Science Log

Our last day of ROV dives and it was definitely worthwhile. PISCES held off the coast of South Carolina at the Edisto MPA (Marine Protection Area). We were able to get in four dives with the ROV. The scientists paid close attention to the marine habitat within the ecosystems of all four dives. The interesting conclusion was that all four dives had very different habitats. What is even more interesting is that these differing habitats affect the number of animals that live there. Some of the areas we saw were smooth sandy bottom and interspersed on the smooth bottom are rugged rocky outcrops.

The rocky reefs range in height from some being really short to some being very tall. Some of the rocky reefs can even be in a small area the size of a dinner plate and others are hundreds of square miles.

The important fact of the matter is that the rugged hard bottom is favored by many species of animals including corals, sponges, and other invertebrates. Scientists find that sunken ships or other debris that ends up at the bottom of the ocean becomes perfect habitat for animals. These areas protect fish species during spawning and from predators. Today’s discovery is that the most fish species we have seen was found not in the smooth sandy bottom but in fact in the rugged rocky outcrops and rocky reef ranges.

Things I have seen today:

hammerhead shark
sea turtle
sea cucumber
spotted goat fish
lobster
pencil urchin
banded butterfly fish
sand tilefish
sea biscuit
