by processes operating at different temporal and spatial scales and are important records of sea level changes and sediment supply and/or carbonate production.

Geomorphological classification in Bay of Biscay. Morpho-sedimentary mapping of the seabed in selected areas

, 2013
Les coraux d’eau froide, contrairement aux coraux tropicaux, n’ont pas besoin de lumière et peuvent se développer en profondeur. Les espèces constructrices comme Lophelia pertusa et Madrepora occulata ont une distribution mondiale et sont présentes de la Norvège à la Grèce sous forme de monts carbonatés ou de récifs.

Modeling and forecast of gas hydrate distribution in the Black Sea: main principles and approaches

Frontiers in Earth Science
Gas hydrates are prevalent in marine sediments in regions characterized by certain bathymetry, geomorphology, lithology, and physics (i.e., low temperature and high pressure conditions).

A Study of Geomorphological Features of the Seabed and the Relationship to Deep-Sea Communities on the Western Slope of Hatton Bank (NE Atlantic Ocean)

, 2012
This chapter provides the connection between the seabed morphology and the invertebrate benthic species communities along the western upper-middle slope of Hatton Bank between 600 and 2,000 m water depth, an important area for deep-sea fisheries. Two major seabed domains can be distinguished: outcrop, described as a nondepositional area corresponding ...

Ocean-bottom seismometers document how submarine landslides develop and grow

Communications Earth & Environment
Submarine landslides reshape seafloor geomorphology, transport sediment and carbon to the deep-sea, and can trigger tsunamis or damage valuable seabed infrastructure. Yet, submarine landslides have never been directly observed in action. Here, we present
