Moon jelly blooms

Multiple blooms of thousands of small clear/white moon jellies, close to surface of water and layered much deeper. 4-6 large patches of jellies over the course of 30 minute boat ride through the channel returning from the bay. Each bloom has many hundreds or maybe thousands at once, some in smaller/thinner groups of maybe 100 or fewer. Pockets found across the full channel from the mouth of the inlet to the furthest inland point (Little Bay). Breathtakingly beautiful.
