I'm in decompression status here. I'm now at (only) 35 feet, having already been at some depth and come back up. The dive is 34 minutes long now, and as usual I expect to go at least 60 minutes on this dive. I have 1388 psi of air left of the 2800 I started with. I have to take (at least) 12 minutes to ascend now, with a ceiling of 10 feet. Then I'll have a 3-minute safety stop. So if I want to come up right now, I have at least 15 minutes of time to spend lower than 10 feet. I need to conserve air and hope for a nice shallow end of the dive to burn off those 12 minutes.
