Great Meteor Seamount Circulation Revisited: Insights Into Cold‐Water Coral Habitat Potential

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Seamounts play a crucial role in shaping deep‐sea ecosystem structure, influencing ocean circulation, enhancing biological productivity, and supporting diverse marine life. The Great Meteor Seamount (GMS), is the largest seamount in the North Atlantic and a key ecological feature in the regional network of the Protected Areas of the Azores ...

Drone-based photogrammetry reveals differences in humpback whale body condition and mass across North Atlantic foraging grounds

open access: yesFrontiers in Marine Science
Baleen whales are key consumers in marine ecosystems and can serve as ecosystem sentinels. Body condition, defined as an individual’s energy stores relative to its structural size, can provide a useful proxy for health in baleen whales.

Predicting Historical Populations and Evaluating Shifting Baselines of Traditionally Exploited Fisheries

open access: yesFish and Fisheries, Volume 27, Issue 3, Page 506-518, May 2026.
ABSTRACT Development of data‐intensive stock assessment and ecosystem‐based models has improved our understanding of shifting species abundance in response to fishing, ocean ecology, and species interactions. Along with this analytical progress is evidence that many stocks lack data required for complex models, resulting in data‐limited options for ...

Automated Detection and Classification of Marine Species Vocalizations Using a YOLO‐Based Deep Learning Framework

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study proposes a YOLO‐inspired deep learning framework to automatically detect and classify marine species vocalizations, using a synthetic dataset to simulate realistic overlapping and non‐overlapping conditions. The model demonstrated strong performance and high precision, establishing a baseline for implementing real‐time passive acoustic ...

Tagging Very Small Fish: Two Effective and Low Impact Methods

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 3, Page 213-224, April 2026.
ABSTRACT Identifying individuals over time and across contexts is essential in many scientific fields. There are a variety of well‐established methods for uniquely marking individuals (e.g., visible implant elastomer, barcodes, paint). However, for some species, life history stages, and/or experiments, existing methods are not sufficient.

A. A. Berzin and His Memoir [PDF]

open access: yes, 2008
Alfred A. Berzin began to study whales in 1955 at the Pacific Research and Fisheries Center (TINRO) in Vladivostok where he is still working at the present time.

DNA extraction from formalin-fixed Franciscana tissues [PDF]

open access: yes, 2002
The present paper reports the extraction of DNA from formalin-fixed Pontoporia blainvillei tissues. Following the Vachot and Monerot (1996) protocol, fragmented DNA (300-700bp) was extracted from more than 95% of liver and muscle samples.

Breeding habitat of poorly studied humpback whales (Megaptera novaeangliae) in Boa Vista, Cape Verde [PDF]

open access: yes
The waters surrounding Cape Verde comprise one of two known breeding grounds for humpback whales in the North Atlantic. The population remains very small and has apparently failed to recover since the cessation of whaling there.
