Biological characterization of a mid‐water salinity maximum intrusion over the Northeast US Shelf
Limnology and Oceanography, Volume 71, Issue 5, May 2026.Abstract Salinity maximum intrusions, subsurface layers of anomalously salty and warm continental slope water moving onto the continental shelf along the thermocline, are recurring features over the Northeast US Shelf and represent an important cross‐shelf exchange mechanism.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning
Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Capelin Size, Condition, and Abundance Through Multiple Heatwaves in Alaska
Fisheries Oceanography, Volume 35, Issue 3, Page 413-429, May 2026.ABSTRACT Capelin (Mallotus spp.) are pelagic forage fishes that can be especially abundant in sub‐arctic marine ecosystems and are important prey for upper trophic‐level consumers. Abundance and distribution of capelin have been linked to ocean temperature, but the magnitude and directionality of thermal sensitivity can vary regionally.

Molecular Ecology, Volume 35, Issue 10, May 2026.ABSTRACT Effective population size (Ne), census size (Nc) and their ratio (Ne/Nc) are widely used indicators in conservation genetics, yet long‐term empirical data tracking of all three metrics over long time scales in wild populations remains rare. Using monitoring data from 1995 to 2020, we examined temporal dynamics of Ne, Nc and their relationship ...

Lanternfish (Myctophidae) from eastern Brazil, southwest Atlantic Ocean
Latin American Journal of Aquatic Research, 2014 Twenty-nine species from 11 genera of Myctophidae were taken in daytime midwater and bottom trawl hauls off eastern Brazil (11º-22ºS). Trawls were performed aboard the French R/V Thalassa to depths from 19 to 2271 m, including samples from shelf, slope ...

Dynamical analysis of the net and the otter-boards in a midwater trawl system.
NIPPON SUISAN GAKKAISHI, 1991 In order to obtain more knowledge about the control of a midwater trawl system, three electronic instruments were produced by way of traial to measure the motions of both the otter-boards and net under trawling operations with a full-scale net. These devices were used on the sampling trawl experiment.

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.Abstract The Deepwater Horizon (DWH) oil spill in the NE Gulf of Mexico in 2010 was the largest accidental spill globally. During and after the spill, oil was incorporated into marine snow (marine‐oil‐snow or MOS) and sedimented to the seafloor, accounting for ∼21% of the oil released.

A Computer Simulation for the Net Position Control of Midwater Trawl System.
NIPPON SUISAN GAKKAISHI, 2001 中層トロール漁法では, 常に目標魚群に対して網位置を迅速に制御しなければならない。本論文では, 著者らが提案した中層トロールシステムの運動特性を求めるモデルに基づいて, 東京水産大学の練習船神鷹丸に装備されている中層トロール網を例とした網位置の制御シミュレーションを行った。ワープ長または船速を制御入力とした網位置の動態は海上実験で捉えた現象をよく再現した。シミュレーションの結果を実操業に応用する例として, あるワープ長と船速における網位置から, ワープ長と船速を調整することで, 探知された目標魚群の位置へ網をより迅速に制御する方法を示した。また, 探索曳網中の初期ワープ長による制御出力(水深および制御時間)への影響が小さいことも確かめられた ...

Fisheries Oceanography, Volume 35, Issue 2, Page 285-296, March 2026.ABSTRACT Quantifying where marine organisms are born and subsequently disperse to is essential for fisheries management. Here, we conducted Lagrangian particle tracking of viviparous rockfish (Sebastes spp.) collected in the Southern California Bight over the course of 16 years.
