Epifauna counts from BOWLS moorings deployed and recovered from R/V Oceanus cruises OC1304A and OC1406B off the Coast of Oregon from 2013-2014 (BOWLS project)

Abstract:

This dataset contains counts of epifaunal organism Phyla from BOWLS moorings deployed in April of 2013 and recovered in June of 2014. Phyla sampled: Annelida, Arthropoda, Chaetognatha, Chordata, Cnidaria, Echinodermata, Kinorhynca, Mollusca, Nematoda, Nemertea, and Platyhelminthes. Also included are the mooring identifiers, substrate type (control, wood, whale-bone), latitude, longitude, depth, and deployment and recovery dates.

Methods & Sampling

Immediately upon recovery of the benthic landers (moorings), experimental substrates and associated mesh bags were transferred to buckets containing chilled, filtered seawater. Following the collection of ecosystem function measurements, epifaunal individuals were:

1) washed from the mesh bag over a 500 μm sieve, split and fixed in each 95% ethanol and 4% formaldehyde
2) picked from the surface of each substrate using forceps and fixed in each 95% ethanol and 4% formaldehyde
3) washed from the bucket over a 500 um sieve, split and fixed in each 95% ethanol and 4% formaldehyde following removal of the substrate.

Epifaunal samples, preserved in both 95% ethanol and 4% formaldehyde were quantitatively sorted in the lab using a stereomicroscope. The “substrate” is the experimental treatment type; Control, Whale-bone or Wood. Phylum counts are the number of individuals (or heads for incomplete specimens) per three replicate substrates at each mooring.

BCO-DMO Data Manager Processing notes:
* Added conventional header with dataset name, PI name, version date
* Column names reformatted to comply with BCO-DMO standards
* Combined individual files for cruise epifauna into one dataset
* Added mooring deployment location, dates and depths from BOWLS Moorings dataset (https://www.bco-dmo.org/dataset/568713)
