I am an Advanced Open Water Diver. I plan to do three dives. The first dive is a 25-metre/80-foot dive for 22 minutes followed by a 52-minute surface interval. The second dive is to 20 metres/70 feet for 27 minutes followed by a surface interval of 62 minutes. My third dive is to 18 metres/60 feet. What would be my maximum allowable bottom time for this third dive?
34 minutes

I dive to 17 metres/56 feet for 47 minutes. After a 30-minute surface interval I do a second dive to 17 metres/56 feet. Losing track of time, I notice my bottom time is now 25 minutes. According to the General Rules, what should I do?
