Team George Irvine, Pina Porceddu, Nanci LeVake
Objective Check visibility, familiarize Pina to upstream/downstream junction.
Logistics George and Nanci: single stage (not using back gas) Pina: back gas
Bottom Time 40 minutes
Maximum Depth 143 FFW
Results The basin was fairly clear but green and 2 degrees F colder than the water in the cave. The visibility remained less than optimal to the upstream/downstream junction with a very green tint. We swam upstream and took the first left jump. Visibility was less green there. We familiarized Pina with the 20 foot and 70 foot and 120 foot bottle drops and the upstream/downstream junction.

Objective Continue exploring a lead previously worked by Deschamps and Lais. Secondary objective was to collect survey data of tannic tunnel at 1st tee downstream from Emerald.
Logistics Single scooter each with third scooter in tow. Double stage.
Bottom Time 70 min
Maximum Depth 148
Results Discovered tannic water just past first tee to the left. After further inspection, tannic water was observed to be syphoning into the left-side tunnel from the right (usually tannic) tunnel. Primary and secondary objective aborted. Just prior to the dive, John Rose stated that the sinks to the south were all tannic. It appears that the tannic water is moving north up through the system. Proceeded to meet OC team of McKinlay and Koritz at the Black Abyss and assist, however they had not returned from their dive at that time.

Objective Check condition of existing main line; repair and replace as necessary.
Logistics 1 stage, 1 scooter each.
Bottom Time 40
Maximum Depth 150
Results The basin silted out immediately requiring an on-the-line entry from the surface down to clear water at ~ 60 feet. The old main line was not visible so we ran new line to the upstream/downstream junction. We repaired and replaced the section of line downstream to where it makes a sharp left. We left the line tied off on the wall for the push team. All the old line is in very poor condition; broken and buried in many places and stained black. From 60 feet to the upstream/downstream junction there was a deep layer of tannic water. It cleared up some from there. There was a moderate siphon. We advised the support team to run new white line from the main line below the dumpster all the way up and over it then parallelling the thick permanent rope out to the surface so the remaining teams could have an easier exit in close to zero vis.

Objective Explore and survey downstream section.
Logistics Double stage, double scooters. Irvine and McKinlay using 42 amp primaries.
Bottom Time 90
Maximum Depth 160
Results Zero visibility to upstream/downstream junction @ 130ft depth. Decided to reline and resurvey entire passageway from entrance. Reached the end of the downstream line and continued exploration. Several large leads off the main passageway with depth averaging 150ft. Visibility averaged 50ft or so with blue tinge to the water. Lots of debris in the system and very silty.
