Meiofauna higher taxa density (abundance per m2), and Nematode genera counts (100-150 individuals per slice) from multiple corer samples (0-5 cm sediment depth, Ocean Instruments MC800) taken during 2019 Research Vessel Point Sur expedition (#PS20-8) to the West Florida Slope and Escarpment, Eastern Gulf of Mexico. Conducted under the auspices of the NOAA funded (NA180AR0110285) project: Combining habitat suitability and physical oceanography for targeted discovery of new benthic communities on the west Florida slope (Hydrosmac). This dataset contains the original files submitted to the OBIS-USA IPT, the processed files that are published in the OBIS-USA IPT, and the scripts that were used in processing.

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...
