Regionalization of benthic hard-bottom communities across the Pourtalès Terrace, Florida
نویسندگان
چکیده
The Pourtalès Terrace is an exposed hard-bottom platform located south of the Florida Keys in 200–450 m depth with a diverse deep-sea coral ecosystem dominated by stylasterid hydrocorals, octocorals, and sponges that supports recreational commercial fisheries. Portions have been designated as managed areas absence detailed habitat maps, which hampers identifying ecological benefits derived from such management actions. Here we report analyses historic physiographic geologic data more recent high-resolution bathymetric benthic to statistically derive community characterization across Terrace. Multivariate faunal density 42 standardized sites showed spatially distinct communities: East Terrace, West Upper Edge, Sinkholes Lophelia Coral Mound (the southernmost record this continental U.S.). These corresponded divisions into comprised Central Karst-like regions, Lower A description these communities provided. This study presents new insights spatial arrangement necessary step towards facilitating mapping. Our recommendations highlight information needed for map creation collecting determine if current conservation boundaries match goals.

Benthic O2 exchange across hard-bottom substrates quantified by eddy correlation in a sub-Arctic fjord
Oxygen exchange across the seabed is a key measure for quantifying benthic carbon turnover. However, technical limitations have restricted such measurements to sedimentary areas. Few assessments on hard-bottom substrates exist although such biotopes are frequent along many coastlines. In spring 2009, we used the non-invasive eddy correlation technique to quantify the in situ O2 exchange rate ac...
