Title: Macrobenthic community structure and total sediment respiration at cold hydrocarbon seeps in the northern Gulf of Mexico
Author: Nunnally, Clifton Charles
Abstract: Cold seeps are areas of high biomass in the deep -sea , the impacts of these food -rich environments upon the sediment community is unknown in the Gulf of Mexico . The structure and function of benthic communities was investigated at food -rich and food -limited sites on the northern Gulf of Mexico continental slope . Cold seeps were richer in macrofauna densities and total sediment respiration , but were poorer in biomass and taxa diversity than normal slope communities . Decreased diversity is seen at most chemosynthetic communities and suggests a competition for resources . The spatial extent of these results at seeps is unknown and may be a localized , bioenhancement effect caused by seeping fluids .
