Effects of heavy metal contamination on burial rates of Austrovenus stutchburyi: Implications for sediment transport [PDF]

, 2009
Urbanisation in coastal catchments has significantly increased not only the input of terrestrial sediment to the marine environment but also the input of contaminants.

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 ...

Infragravity Waves Across a Steep‐Sloping Rough Rocky Seabed on the Inner Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Observations of infragravity (IG) waves were conducted from June to October 2023 along the rocky shores off China Rock, CA, on the inner shelf at depths of 8–13 m. The study examines inner‐shelf IG wave dynamics over rough, steep rocky shores and compares them with those over smoother, gentler sandy shores and coral reefs. IG energy correlated

Classification of Seabed Types by OBIA With Recursive Feature Elimination Corrected by Expert Interpretation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The characteristics of seabed types are of great importance for understanding the marine environment and the changes taking place there, spatial planning, seabed investments, and natural resources extraction.

Characterizing the Distribution of Nepheloid Layers and Their Response to Hydrodynamics in the NE Rockall Trough, NE Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Suspended and slow‐sinking particles, especially those concentrated within nepheloid layers, can act as pivotal mediators of oceanic carbon transport and benthic‐pelagic coupling. However, identifying nepheloid layers and distinguishing their composition (i.e., inorganic particles, phytoplankton, zooplankton, and fish) using only acoustic ...

Semi-Supervised Learning for Sediment Classification Using Convolutional Neural Networks with Digital Elevation Model and Backscatter Data

Archives of Acoustics
Accurate sediment classification is crucial for advancing marine research, environmental monitoring, and sustainable seabed use. However, acquiring large amounts of labeled data in such settings is often challenging, expensive, and time-consuming.

Brine Pool Microbes Enrich Metalliferous Sediments in Salt Giant Basins

AGU Advances, Volume 7, Issue 6, September 2026.
Abstract We report the discovery of an extinct deep‐sea brine pool in the Red Sea's Hume Deep, providing evidence that rift‐shoulder pools are ephemeral on millennial timescales, and that the microbially‐enriched metalliferous deposits produced during the pool's active phase persist into the stratigraphic record.

Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.
