On July 14, a rare 100-pound opah fish was found on the Oregon coast. The 3.5 foot 100 pound fish washed up at Sunset Beach, and was reported to the Seaside Aquarium.

"The first wave of dead mussels washed ashore on July 14th, possibly earlier but this was the first report we received. I took the pictures included in my LEO observation on July 16th, and the temperatures were only just then beginning to climb into the upper 70s and lower 80s."

Caulerpa brachypus, which can spread rapidly and create dense mats, was found in July in Blind Bay and Tryphena Harbour. This was the first time the pest species had been detected in New Zealand.

Researchers on an expedition 300 kilometers west of Vancouver Island stumbled upon a group of 25-30 endangered sei whales.

In Malahat Drive in BC, an extraordinary heat wave, combined with low tides during the middle of the day resulted in the die off of possibly billions of intertidal invertebrates along the coast of British Columbia and Washington State.

Kwigillingok, a community on the Bering Sea coast of the Yukon-Kuskokwim Delta, is used to some flooding during high tides. But in recent years, that flooding has grown more severe, reaching a new threshold last week.

A record-shattering heat wave June 26-28 coincided with some of the year's lowest tides on Puget Sound. The combination was lethal for millions of mussels, clams, oysters, sand dollars, barnacles, sea stars, moon snails, and other tideland creatures exposed to three afternoons of intense heat.

Officials are still examining the substance in a lab to determine what it is, but DEC suspects it’s black tar or asphalt.

Westfall thanked his training with the Alaska Marine Safety Education Association to help him maximize his odds for survival.

The black substance was staining the feet of people at the beach, prompting one local resident to alert state officials.

However, if ingested by oysters and other shellfish, the sudden burst of a ciliate form of zooplankton — or animal plankton — called Mesodinium rubrum could turn their meat pink.

Increasing blanket of mucus-like substance in water threatens coral and fishing industry

The 60 ft blue whale carcass drifted ashore near Walvis Bay, Namibia on Tuesday. Local authorities were alerted and are planning to move the body, which had several injuries.

Scientists have confirmed the existence of a DDT dump site in the waters off the coast of Southern California, and it’s even bigger than they had anticipated.

“The big finding was that we really have something that’s coming out from a deep pool,” said Steinbach. As the permafrost thaws, it opens up new pathways that allow methane to pass through.

Scientists predict the world’s largest inland sea will shrink by a quarter due to climate change by the end of the century. In Derbent, waves that once threatened to engulf entire streets have retreated by around 100 meters, leaving miles of fresh sand dunes up and down the former shoreline.

Thousands of euphausiid shrimp, the species identified here in Resurrection Bay as Thysanoessa spinifera. were washed into the intertidal zone and on the beach near Whittier

The carcass of a 41-foot adult female gray whale landed at San Francisco’s Crissy Field on March 31. A second adult female was found April 3 at Moss Beach in San Mateo County. A third was found April 7 floating near the Berkeley Marina and the following day another at Muir Beach. A video of the fifth dead whale was posted on social media Friday.

Researchers in Canada find that population did not bother making the 6,000km roundtrip in 2018-2019

Odd Sørensen discovered this dead whooper swan on 10 April. The Norwegian Food Safety Authority has received daily reports of dead birds and are asking the public to help report bird mortality in particular with ducks, geese, swans, seagulls, eagles, buzzards, crowd and ravens.
