Researchers have logged the first satellite-telemetry record of common minke whale movements off the eastern coast of the United States, along with the first dive record for the species anywhere in the broader northwest Atlantic, bioengineer.org reports.

The team deployed three tags: two on whales in the New York Bight in September 2023 and one on a whale off Virginia in February 2024.

Because minke whales are cryptic and often occur in small groups, even this small sample offers an initial quantitative picture of a species long under-studied in these waters.

The tracking data revealed two distinct movement types: area restricted search (ARS) and transit, which the researchers interpret as foraging and migratory behavior respectively.

According to bioengineer.org, the New York Bight whales showed area restricted search in mid-shelf waters — including within offshore wind lease areas — supporting earlier suggestions the region serves as foraging grounds despite natural and human stressors there.

Most strikingly, one whale shifted from ARS to sustained transitory movement in late October, evidence the researchers describe as the onset of southward autumn migration.

Diving behavior differed sharply between the tagged animals. bioengineer.org notes that one tagged whale showed a clear day-night (diel) diving pattern, while the individual tagged off Virginia showed no such pattern at all.

The tags themselves mark a technical milestone: the three deployments yielded the species' first movement record in the area and its first dive record in the broader northwest Atlantic.

As a case report on just three whales, published 15 October 2026 with a permanent DOI, the authors frame the data as initial quantification rather than a comprehensive assessment.

The authors say the data provide insight for further research, management and conservation — relevant because the whales foraged inside offshore wind lease areas, where shipping lanes and development overlap habitat.

For comparison, BBC Wildlife Magazine's DiscoverWildlife reports a separate University of Auckland-led study tracking 21 southern right whales from New Zealand's Auckland Islands found half took a direct 42-day route to feeding grounds south of Australia while the rest took an L-shaped 64-day detour, both timed to peak prey availability.

Together, these telemetry studies show how tag data reveal whale behavior and habitat use that had previously gone undocumented.
