- A chunky 15-20 feet, 20+ feet in the shallows (outgoing tide)
jellies! small to medium fried egg jellies, sea gooseberries, comb jelly, water jelly, cross jelly, aggregating jelly,
starry flounder, sand star, leather star, giant pink star, sand dollars, aeolid type nudibranch, lewis moon snail, eel grass, saragassum, giant plumose anemone, tube anemone, feather worms,
The dive was all about the jellies for me- sweet spot is 15-30' and dive with a light current to have the jellies going by.
Dive report for 3/20/25
- Visibility
- 5 feet, 10 feet in the shallows (outgoing tide)
in the shallows, the water was chunky with algae and about 10' visibility down to about 25'. Then, the algae cleared out mostly and the water got silty, but stayed at a 10-15' visibility down till about 85' or so. From 85'-106' (our max depth), the water was more muddy and reduced visibility to 5' or less.
Creatures: pink Tritonia, Dendronotus iris (a few with the white coloring and one with the red/rainbow coloring), graceful crab, Blackeyed hermit crab, sand star, leather star
Jellies were primarily in the water column from the surface to 50'. When I say small- think ½ inch or so for these little guys bodies: thimble jelly, tailed jelly, sea gooseberry, then the larger ones: water jelly, cross jelly, and aggregating jelly.
I didn't pay attention to the water temp, but it felt near the 46F range... I dind't feel a thermocline in the water column.
