Jelly smacks — as these groups of jellies are unofficially called — are seasonal, but their emergence is predictable to an extent. Finding them consistently, in terms of place and time of year, is challenging — from year to year, conditions change: Currents shift, temperatures fluctuate, and biology does what biology does. But the crew of Nautilus Swell, the only live-aboard consistently trekking southeast Alaska, seems to have solved this problem with a dive site they call Smudges. On the northeastern side of Baranoff Island, there is a narrow canyon that they bring divers to during the summer months to have an otherworldly jelly experience. The numbers of moon jellies there are massive, among other species of jellies.
