This dataset contains biological and survey - biological data collected on R/V Edwin Link, R/V Oceanus, and R/V Seward Johnson during cruises EL9904, EL9905, OC303, and SJ9508 from 1995-06-11 to 1999-05-29. These data include depth, sex, stage, and taxon. The instruments used to collect these data include Zooplankton Pump - gas centrifugal and Zooplankton Pump - gas powered diaphragm. These data were collected by Dr Lewis Incze of University of Southern Maine as part of the "U.S. GLOBEC Georges Bank (GB)" project 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 2019-02-21.

Zooplankton counts (density)

Dataset Description:
Zooplankton Densities/Abundance

Principal Investigator: Lewis S. Incze
Research Technicians: Ford Dye, Beth Novak, Nicholas Wolff

Methods:

Using a pumping system appended to the CTD unit, measured water volumes (typically 40 liters) were sampled at descrete depths and filtered through 40 micron mesh prior to sorting. A subsample of the filtered sample was used for the zooplankton counts and identification. The size of the subsample varied and depended on the amount of zooplankton present - subsamples were larger when there were fewer animals.

From the subsamples, all zooplankton were counted and identifed. Counts were then converted into number per cubic meter as follows: Number counted / (Subsample size X Amount filtered).

It is worth noting that the frequency of repeated densities is an artifact of the small subsample volumes screened in order to process a large number of samples. The small sample volumes did not give us the ability to resolve small differences in abundance at individual species and stages (e.g., Cal fin Nauplius I). At this level of sorting many counts were reported as zeros, ones, twos or threes. These counts are at the threshold for detection, and the results give the false impression of many identical densities (concentrations). This also shows up in gaps in the life histories as well. For example, a single depth/station might have NI and NIII and NIV stages, but not II or V. As a result, samples were often recombined to give the population characteristics of an integrated water column, or a group of samples. The approach worked well for our research objectives and we are well aware of its limitations. A single station and depth in our data can be deceiving and does not tell the whole story.

Note: Sampling for cruise EL9904, events EL10999.24 and EL111299.6 are intentional replication sites. All sampling was made at same depth level. These stations were used to test the repeatability of methods.
