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.
Benthic macroinvertebrates from four habitat types (river channel, ephemeral side channel, river backwater, and seasonally inundated wetland) were examined from the Green River at the Ouray National Wildlife Refuge, Uintah County, UT, June-August 1991. For major taxa (Nematoda, Oligochaeta, Diptera: Ceratopogonidea, and Chironomidae) were quantified. Chuster analysis of densities showed that habitat types with comparable flow conditions were the most similar. Highest to lowest overall benthic invertebrate densities of the four habitats were as follows: ephemeral side channel, river backwater, seasonally inundated wetland, and river channel. Nematodes were the most abundant taxon in all habitat types and sample dates...
