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.
