Mission Day 1: Rebreather testing
Work began quickly:
Warren and Doug successfully installed the new software changes for the Inspiration rebreathers that will allow the vision electronics to function properly in saturation out of Aquarius. During our pre-dives it quickly became apparent that the new changes would work. After calibrating the units we swam around Aquarius for about 20 minutes focusing on the partial pressure of O2 on the displays. The 20 minute initial dive went well and showed promise for the upcoming dives.
After our first dive our confidence in the software change provided by Ambient Pressure Diving had grown and we prepped for a second afternoon dive. The units will be calibrated at depth tomorrow, but we dove the same partial pressures of O2 settings as the am dive. The dive was to 95 fsw for 120 minutes. The PPO2 range was from .70 to .90. I considered it a successful dive.
