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.

The number of ships entering Canada's Northwest Passage, and the distances sailed, are all increasing, says a new report from the Arctic Council.

Unusual waxy, white substance washed up on beach.

The concentration of the heat-trapping gas topped 420 parts per million, while the planet has warmed more than two degrees. This is the highest daily average concentration to be recorded. Data was collected at the Mauna Loa Observatory on the Big Island of Hawaii.

Parts of Northern Siberia were up to 7℃ warmer than normal in 2020. The warming is the most significant along parts of the North Siberian coast, and especially around the peninsulas of Taymyr and Yamal. This has been brought on, in part, by polar vortex on the Arctic coast.

Salmon sharks are rarely seen this far south; typically they swim off Alaska and in the northern Pacific Ocean where they have access to their favorite food.

A harp seal pup sits on a snow-covered beach near the town of Blanc-Sablon, Québec, in early March. Normally harp seals give birth and raise their pups on sea ice in the Gulf of St. Lawrence, but this year’s ice coverage is at an all-time low, throwing pups’ survival into jeopardy.

As sea ice off Alaska continues its long-term vanishing trend, two seal species that depend on ice may be showing the effects in their bodies. Ribbon seals, distinctive for their black-and-white striped patterns on their fur, and spotted seals, known for their speckled coats, became thinner over time.

Magne Vorland (27) was surprised when he saw what was coming to the surface. "Unusual," says the expert.

The sea temperatures around Iceland have been higher than the average for the past 20 years, and the sea around the whole country has become more acidic, according to data recorded by the Marine Research Institute.

Moss balls imported from Ukraine to pet shops in the United States have been found to house the invasive Zebra mussel. Once in bodies of water, this mussel reproduces rapidly and wreaks havoc on ecosystems.

Preliminary numbers say this was the largest cold-stunning event in recorded U.S. history.

A humpback whale spotted off Bremer Bay late last week is believed to be the earliest sighting ever of the species on WA’s south coast. Humpback whales are usually spotted of WA's south coast in late March or early April. The whale's early appearance has prompted concerns from scientists about the lack of food stocks in Antarctica.

Coastal seabirds have experienced significant die-offs in Western Alaska the past few years. But recent results suggest that offshore birds are also feeling the impact of low ice and warming ocean temperatures in the Bering Sea.

The Hawke's Bay Regional Council is taking tests and awaiting results from a likely algal bloom spreading across the sea off the Hawke's Bay coast. Coastwatchers say the reddish-brown discolouration has been growing over several weeks – visitors to the Bluff Hill lookout reported what may have been its early signs on January 31, when it appeared to be coming from a ship apparently circling at sea off the Port of Napier.

White, dust-like deposit on the beach on sunny day after high tides. Water samples would be required for identification.
