There is a unexplained trend with sea otter carcasses on the beaches in Katmai National Park and Preserve. Many of the dead animals appeared to be in their prime.
The Bering Sea region, the Pacific gateway to the Arctic Ocean, is home to ecosystems on land and in the ocean that are both abundant and fragile. It’s also changing very quickly — and those changes offer a preview of the changes in store for other parts of the Arctic.
A decade-long warming trend in the Gulf of St. Lawrence continued in 2020. Water temperatures at depths of 200, 250 and 300 metres were higher than any measured in the Gulf since records started in 1915, hitting highs of 5.7 C, 6.6 C and 6.8 C. All were well above the normal variations.
Sitting in the Port of Dutch Harbor, the Polar Star is nearly 400 feet long and can break ice up to 21 feet thick. On Tuesday, the ship arrived for a pit stop with 136 crew members, 30 days into a months-long deployment to the Arctic. Their goal is to assert maritime sovereignty and security in the far north.
Cold temperatures and traffic congestion at the Panama Canal has resulted in a shortage of natural gas and exploding prices in parts of Asia. Now, Novatek aims to send LNG from the Arctic to Japan during the middle of winter in an untested high-risk, high-reward strategy.
It will become clearer in the coming days how the sunken barge owned by Laxa aquaculture in Reyðarfjörður, East Iceland, will be re-floated after this weekend’s storm. Divers are working on the vessel again today and, so far, it appears no diesel or other oil has leaked into the sea.
Bocaccio rockfish have made a huge comeback in B.C. since being deemed endangered in 2013, but the success story is being met with some trepidation as trawler fishermen can’t seem to avoid netting them now.
A closeup view of a bottlenose dolphin shows signs of skin lesions associated with a deadly skin disease known as ulcerative dermatitis. The increasing frequency and severity of storm systems drastically decrease the salinity of coastal waters, causing fatal skin disease in dolphins worldwide.
As winters get warmer, the number of drowning deaths is going up. "I just don't think we have appreciated that is one of the costs," said one scientist.
The appeal was sent to president Putin on 30 October on behalf of Moscow and St Petersburg surfing federations, pointing his attention to the fact that traces of rocket fuel were found in samples from the polluted area. It means that the anthropogenic version of the recent environmental catastrophe mustn’t be brushed aside, the surfers say.
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.
Now believed to be caused by an unprecedented algae bloom, the decimation of bottom-dwelling sea life may have devastating ripple effects.
A broad area of yellow foam is prompting some marine biologists to blame the catastrophe on a harmful algae. However, Governor Vladimir Solodov believes the most likely explanation is a spill. Tests have shown petroleum levels four times higher and phenol levels 2.5 times above normal.
Injured surfers and large number of dead sea creatures reported in Kamchatka region. Some experts have suggested highly toxic rocket fuel could have leaked into the sea. The first test site, Radygino, is about six miles (10km) from the sea.
Eugene Asicksik, the mayor at the time, had watched Shaktoolik’s shoreline erode for years. After the September 2013 storm threw tree-sized driftwood dangerously close to the homes, Eugene knew something had to be done to protect the community. He turned to beavers for inspiration, designing Shaktoolik’s first storm surge berm based on the impressive beaver dams upriver.
Researchers have identified an invasive blood-sucking parasite on mud shrimp in the waters of British Columbia's Calvert Island. The discovery represents the northern-most record of the parasite on the West Coast and is likely an indication of its ability to spread without human transport.
The expedition's easy journey from Greenland to the North Pole is another indicator of how the Arctic is impacted by climate change more than anywhere else on Earth, writes CBC's northern meteorologist.
The shrinking of chinook, sockeye, coho and chum salmon has a negative impact on the number of eggs fish lay, but smaller body sizes also mean fewer meals, fewer commercial fishing dollars and fewer nutrients transported into rivers every year.
The size of salmon returning to rivers in Alaska has declined dramatically over the past 60 years because they are spending fewer years at sea, according to a new study led by researchers at the University of California, Santa Cruz, and the University of Alaska Fairbanks.
At the outset, it seemed that there might be an environmental silver lining to the global pandemic. However, the same cannot be said for our oceans, which have been hard hit in recent months. COVID-19 triggered an estimated global use of 129 billion face masks and 65 billion gloves every month. If we stitched together all of the masks manufactured already, and projected to be produced, we’d be able to cover the entire landmass of Switzerland.
