On 8 May 2010, a gray whale was sighted off the Israeli Mediterranean shore and twenty-two days later, the same individual was sighted in Spanish Mediterranean waters. Since gray whales were last recorded in the North Atlantic in the 1700s, these sightings prompted much speculation about this whale's population origin. Here, we consider three hypotheses for the origin of this individual: (1) it represents a vagrant individual from the larger extant population of gray whales found in the eastern…

New Holocene grey whale (Eschrichtius robustus) material from North Carolina: the most complete North Atlantic grey whale skeleton to date

Skeletal remains and historical accounts indicate that grey whales (Eschrichtius robustus) existed in the North Atlantic Ocean from the Pleistocene into the seventeenth century. Fossil and sub-fossil

Observation of the gray whale (Eschrichtius robustus) in the Laptev Sea

The gray whale (Eschrichtius robustus) as an Arctic species with seasonal migration may serve an indicator for climate changes in the Arctic (Moore and Huntington, 2008).

Forgotten Mediterranean calving grounds of grey and North Atlantic right whales: evidence from Roman archaeological records

The evidence that these two coastal and highly accessible species were present along the shores of the Roman Empire raises the hypothesis that they may have formed the basis of a forgotten whaling industry, and significantly extend the known range of the Atlantic grey whale.

The inference of gray whale (Eschrichtius robustus) historical population attributes from whole-genome sequences

The results indicate that gray whale genomes contain low nucleotide diversity and have been subject to both historical and recent inbreeding, which suggests that novel migratory routes may develop within the next century and if so this could help retain overall genetic diversity.

Omura's whale off West Africa: autochthonous population or inter-oceanic vagrant in the Atlantic Ocean?

Beach surveys remain a useful tool to assess trends in cetacean species composition, to detect unusual mortality events and to help assess the impacts of anthropogenic activities in remote areas where the marine mammal fauna is poorly known and where fisheries effort is high.

Critically endangered western gray whales migrate to the eastern North Pacific

Satellite-monitored tags attached to seven Western North Pacific gray whales indicate that the population identity of whales off Sakhalin Island needs further evaluation and provides evidence of navigational skills across open water that break the near-shore north–south migratory paradigm of EGWs.

Climate impacts on transocean dispersal and habitat in gray whales from the Pleistocene to 2100

These first genetic data for Atlantic gray whales suggest that two recent sightings of gray whales in the Atlantic may represent the beginning of the expansion of this species' habitat beyond its currently realized range.

A white humpback whale (Megaptera novaeangliae) in the Atlantic Ocean, Svalbard, Norway, August 2012

A white humpback whale was observed on several occasions off Svalbard, Norway, during August 2012; the rarity of observations of such white individuals suggests that they are born at very low frequencies or that the ontogenetic survival rates of the colour morph are low.



The western gray whale: a review of past exploitation, current status and potential threats

Gray whales (Eschrichtius robustus) occur along the eastern and western coastlines of the North Pacific as two geographically isolated populations and have traditionally been divided into the eastern

Gray Whale ( Eschrichtius robustus ) Sightings in Eastern Beaufort Sea

Gray whales ( Eschrichtius robustus , Lilljeborg) migrate north each spring to feeding grounds, mainly in the Bering and Chukchi Seas. Regularly a few individuals travel as far northeast as Point

Gray whale distribution relative to forage habitat in the northern Bering Sea: current conditions and retrospective summary

A retrospective summary of gray whale and benthic fauna distribution and abundance was undertaken and available measures of biomass suggest a downturn in amphipod productivity from 1983 to 2000, when estimates ofgray whale popu...

Gray whale Eschrichtius robustus population and stock identity

The available data strongly indicate that western gray whales represent a population geographically isolated from eastern gray whales and therefore that the western and eastern populations should be treated as separate management units.

It is clear that non-indigenous species are a significant force of change in marine and especially estuarine communities globally and studies of marine communities that do not include NIS are increasingly incomplete.

A quarter of a world away: female humpback whale moves 10 000 km between breeding areas

This report reports on a female humpback whale first identified by natural markings off Brazil that subsequently was photographed off Madagascar, whose minimum travel distance is greater than 9800 km, more than twice the species' typical seasonal migratory distance and the longest documented movement by a mammal.

Impacts of climate change on ice-related species categories are categorized for: ice-obligate species that rely on sea ice platforms, ice-associated species that are adapted to sea ice-dominated ecosystems, and seasonally migrant species for which sea ice can act as a barrier.
