Summary

R/V SEWARD JOHNSON and JOHNSON-SEA-LINK SUBMERSIBLE
July 9 – August 9, 2010

This report finalizes the compilation and submission of field notes, site notes, and sample data
from the Florida Shelf-Edge Expedition (FLoSEE) that was conducted by Harbor Branch
Oceanographic Institute, Florida Atlantic University (HBOI-FAU) as part of the Year 2 science
plan for the Cooperative Institute for Ocean Exploration, Research, and Technology (CIOERT).
The expedition was originally scheduled for spring 2011, however, when the Deepwater Horizon
oil spill occurred, permission was requested and approved by NOAA/OAR/OER to conduct the
expedition in the summer of 2010 to assess the response of benthic and midwater organisms to
the oil spill along the west Florida shelf.

Areas of Operation:
The areas of operation focused on deepwater coral reefs and mesophotic reefs along the east,
south, and west Florida shelf and slope. This extends from central eastern Florida through the
Straits of Florida to the Tortugas,and eastern Gulf of Mexico along the west Florida shelf and
slope. In general, we targeted deepwater reefs, shelf-edge reefs (mesophotic reefs), and hardbottom
essential fish habitat. Selection of specific sites within this region depended in part upon
the progression of the oil plume, projected trajectories, and collaboration with NOAA, MMS,
USGS and other agencies. Using seafloor maps from previously collected acoustic surveys,
Johnson-Sea-Link submersible dives were planned to cover areas that had not been explored
during previous dives, as well as areas that had been visited during previous expeditions to
enable temporal comparisons.
