Trevor,

I believe marine fauna are fairly common near sea ice.  This implies
that flora are there also, at the base of the food chain.  Which I
always hear about the nutrient-rich arctic waters, where the nutrients
in questions are minerals for the flora.  So algae probably are
abundant in your harbor until it ices over.  I have no idea what ice
would do to the light intensity in the water underneath, but it might
knock it down enough to crash algal populations.  Now what it was that
was doing bioluminescence, I do not know.
