Visibility: 30+ feet, 10 feet in the shallows (incoming tide)

Visibility is meh in the shallows as there is a significant fresh water layer at the surface creating a nice halotherm as you descend. After you get through the top 10' it opens up nicely to 30' or so down to about 100' after 100' it drops to about 10' and then by 140'. it drops to about 3' of visibility. Water temp was about 49F today without any noticeable thermoclines. The dive was a sunflower star survey focused around 30-50' range with 8 sunflower stars surveyed with no signs of sea star wasting disease today!

Visibility: A silty 20 feet, 10-15 feet in the shallows (incoming tide)

Temp at 150’ was 49F, surface was high 50s. Visibility was variable throughout the water column: shallows down to 20’ were 10-15’, then 20+ feet vis down to 100’ or so, then started getting muddy as we got deeper with visibility in the 5’ range at 150’. Low oxygen event is appairant. There were a few larger sunflower stars in the 30-40’ range but we didn’t see any healthy , living sea whips.
