A sobering sight at 600 meters

On the very first Johnson Sea Link dive during this cruise, the very second thing seen on the bottom was the bottle shown in the video below shot by Johnson Sea Link crew.  This was observed at 600m (technically, it was at 1,850ft), in soft calcareous mud, over 45 nautical miles from land and 60 miles from the nearest town.  On the next dive, the scientists observed a lot of old longline fishing gear wrapped around the reef structure.  It seems, even in this remote location, which has never before been visited by humans, trash from human activities elsewhere has made its mark on the habitat.  It is a prominent and disturbing reminder of our impact on even the unseen parts of the planet.  I can only hope that this bottle becomes a home for some small thing, or that it becomes crusted over with coralline algae such that one day it is simply a bottle-shaped rhodolith
