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).Sampling Description
Study Extent
Sediment samples were taken during the RV Point Sur expedition to the West Florida Slope and Escarpment, Eastern Gulf of Mexico (PS20-8, U. Southern Mississippi/LUMCON; IMO WSC2276) October 1-18, 2019.Sampling
Samples were taken using an Ocean Instruments MC800 multicorer and ROV push cores (USGS loan, operated by ROV Global Explorer). Sixty samples were completely processed for meiofauna higher taxa and nematode genus identification using morphological taxonomy, following standard scientific meiofauna protocols (32 – 500 micrometer) and the latest taxonomic literature. Samples contained 0-5 surface sediment from all relevant stations (1473-2267 m water depth range). A total of 20,927 individuals were identified to higher meiofauna taxon level (50% of the total yield was subsampled). Of these, 5,128 nematodes were identified to genus level. Twenty-two meiofauna groups were recognized. A total of 129 nematode genera were identified. Buffered formalin (10 % = 4% formaldehyde) sediment samples were used to extract the meiofauna using standard procedures (Heip et al., 1985; 32–500 μm sieves, LUDOX HS as centrifugation medium) to separate the organisms from the sediment particles. Fifty percent of all meiofauna were counted and between 100 and 150 nematode individuals were picked out randomly from each sample, transferred to anhydrous glycerol (Seinhorst, 1959) and mounted on slides. Meiofauna specimen preservation method: Buffered formalin (10%), stained with Rose Bengal Nematode Specimen preservation method: Buffered formalin (10%), stained with Rose Bengal, and mounted on glass slides with anhydrous glycerolQuality Control
All meiofauna were identified under a stereoscopic microscope (50x magnification), and nematodes were identified under a compound microscope (1000× magnification) to genus level using Platt and Warwick (1988), the latest taxonomic literature, and the NeMys nematode database and identification keys (nemys.ugent.be; linked to World Register of Marine Species). Specimens that could not be identified to the genus level were assigned to the appropriate higher taxon level.Method steps
