9:18 Before box-dredging, a SeaViewer drop camera is typically lowered in the water to scan and film the topography of the bottom; this ensures that fragile biotic communities will not be harmed by the dredge.
The video clip documents the bottom in... the Northeastern Gulf of Mexico in the vicinity of the Florida Middleground, FLorida, at depths of 45-95 m. Special emphasis is placed on collecting marine macroalgae (seaweeds), macrocrustaceans, and molluscs.
The seaweeds highlighted in this clip include representatives of green (Codium) and brown macroalgae (Sargassum).
This dredging expedition on board the R/V Pelican (LUMCON) took place May 28-June 10, 2006.
This expedition was sponsored by National Science Foundation Biodiversity Surveys and Inventories grant DEB-0315995 (Suzanne Fredericq & Darryl Felder, PIs, University of Louisiana at Lafayette).
