For years, researchers thought an infectious pathogen was behind sea star wasting disease. A new study found that multiple species of bacteria deplete oxygen from the water effectively suffocating sea stars. These microbes thrive when there are high levels of organic matter in warm water and create the low oxygen conditions.

Scientists scramble to explain unusual bloom of Sargassum
Recent research has found that coccolithophore blooms are occupying increasingly more space in the Barents Sea. Between 1998 and 2016, coccolithophore summer blooms have expanded poleward and their surface area in the Barents Sea has doubled.
Large holes had developed by mid-August in the low-concentration ice in the Chukchi and Beaufort seas, according to National Snow and Ice Data Center.
Karen Dunmall, a biologist with Fisheries and Oceans Canada, said pink salmon normally prefer warmer waters than the Arctic has been able to provide. But with the Arctic warming at up to three times the rate of the rest of the world, its waters are becoming more approachable for newcomers like this species.
Another attempt to pull free a luxury cruise ship with 206 people that ran aground in the world’s northernmost national park has failed after trying to use the high tide.
Up to 10 sperm whales have been stranded between Withernsea and Tunstall on the coast. Members of the coastguard and British Divers Marine Life Rescue (BDMLR) are on the beach, between Tunstall and Withernsea, near Hull.
While the population increased, the assessment did find that narwhals are sensitive to sound from boats and move away from boat traffic, Mike Hammill, the co-chair of COSEWIC’s marine mammals subcommittee, told Nunatsiaq News. Previously the species was listed as being of “special concern.”
“Our shipping monitors clocked another cruise ship going at excessive speed near Pond Inlet,” posted Baffinland Iron Mines on their Twitter account Sept. 22. While the maximum speed was agreed at nine knots in some passages used by the cruise ships, one ship in particular, The Hanseatic from Hapag-Lloyd Cruises, was clocked at almost 16 knots, nearly twice the velocity. It’s the second time this month the cruise line has been clocked in excess of the speed limit agreement.
It lost more than 40 per cent of its area in just two days at the end of July, researchers said on Thursday.
A red tide bloom was found in multiple areas of coastal Collier County. Individuals with chronic respiratory problems should be cautious and stay away from this location, as red tide can affect breathing. Residents near the beaches are encouraged to close windows and run the air conditioners.
A winter storm combined with a 20.7-foot high tide hammered the north shore of Kachemak Bay last Thursday.
Another Metro Vancouver beach has been closed to swimmers following concerns about bacteria.
The warm periods are linked with storms that penetrate into the Arctic from the Atlantic and Pacific oceans, and bring the temperature up by as much as 30 C in the middle of winter.
Herschel Island has seen a lot of people come and go. The Inuvialuit have used the place, known as Qikiqtaruk in Inuvialuktun, for at least 1,000 years.
It went through thin ice near the Tasmania Islands, in Franklin Strait, while the group was retracing its route back to Cambridge Bay,
