Seabed Classification Through Multifractal Analysis of Sidescan Sonar Imagery

, 1996
This paper presents a technique for the classification and analysis of seabed sediments from sidescan sonar image, the origins of which lie in the body of fractal theory.

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

Spatial Variability in Phytoplankton Response to Projected Increases in Iron and Temperature in the Ross Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract The Ross Sea supports massive phytoplankton blooms and exhibits the highest marine primary productivity rates due to seasonal relief of iron and light limitations. Although Earth System Models project regional increases in temperature and iron supply, there is uncertainty regarding the response of different phytoplankton communities. To assess

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 ...

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, Volume 95, Issue 9, Page 1762-1777, September 2026.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.

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.

Seabed classification by multibeam echo sounder

, 2016
Monikeilain on akustinen mittalaite, joka tuottaa korkearesoluutioista ja pistetiheydeltään peittävää pisteaineistoa merenpohjasta. Jokaiselle havainnolle saadaan sekä horisontaalinen että vertikaalinen sijainti.
