Areas within the South Atlantic Bight that will be explored during the Islands in the Stream 2002 expedition..


Exploring Underwater Oases

July 27 - September 1, 2002

"Islands in the Stream 2002: Exploring Underwater Oases" consisted of four scientific investigations to study the continental shelf break and slope from the eastern coast of Florida to North Carolina — an area known as the South Atlantic Bight. The mission took place in three "legs" and focused on the characterization of deep-reef habitats, with particular emphasis on the discovery, exploration and description of reef fish spawning sites; exploration of the unique outer shelf and slope habitats off the Carolinas; discovery of new resources with pharmaceutical potential; and exploration of vision and bioluminescence in the deep-sea benthos.

Each project was conducted by groups of interdisciplinary investigators led by scientists from the South Carolina Department of Natural Resources, North Carolina National Estuarine Research Reserve, and the Harbor Branch Oceanographic Institution (HBOI). They used the R/V Seward Johnson and the Johnson-Sea-Link submersible for direct access to this rarely seen underwater world.

Background information for this exploration can be found on the left side of the page. Daily updates are included below. Detailed logs and summaries of exploration activities are found on the right.
