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.

Papers in Palaeontology, Volume 12, Issue 5, September/October 2026.Abstract Dinosaur fossils from the Isle of Skye (Scotland, UK), particularly the abundant trace fossil record, provide a window into dinosaur evolution during the poorly known Middle Jurassic. Here we present a comprehensive description of the Duntulm tracksite from Cairidh Ghlumaig Bay, using aerial photography to provide whole site maps, catalogue ...

Poly-phased fluid flow in the giant fossil pockmark of Beauvoisin, SE basin of France
BSGF - Earth Sciences Bulletin, 2020 The giant Jurassic-aged pockmark field of Beauvoisin developed in a 800 m wide depression for over 3.4 Ma during the Oxfordian; it formed below about 600 m water depth.

Robust Underwater Image Classification Using Image Segmentation, CNN, and Dynamic ROI Approximation
Engineering Proceedings, 2022 Finding classified rectangular regions of interest (ROIs) in underwater images is still a challenge, and more so if the images pose low quality with respect to illumination conditions, sharpness, and noise.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management
Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Fluid Pathways and Sources Driving Recurring Pockmark Formation on the Chatham Rise, New Zealand
Basin Research, Volume 38, Issue 5, September‐October 2026.Quasi‐3D seismic data interpretation and spatial pattern analysis indicate that pockmark formation on the SW Chatham Rise is likely driven by a combination of compaction‐related dewatering during polygonal faulting and silica diagenesis, coupled with deeply‐sourced, possibly CO2‐rich fluids from subducted limestones migrating along prominent basement ...

Geobiology, Volume 24, Issue 5, September/October 2026.ABSTRACT The enigmatic Ediacara biota represents Earth's earliest example of macroscopic, complex life, yet the driving forces promoting their mid‐Ediacaran evolution and subsequent extinction across the Ediacaran–Cambrian boundary remain speculative. If these were true animals requiring oxygen for aerobic respiration, their rise has often been linked ...
