Hello! This is C Watch! Today we mustered on the quarterdeck in the morning to discuss guidelines for snorkeling, as well as reef studies that we would contribute to. We separated into three groups: Group 1 counted parrot fish, which are indicative of coral health; Group 2 counted echinoderms, mollusks, worms and lobsters to research biodiversity; and Group 3 counted recruit versus adult corals. Prior to snorkeling, the squall that was pouring on us subsided and gave way to a stunning double rainbow. Some students then departed to explore the reefs while conducting our assigned surveys.
We saw a plethora of fishes, including foureye butterfly fishes, stoplight parrotfish, reef squirrelfish and glassy sweepers schooling in a nearby cave. We also spotted sea lettuce, a banded coral shrimp, a common octopus, as well as very intriguing non-photosynthetic corals near the entrance of the cave.
At the conclusion of snorkeling, we again mustered on the quarterdeck to compile our findings. According to the organism counts, the reef exhibited reasonably good coral health and high vertebrate/invertebrate diversity and abundance. Snorkeling was undeniably one of the many highlights of our trip, and we are looking forward to the rest of our adventure!
