Upstream EN to the end of the line was 50-60 feet of viz with a few spots dropping and a few spots better.
At the end of the line, looking into the cave with the daisy chain in front of you, the lower right (deeper section) was tannic starting at 252 and was 5 feet of viz.
Lots of poking and prodding around and 4hrs 45 minutes later we surface.
Viz in the basin was pretty good at about 50 feet...ish.

What part of a cave is a basin?
Thanks for the report.
Smartass comment or genuine confusion?Quote:

Haha, no, I mean it, it think I missed the part of the class that explained it or have simply forgot.Quote:

Some people would call it the "head pool". It is the open water above the cave entrance. At Eagles Nest, there is a really big head pool/basin.Quote:

Might. Might not. Meh.

Forrests' explanation is spot on, I only included it for the Nest as it can be bad. Pretty darn bad. And it makes it less enjoyable.Quote:

Also, some people have pretty detailed spread sheets created to try and predict when EN will have the best viz and what the head pool (basin) conditions are is usually included.
Bob
These spread sheets are posted somewhere?
We were there on thursday as well around 10-1ish.
It was my first time and very nice dive.

That is very interesting indeed. That room down to the right at the end of the upstream gold line often has clearer colder water in it. My thought has always been that it is just a room with still water in it. Was the tannic water noticeably colder?Quote:

and def no cyber stalking here... maybe more like the cyber stalked.... :)

I didnt check the temp on the computer but I'd guess 5 degrees colder. James can confirm my thoughts, though. As an aside: the small lead had a nice bit of flow coming out of it. Made our attempted move through disappear quickly.Quote:

(Never mind)
Could be a late season turnover, much the way a lake does. Usually, after it's done it clears up nicely.
Caves in Florida, or sections of caves in Florida, that are connected to lakes and ponds turn over (as Sly-vester mentioned). Because of minimal water movement, the primary means of water movement is density variations. In the summer, hot surface waters make the lakes less dense than the underlying cave waters and no lake water enters the cave. In the winter, cooling increases the density of the surface water and flows into the cave along bottom topography - cave water ascends along the roof the cave to the basins to replace descending surface water. Seasonal turnover happens at a number of locations, including low-flow caves in the Mill Pond, Eagle's Nest and Rose Creek Sink (just to name a few examples).
I don't know if the situation fits in this case, but when a user's screen name contains a diacritical mark not normally used in English, there's a good chance English is not his/her native tongue. Just sayin'.Quote:

Hey, who's the grammar cop here?
I trust your have serviced your power inflator? Didnt seem to function properly when we first arrived at the Daisy chain.Quote:

Between diving and complaining about not getting to dive certain caves, James has no time to service useless dive gear like inflator valves.
Wow. Perfect.Quote:

Your assertion about the name is correct, it's portuguese, means peacock. I'm originally from Brazil.Quote:

Early? We ran 15 minutes longer than our expected runtime and 15 minutes less than the outside.
My God, man!
HOWEVER, I fail to see the correlation.
I will take chance number 3 at Indian on Friday, please.
For some friggin reason.
Bob
Which is why, in my opinion, Eagle's Nest more often has better visibility in the summer than in the winter - tannic surface water is warmer than the cave water so doesn't seep down into the cave as much. In the winter the dirty surface water is colder and denser than the cave water so it sinks into the cave, so the visibility is frequently poor in the winter.Quote:

As a side note, where the tannic was wasnt the deepest portion of our dive. Must have been relative to surface water location and water movement within the cave.?.
Bob
That is exactly correct. You can predict the approximate time of turning based on when daily temperatures begin dropping substantially below cave temperature. Incidentally, we see the same density driven exchange in air-filled caves in Florida. Many become density stratified in summer and CO2 concentrations build to dangerous levels due to the lack of flushing with fresh outside air.Quote:
