Today we completed our PADI Deep Dive. The dive was to a depth of 90 ft. Before the dive we learnt about nitrogen narcosis, which affects a diver at deeper depths, slowing reaction times. On land we did a small reaction time test and then repeated it at depth. The results were clear that some shipmates were showing the first signs of nitrogen narcosis. Another amazing aspect of the dive was the effect that depth had on color, as red light doesn’t travel that deep making everything seem bluish in color. All in all it was one of the best dives so far.
