Bering Sea


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.
