6 Today the Seward Johnson II moved up the coastline
from Ft. Pierce, Florida towards Savannah Scarp, approximately
70 miles off the coast of Savannah, Georgia. Here scientists
will begin researching fish and reef habitats, conduct habitat
characterizations, and collect deep water soft corals for
DNA analysis. During this leg of the mission, the R/V Palmetto
from the South Carolina Department of Natural Resources will
support scientists aboard the Seward Johnson II, conducting
various fish studies. Discover what scientists expect to discover
at Savannah Scarp. |

September
7 There were two submersible dives today. Scientists
are researching the fish and reef habitats of this area, and
have had success so far with clear weather, and numerous observations
of reef and fish habitats. Tonight we plan to conduct net
tows to collect additional data on the fish species that utilize
this unique habitat. Learn more about the features of Savannah
Scarp. |

8 With the first day of submersible diving
at a close, scientists have already made many observations
about the oceanographic characteristics and fish habitats
at the Savannah Scarp. Read observations of Chief Scientist
George Sedberry on fish abundance and diversity after a submersible
dive at a section of the Savannah Scarp colorfully named Sandwich
Reef. |

9 Savannah Scarp is comprised of a variety of rocky
"substrates," or geological characteristics of the
seafloor. Hard substrates, like rocks, provide stable environments
for organisms that prefer to be immobile. Soft substrates,
or sediment plains, host fewer fish populations. Learn about
the geology of this unique area, view some of the samples
collected for analysis, and read an interview with Venetia
Butler, the expedition's teacher-at-sea. |

10 Although Savannah Scarp and Gray's Reef National
Marine Sanctuary are near each other along the Georgia coast,
the areas are visibly different, even on the surface. Scientists
were anxious to explore further differences in these environments
using a submersible. Read about their discoveries, the observations
of graduate student Jill Jennings and Paulette Powers, chief
scientist aboard the mission support vessel R/V Palmetto,
and watch a short video clip of one of the seas' most interesting
creatures, the octopus. |
