Dive Haven

Diving conditions were 20' vis 75 degrees at 15' but as soon as you dropped below 15' it went to 3'-5' vis and 53 degrees.

I think it might be a thermocline! Found this post above ours!

I have trouble believing that it was really 69 degrees at 20 feet for your first dive, it is likely that the temperature sensor wasn't given enough exposure at that depth to register the actual temperature. Noting your shallower 2nd dive it shows a seemingly more accurate 57 degrees. Either way that is still cold, about exactly the same as Lanier. I logged 44 degrees at 76 feet in Lanier recently.

The temps in the quarry very drastically depending on location. It actually dropped one degrees per foot until 30' according to the computer on descent and vice versa on ascent!

Dive one between 20-30' the temps is 69-59^o range at the beginning of the dives! I was at 30' in 3 minutes! Dive Two, The descent was rather fast with me at 30' in 1 minute! Second Dive, on descend was 69-60^o! Then in the middle of the dives 20' is 53-57^o(different places in the quarry)!

So the safety stops vary 60-68^o from the time you start your stop until time to end the stop. Lag time does seem to occur on ascent, which would let you assume it occurs on descent(which seems to be at a similar rate)!

I am thinking the temps very by location and the thermocline plays a big part in the drastic temperature change around 30'! Also the location of the spring could be a factor! Another thing might be shadowing in the quarry, it might keep areas cooler because of less sun exposure.

What was the vis. like this weekend? Is the vis. still bad?
