Decadal‐Scale Bathymetric Change in a Shallow Coastal Bay

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Coastal marshes and bays must accumulate sediment to maintain their position relative to mean sea level during periods of sea level rise (SLR). Resuspension of bay‐bottom sediment, which together with tidal inundation promotes marsh deposition, is sensitive to water depth, but quantitative measurements of bathymetric change across shallow bays

First Direct Observations of Dilute Antarctic Turbidity Currents Associated With Dense Water Overflows

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Turbidity currents are increasingly recognised as a key mechanism for transporting sediment into the deep ocean, yet their structure, behavior, and long‐term impact in Antarctic submarine canyons remain poorly understood owing to a lack of direct observations.

Deep blueprint: A literature review and guide to automated image classification for ecologists

Journal of Animal Ecology, Volume 95, Issue 9, Page 1558-1585, September 2026.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Ocean sediments and shifting baselines—A call to revise European habitat classifications

Journal of Applied Ecology, Volume 63, Issue 9, September 2026.
Shifting baselines affect the appropriateness of existing habitat classification frameworks, potentially reducing MPA integrity and efficacy. To enable representative mapping, accurate sensitivity assessments and appropriate management of marine habitats, EUNIS classifications require more flexibility.

Prokaryotic Novelty and Metabolic Diversity in the Tagoro Shallow Hydrothermal System (Canary Islands, Spain)

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrothermal activity at the Tagoro submarine volcano shapes distinct epipelagic and benthic prokaryotic communities. Microbial diversity decreases towards vent sources, yet novel taxa dominate and potentially contribute to iron, nitrogen, sulphur and methane cycling in this shallow hydrothermal system with high unexplored microbial diversity ...

Large-Scale Seabed Sediment Classification Using Sentinel-2 Imagery and Efficient Machine Learning Pipelines

IEEE Access
Large-scale mapping of seabed sediments is essential for environmental management, offshore engineering, and the sustainable exploitation of resources, particularly in optically complex coastal regions such as the Brazilian Equatorial Margin (BEM ...

Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance

Global Policy, Volume 17, Issue 4, Page 764-772, September 2026.
ABSTRACT This article examines how low‐certainty scientific claims permeate high‐stakes policy debates before rigorous validation. Using deep‐sea mining governance as a focal domain, the study traces high‐visibility narratives, including the “dark oxygen” hypothesis, radioactive risks of polymetallic nodules, projected impacts of sediment plume ...

Learning From Crushing Failures: Changes in Physical Properties Reveal the Mechanics of Submarine Carbonate Landslides

Basin Research, Volume 38, Issue 5, September‐October 2026.
Changes in the physical properties of calcareous ooze between intact weak layers and glide planes within the same stratigraphy provide new constraints on the deformation processes and mechanical factors that control the mobility and erosive behaviour of submarine carbonate landslides.

Unprecedented Warming and Increased Herbivory Drive Collapse of Japan's Kelp Forests

Global Change Biology, Volume 32, Issue 9, September 2026.
Rapid warming during the Kuroshio Large Meander intensified marine heatwaves beyond kelp physiological limits while simultaneously extending grazing windows of thermally expanding herbivorous fishes. This synergistic interaction between climate‐driven thermal stress and prolonged herbivory triggered kelp forest collapse and a persistent shift to barren

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface
