| Title: | Zooplankton abundance from ring net tows from RVIB Nathaniel B. Palmer NBP1801 in the Ross Sea, January 2018 (NCEI Accession 0278068) |
| Abstract: | This dataset contains biological, physical, and survey - biological data collected on RVIB Nathaniel B. Palmer during cruise NBP1801 in the South Pacific Ocean and Southern Ocean from 2018-01-10 to 2019-01-31. These data include abundance, depth, and sea surface temperature. The instruments used to collect these data include Isaacs-Kidd Midwater Trawl, Microscope-Optical, and Ring Net. These data were collected by Dr Grace Saba of Rutgers University as part of the "Using Bio-acoustics on an Autonomous Surveying Platform for the Examination of Phytoplankton-zooplankton and Fish Interactions in the Western Ross Sea (bio-acoustic plankton surveys)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-02-13. The following is the text of the dataset description provided by BCO-DMO: 2018 Ross Sea Zooplankton Abundance: ring net Dataset Description: Net tows were conducted during the R/V Nathaniel B. Palmer cruise NBP18-01 in Jan-Feb 2018. These data represent the zooplankton species and abundance analysis resulting from these sample collections. A companion dataset of mid-water trawls abundances is also available. |

| Supplementary information: | Acquisition Description: Sample collection : Net tows and mid-water trawls were conducted in the western Ross Sea, Antarctica on board the R/V Nathaniel B. Palmer in January-February 2018 (cruise number 18-01). Both the ring net (1 m diameter, 333 um mesh, non-filtering cod end) and the Issacs-Kidd Midwater Trawl (IKMT, 1.8 m frame, 500 um mesh, non-filtering cod end) were fitted with a calibrated General Oceanics flow meter. Contents of each tow were concentrated and preserved with buffered formaldehyde (4% final concentration) in 500 ml wide-mouth glass jars. Samples were sent back to the home laboratory (Rutgers University) for analysis. Analyses : Contents of each tow (or a subsample if the density of zooplankton or fish was high) were sorted by taxa and, in some cases, developmental stage. Measurements for abundance were conducted using a dissecting microscope (Zeiss Discovery.V8). Volume of water (cubic meter) that passed through the net/trawl during each tow was calculated using flowmeter rotor constant, flowmeter start and end values, and the area of net opening. Abundance per cubic meter per tow/trawl was then calculated for each species and, in some cases, developmental stage, by dividing the number of individuals for each species/developmental stage by the volume of water. |
