NCCOS Assists Response to Multispecies Mortality Event in St. George Island, Alaska
A rapid, multi-agency response is underway on St. George Island, Alaska, to investigate a multispecies mortality event linked to a harmful algal bloom, with concerns that paralytic shellfish poison (PSP) toxins may be affecting local wildlife and human health.

Paralytic Shellfish Toxin Advisory

Red sea mystery off Hawke's Bay coast
The Hawke's Bay Regional Council is taking tests and awaiting results from a likely algal bloom spreading across the sea off the Hawke's Bay coast. Coastwatchers say the reddish-brown discolouration has been growing over several weeks – visitors to the Bluff Hill lookout reported what may have been its early signs on January 31, when it appeared to be coming from a ship apparently circling at sea off the Port of Napier.

Algae Observed in Satellite Image - Could This Be Related to Shearwater Die-offs?
This region in the Bering Sea began to change color in early July, during roughly the same period when dead shearwaters began being reported by LEO members in coastal communities. Ocean experts suspect it's a non-toxic coccolithophore bloom. Interestingly, these kinds of blooms have occurred before in conjunction with shearwater die-offs. But this may be circumstantial.

When Alaska shellfish turns deadly
No one really knows why algae put so much effort into making poisons. Alexandrium makes saxitoxin, and causes PSP. Another algae called Pseudo-nitzschia produces domoic acid, the source of amnesiac shellfish poisoning.
