The N.W.T.'s Department of Environment and Climate Change and the Canadian Coast Guard tested samples from various locations in the area. The results showed no toxins present.

New Hampshire officials issued two warnings of potentially dangerous algae blooms along parts of Lake Winnipesaukee, the state’s largest lake. The New Hampshire Department of Environmental Services said on Thursday it detected high...

An unusually large Noctiluca bloom in Kasaan Bay. Noctiluca scintillans is a non-toxic algae bloom, generally considered harmless to humans.

High concentrations of harmful algae called Alexandrium catenella have been detected in the Bering Strait waters near St. Lawrence Island, Wales, and Little Diomede, posing a potential danger to human health and urging caution when consuming certain seafood.

A blue-green algae bloom in Yellowknife Bay sparked worry for people's dogs. Here's what an aquatic quality scientist and a veterinarian have to say about it.

Blue mussels collected on 6/15/2023, were way above the FDA limit for safe consumption of 80 μg/100g.

High levels of PSP toxins have been found in razor clams in Chignik Lagoon and blue mussels in Sand Point, Alaska, making them unsafe to eat and potentially causing paralytic shellfish poisoning, with no known cure.

Over the last several weeks the algae bloom has ranged from significant covering the surface of the lake in many places to today seeing patches of the bloom here and there on the surface. It can also be observed below the surface near the shoreline.

Testing has revealed black algae washing on Waiheke shores is toxic. “Currently the algal bloom on some Waiheke beaches could lead to skin or eye irritation if you are in contact with the water,” said Dr David Sinclair, Te Whatu Ora’s Northern Region medical officer of health.

There are miles of dead fish washing up on the beach. That's not all. Just breathing the air can be harmful.

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.

Test results show the bloom was almost certainly to blame for mass deaths of kina as well as crayfish, starfish and sea cucumber which washed ashore at Hardinge Rd, including Sandy Beach, and on a small part of Westshore Beach eight days ago.

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.

State scientists are testing the water for a toxic blue-green algae bloom at Twin Brook after tests showed 2 dogs had algae-related toxicity after swimming there Aug. 21.

Local officials and scientists have yet to nail down how many fish have died, but the reports have been coming in non-stop since Friday.

Researchers stepping off the research vessel Norseman II in Nome last weekend, brought significant news of having found very high concentrations of a phytoplankton called Alexandrium catenella in regional waters. Alexandrium is an algae that can produce saxitoxins, which can cause dangerous paralytic shellfish poisoning in people. The scientists issued an advisory, notifying Norton Sound Health Corporation, UAF Sea Grant and the Alaska Division of Public Health.

The algae on North Pond began blooming about two weeks ago during a patch of hot weather, making the pond resemble a bowl of pea soup, according to Danielle Wain, lake science director for 7 Lakes Alliance, which works to preserve land and water in the Belgrade Lakes region.

Scientists now say that the harmful alga will survive the winter and that it will probably turn green in the Oslo fjord next year as well.

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.
