Function and diversity of the Ship, Trinity, and Tiger Shoal Complex, with emphasis on macrofauna and spawning blue crabs (Callinectes sapidus) ArchiMer
Gelpi, Carey.
The ecological and economic value of sandy shoals off the Louisiana coast is not well understood. During three years of comprehensive benthic sampling and environmental measurements I studied the Ship, Trinity, Tiger Shoal Complex (STTSC), which comprises changing and discrete benthic habitats including high relief sandy shoals, and muddier, mostly deeper off-shoal areas, prone to hypoxia. Benthic macrofaunal assemblages of shoals included endemic species, and shoal communities were significantly different from each other and the muddier offshoal habitat, contributing to northern Gulf of Mexico (GoM) regional biodiversity. Sand percentage was the most influential environmental parameter shaping macrofaunal community composition across the region. My study...

Diversity and composition of macrobenthic community associated with sandy shoals of the Louisiana continental shelf ArchiMer
Dubois, Stanislas; Gelpi, Carey; Condrey, Richard E.; Grippo, Mark A.; Fleeger, John W..
Along the Louisiana, USA continental shelf, sandy shoals are shallow, possibly oxygen-rich "islands" surrounded by deeper muddy deposits prone to hypoxia. Shoals also contain significant quantities of fine sand that may be mined in the future for coastal restoration. The ecological role of shoals remains poorly understood and we hypothesized that shoals provide critical habitat for benthic invertebrates. Using Ship Shoal as a model system, we assessed the diversity and structure of macrobenthic assemblages and how community structure varies with season and environmental parameters. High biomass (averaging 26.7 g m(-2)) and high diversity (161 species) of macrobenthos was found in 2006. Polychaetes (45%-72 species) and crustaceans comprised most of the...
