Zooplankton abundance and stages from MOCNESS nets from the RVIB Nathaniel B. Palmer from the Southern Ocean, 2001-2002 (SOGLOBEC project, Southern Ocean Krill project) (NCEI Accession 0112171)
This dataset contains biological and survey - biological data collected on RVIB Nathaniel B. Palmer during cruises NBP0103, NBP0104, NBP0202, and NBP0204 in the South Atlantic Ocean, South Pacific Ocean, and Southern Ocean from 2001-04-29 to 2002-09-11. These data include depth_close, depth_open, stage, and taxon. The instruments used to collect these data include MOCNESS1. These data were collected by Dr Carin J. Ashjian and Dr Peter H. Wiebe of Woods Hole Oceanographic Institution as part of the "GLOBEC: Winter Distribution and Success of Southern Ocean Krill (Southern Ocean Krill)" and "U.S. GLOBEC Southern Ocean (SOGLOBEC)" projects and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2023-01-23.
The following is the text of the dataset description provided by BCO-DMO:
Zooplankton abundance + stages from MOCNESS nets, NBPalmer
Dataset Description:
Zooplankton Abundance Based on Taxa and Life Stages or Size Classes, Collected during the Broadscale NB Palmer Cruises, Austral Autumn 2001 and 2002
The MOCNESS-1 plankton sampler has nine rectangular nets (1m x 1.4 m) with a mesh size of 0.333 mm, which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al., 1976).
Note: NBP0104 tows 1-11 used a 500 micron mesh for net 1 samples. Then it was moved to net 0 for the remainder of tows.
Cruises:
Nathaniel B. Palmer, April-June 2001 (NBP01-03), 24 tows
Nathaniel B. Palmer, July-Sept. 2001 (NBP01-04), 17 tows
Nathaniel B. Palmer, April-May 2002 (NBP02-02), 24 tows
Nathaniel B. Palmer, July-Sept. 2002 (NBP02-04), 19 tows

Supplemental Information | Acquisition Description: Zooplankton abundance, vertical and horizontal distribution, and population structure were assessed using a 1 m^2 Multiple Opening and Closing Nets and Environmental Sampling System (MOCNESS) with nine nets having 333 um mesh and environmental sensors of temperature, salinity and depth. The entire water column was sampled on the downcast using net # 0, which was not analyzed here. The water column was typically sampled from close to the bottom at stations on the shelf where depths were less than 1000 m, or to 1000m at stations off the shelf where depths were often from 3000 to 4000 m. Nets 1 through 8 sampled from various depth intervals to the surface with smaller strata near the surface. Several tows targeted krill swarms by towing in a single strata. Approximate locations of broadscale study stations are shown in Figs. 1-4, below. Zooplankton samples were immediately preserved in 5% buffered formalin solution. In 2006, the samples were sent to the Atlantic Reference Centre, Huntsman Marine Science Centre, St. Andrews, New Brunswick, Canada to be sorted. All the large organisms (>15 mm) in the sample were removed and identified to taxa. The sample was then split to about 100 individuals of euphausiids. All euphausiids in the split were identified to species and life history stage. Next, the sample was split to about 100 individuals of copepods. Copepods were identified to species and life history stage (female, male, copepodite V, or other copepodite). All other zooplankton in the split were identified to taxa and counted. For the Euchaetidae, we followed the designation of Park (1994) who ascribed the Antarctic species to the genus Paraeuchaeta. This data object ('zooabund_nbp') reports the counts of zooplankton per subsample/split by taxa and life stage or size class. The companion data object 'zooabund_lmg' reports similar for the MOCNESS samples collected on the L.M. Gould cruises and data object 'krill' reports the abundance of each euphausiid species by life stage and size class, also on the L. M. Gould. Displacement volume measurement: Entire sample plus liquid was measured in a large graduated cylinder then poured through a sieve into a second cylinder. The difference in volume is the displacement volume. Greenwich Mean Time was local time + 4 hours. Fig. 1.
