Yeuck! The sea was all green and sickly looking in places, today.
A kind of foamy gungy mess, clearly the result of an algal bloom I would think.
Algal blooms are, of course, natural processes and not all are toxic by any means. Looking at google images for algal bloom, this one is of miniscule proportions. Nevertheless it didn't look very nice. I blame the lovely warm spring weather, and relatively calm seas allowing the algae (presumably some sort of dinoflagellate) to reproduce madly.
