I’m new to diving, so I just wanted to get some input about my last dive. Everybody’s dive buddy, Greg said I should put this on a thread for everybody to see. I didn’t intend to go wreck diving, but I just had to check out a strange sight. My buddy and I were descending to our intended reef site, but I saw that the water looked more green than blue off towards the east side of the reef. I remembered a dive documentary once where Phillip Cousteau saw an unusual color in water from his helicopter and when they landed and investigated it turned out to be a ridiculously huge school of fish. I wondered if that may be the case in what I saw. There was nothing really going on at the reef it seemed relatively inactive and I decided to investigate the green water. As we swam further away from the reef to the east the green became even more pronounced and seemed to be coming from a single spot on the bottom ahead. As we got closer to the source my first thought was that there was a detailed model of a ship that somebody had put in a green bottle. As we continued to swim it became obvious that the ship was full size and much further away than I thought the vis would allow us to see. The ship was obviously not in a bottle, but surrounded by some kind of green glow. I’ve heard of phosphorescent algae and seen wisps of it, but never so much at once. I was really concerned that we were getting too far from our boat, so we turned back. Like I said, I’m not real familiar with actual wreck diving, but I’ve seen quite a few documentaries and such. Isn’t a shipwreck supposed to look...well wrecked? This ship looked so good, that, as I said, at first I thought it was a model. The ship looked like some kind of commercial vessel as it had what appeared to be football goalposts near the front just to the rear of a boxy looking bridge and a structure that looked like a really large radio broadcast tower laying on its side covering the span of the flat deck. Just behind the tower like structure were two smoke stacks side by side and several “J” shaped ducts behind them. Does anybody know what I may have been looking at?
