Proliferation of thick brown algae is affecting fishing, tourism and marine life on both sides of the Atlantic, say scientists
Three great white sharks broke the border rules big-time on Friday. The sharks were tracking very tight to shore near South Shore communities.
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.
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.
Fuel shipments normally take place during autumn from departure ports such as Murmansk and Arkhangelsk. However, last fall saw a sudden freeze-up and quickly accumulating sea-ice on the Northern Sea Route, including the Kara Sea. Of the two rescued barges, one contained 7,000 tons of diesel fuel, while the other was loaded with 170 tons of kerosene.
King and snow crab populations in the Bering Sea have plummeted ahead of the harvest season, some by 99% compared to previous years.
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.
Major sea lice epidemics have erupted on Atlantic salmon fish farms on Vancouver Island’s west coast over the last three months, according to industry, Fisheries and Oceans Canada and independent reports.
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.
Scientists examining the devastating impact plastics are having on the world's oceans have identified seabirds with more than 250 man made objects lodged in their stomachs.
From Belize to Barbados, tourist beaches have been swamped by huge tides of foul-smelling sargassum – and climate change could make the problem worse
Australia has seen an unprecedented number of widespread, catastrophic transformations in response to extreme weather events.
Research finds farmed salmon virus may cause jaundice/anemia.
High winds that pushed water high up on south facing shores of the Seward Peninsula cause shoreline erosion on the Chukchi Sea coast of Shishmaref, last week.
Graves at the historic St. Michael cemetery in Alaska are eroding due to increased storms and erosion, prompting an archaeologist to recover exposed remains and coordinate efforts to re-bury them. Tom Wolforth’s prime mission was to appropriately handle the remains and make sure they could be reburied. He has been working closely with the tribe and the municipality to address their concerns. One concern, Martin said, was that these exposed remains could pose a risk of disease, especially if the dead had been buried during the time of the 1918 flu pandemic. But Wolforth assured them that if properly handled this shouldn’t be a problem.
The Bering Sea’s cold pool, a critical part of the seafloor ecosystem, had shrunk to a worrying degree in recent years, but it is continuing to slowly return, according to the latest results of NOAA’s bottom trawl survey. Saffron cod, also called tomcod, seems to be bouncing back after a few bad years, and Arctic cod and blue king crab numbers were also better.
After alerting the region to very high levels of harmful algal blooms west of Kotzebue and Gambell two weeks ago, scientist onboard the research vessel Norseman II have found even higher numbers of Alexandrium catenella algae cells near Wales, Diomede and Shishmaref.
