Bird flu has been detected in two ringed seals near Resolute Bay, Nunavut, following a previous case in a seabird, marking an unusual occurrence of the virus in marine mammals.

Tyuleniy Island, also known as the ‘Island of the Seals,’ is located in the Sea of Okhotsk and is an important breeding ground for northern fur seals (Callorhinus ursinus). More than 300 northern fur seals and Steller sea lions have been found dead in a mystery mass die-off on a small, uninhabited island in Siberia.

A new study has found evidence connecting the rapid warming of the region with a physical decline in three species of Alaska seals.

Russian authorities are investigating the mysterious death of nearly 300 endangered seals that had been discovered washed up on the shores of the Caspian Sea. 272 dead Caspian seals have been found at a number of locations in the southern region of Dagestan.

The event caused a die off of up to 95% of marine life along the seabed. The Russia's Academy of Sciences announced that the mass death was due to the effects of toxins from single-cell algae. Environmentalists are conducting their own inquiries and were not yet able to confirm the official probe's findings.

Environmental campaigners said they were conducting their own inquiries and were not yet able to confirm the official probe's findings.

The federal agency tasked to manage ice seals this week declared an Unusual Mortality Event, UME for short, for bearded, ringed and spotted seals in the Bering and Chukchi seas.

Since June 1 2018, NOAA has received reports of 282 dead ice seals in the Bering and Chukchi seas. NOAA said they typically receive reports of about 29 ice seal strandings a year.

NOAA is investigating what it’s calling “unusually large numbers” of seal deaths.

Officials are warning residents in Roddickton, Newfoundland to keep their distance from seals that have wandered into town. According to resident Brendon Fitzpatrick, some have crawled 6 to 8 km away from the ocean.

Deaths of gray and harbor seals, in much greater numbers than usual, have been attributed to viruses related to distemper and the flu.

Many of the dead seals that washed ashore in northern New England in the past few weeks tested positive for either avian influenza or phocine distemper virus, but it is still too soon to say if those viruses are the primary causes of the unusual die-off.

Preliminary results suggest that avian flu and/or phocine distemper virus may be contributing to the elevated seal strandings in Maine, New Hampshire, and Massachusetts since June 1, 2018.

130 dead seals washed up in Russia's Lake Baikal, and scientists have taken lake water samples and biopsies of the animals. Preliminary theories about the die-off did not suggest pollution is the reason.

Pacific walruses are beaching on Northwest Alaska shores, peppered with bleeding skin legions that have been observed on dying ringed seals in Arctic Alaska, according to federal biologists.

A mysterious disease, possibly a virus, has afflicted ring seals along Alaska's coast, killing scores of them since July, local and federal agencies said on Thursday.

Scientists say they've been unable to solve the mystery of dead seals that washed ashore in Labrador between December and January.

Coxiella burnetii, a zoonotic bacterium, has recently been identified in several marine mammal species on the Pacific Coast of North America, but little is known about the epidemiology, transmission, and pathogenesis in these species.
