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.

Since bottom water temperatures have been warming drastically across the Northern Bering and Chukchi Seas over the last few years, cysts are now growing locally in Arctic waters. The blooms carry toxins, but scientists aren’t yet sure what impact they will have on marine mammals.

During a workshop in Nome this week, scientists and residents discussed algal toxins’ role in the changing Bering Sea ecosystem.
