Researchers say their absence is a stark reminder that the orcas are slowly starving to death because there is not enough Chinook salmon to sustain them.

Fiji and other Pacific island nations are vulnerable to rising seas that have flooded villages and forced residents to abandon their homes.

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

Rising sea temperatures may mean prey swimming in deeper water out of reach of guillemots, razorbills, puffins and kittiwakes

A blob menacing Hawaii is now visible from space. A massive heatwave in the Pacific Ocean is killing off coral. Satellites are capturing the destruction so that scientists can learn how to rebuild the reefs.

Thousands of jellyfish clogged up a cooling system and threatened to suspend production at a power plant in Israel. Video filmed at the Electric Company power plant on Thursday shows the light blue sea creatures being swept down a chute and into a bin. The power plant, based in the coastal city of Ashkelon, about 15 miles north of the Gaza strip, uses seawater to cool its

Three great white sharks broke the border rules big-time on Friday. The sharks were tracking very tight to shore near South Shore communities.

Look down into the waters of the Venice canals today and there is a surprising sight – not just a clear view of the sandy bed, but shoals of tiny fish, scuttling crabs and multi-coloured plant-life.

A rare whale-dolphin hybrid species has been discovered off the coast of Hawaii, scientists say. The animal is the first-ever documented offspring of a rough-toothed dolphin and the rare melon-headed whale, a team from the Cascadia Research Collective concluded in a report released this week.

Robert Prescott, of the Wellfleet Bay Wildlife Sanctuary, believes a warming trend allowed the turtles to delay their migration south.

Russian scientists in the Arctic Ocean said they have discovered the most powerful methane gas fountain ever recorded, highlighting the danger of this greenhouse gas accelerating climate change or causing an oil or gas spill as it erupts from thawing permafrost.

One UBC scientist says his early estimation that a billion creatures died from the 2021 heat dome was too low. Today, life is returning to areas scorched by last year’s unprecedented heat wave. The die off was patchy and the plants and animals in the intertidal zone that survived the heat wave “are the parents to the next generation,” Harley said.

Declining fertility and rising mortality, exacerbated by fishing industry, prompts experts to warn whales could be extinct by 2040

Areas starved of oxygen in open ocean and by coasts have soared in recent decades, risking dire consequences for marine life and humanity

From Belize to Barbados, tourist beaches have been swamped by huge tides of foul-smelling sargassum – and climate change could make the problem worse

An incredibly rare octopus invasion may have been caused by recent storms. Storm Ophelia, quickly followed by Storm Brian caused huge waves and storm surges as gusts of up to 80 mph hit the Welsh coast.

‘Catastrophic breeding event’ leads to demands for a marine protected area to be set up in East Antarctica

Plastic waste in the ocean is now so widespread it is polluting remote ice floes in the Arctic, scientists have discovered.
