Dive R503
						Dive Plan: ASHES Vent Field - 1) Recover 2 high temp. recorders and 2 Vemco low temp recorders. 2) Deploy Osmosampler/HOBO package at Hell. 3) Recover 8-10 bacteria traps. 4) Suction sample bacterial mat at trap locations.
						Dive Configuration: Suction Sampler, BioBox with 4 microbial trap arrays & 2 high temperature HOBOs. NO still camera.
						Note: Nav fixes not edited in the logs. All fixes were logged, regardless of accuracy. Use the dive plots to determine actual positions.
