Extreme Low Tide - updated
The tops of purple sea fans (Gorgonia ventalina) were exposed to the air for hours yesterday during flat calm sea conditions and an extremely low spring tide. The beacon at Eastern Blue Cut is in the background.
While dramatic, the surprisingly low low tide was a normal spring event. Tide predictions for Sunday show a very low tide was expected [see link]. Regardless, the tops of soft corals out on the reef, as well as seagrass meadows across Bermuda (see below), were exposed for hours to bright sunlight and little wind. This will probably result in some mortality and subtle ecological effects that will take some months to restore to normal.
