Secret Quarry Bottomed
Sunday 9th August 2009
Trev and Dave of the "Castawaydivers" today bottomed the secret quarry with the help of Jim and Tat giving surface cover.
The temperature at the surface was 22 degrees and had dropped to 6 degrees by the time we had descended to around 8m. Any natural light from the surface had disappeared by the usual 10 to 12m leaving us with just torch light.
The dive plan was to take water samples at 30m, 38m and a sample of the black sludge at 39.6m that the bottom is lined with. Trev put the full length of his arm down into the black sludge but could not feel a solid bottom.
We have now got samples from the surface, 10m, 20m, 30m, 38m and the bottom at nearly 40m these will be be going of for analysis.
