These data represent several benthic cores collected near chemosynthetic seep habitats during 2009 and 2012. Sediment cores were collected near several natural hydrocarbon seeps with ROV deployed push cores. The purpose of these samples is to examine benthic communities associated with natural hydrocarbon seepage in the deep sea as well as compare these communities to areas associated with the Deepwater Horizon oil blowout. Samples were collected in the northern Gulf of Mexico, mostly south of Louisiana, and at depths ranging from 500 to 2600 meters. Sample processing and species identification occurred from 2014 – 2016. Macrofauna (>300 um) were identified to the lowest taxonomic unit.

Submarine canyons are morphologically complex systems, acting as major conduits of organic matter along continental shelves, promoting gradients in food resources, habitat heterogeneity, and areas of sediment resuspension and deposition. Often environmental conditions within canyons can be highly distinct, particularly in different parts of the canyon and in contrast to adjacent slopes. Here we examine how biogeochemical drivers shape the differences between canyon and slope infaunal communities in Baltimore and Norfolk Canyons in the U.S. Mid-Atlantic Region. Specific comparisons included macrofaunal communities in Norfolk canyons and adjacent slope, hard substrate associated macrofaunal communities in Norfolk...
