Today was another early morning, setting sail from Anegada to Marina Cay after a relaxing recovery day at Loblolly Bay. I was Skipper of the Day with Quinton as my navigator. We had a remotely easy three hour beam reach sail to Marina Cay.

After some amazing Couscous salad, we had a plankton lesson and decided to undertake a little plankton experiment. Since plankton undergo a diel migration every night, we decided to do two tows to see the difference between day and night. Using our plankton tow net, we went on a 15 minute tow, once at 4:30pm and once at 9:15pm. The water samples are cooling to slow the movement of zooplankton so we can identify the plankton and zooplankton tonight with our microscope.

In the afternoon, we went for a snorkel to check out Diamond Reef, located off Great Camanoe, at a 2 minute boat ride from Scrub Island. We hopped back in the water around 7:00pm to see the crepuscular transition and stayed for about an hour to see the beginning of the night creatures coming out to feed. We watched as a big hawksbill turtle found a nice nook to sleep in for the night. We also found an octopus trying to eat a fish and some huge basket stars on the end of gorgonians with its arms spread to filter all the plankton that went by. It was an extraordinary night snorkel!
