Zooplankton Sampled with 10m2MOCNESS Net in Georges Bank 1995-1999Entry ID: MOC10GB
Abstract: Zooplankton populations were monitored on a monthly basis (Jan-Jun), years 1995-1999, for a total of thirty cruises. Plankton tows were made using a MOCNESS 10 system with 5-6 (10 m^2) nets having 3.00-mm circular mesh. Nets are opened and closed sequentially by commands through conducting cable from the surface. Organisms are identified at the species level. Abundance is calculated. In a ... companion file, length data are reported at the species level (see related URLs). Environmental data (CTD sensor package appended to the MOCNESS) are reported in an ancillary object/file (see related URLs).
1. The catch from each net was sub-sampled and all animals in the sub-sample were counted.
2. Due to the shear volume of data, only those animals found were represented in these on-line data, i.e. no animals with zero abundance were listed.
3. The precision variation in the latitude and longitude numbers is as reported.
4. Not all nets for all tows are represented here. Some nets came back empty.
5. See the companion file containing the moc10data length measurements of the organisms screened at http://globec.whoi.edu/jg/serv/globec/gb/moc10data_lengths_rs.html0...

Purpose: The Biological and Chemical Oceanography Data Management Office (BCO-DMO) was created to serve PIs funded by the NSF. BCO-DMO manages oceanographic scientific research data contributed by the originating principal investigators. The BCO-DMO data system facilitates data stewardship, dissemination, and storage. The main BCO-DMO objective is to support the scientific community through improved access ... to ocean science data.
U.S. GLOBEC (GLOBal Ocean ECosystems Dynamics) is a multi-disciplinary research program designed by oceanographers, fishery scientists, and marine ecologists to examine the potential impact of global climate change on ocean ecosystems. The objective of U.S. GLOBEC studies on Georges Bank is to understand how changes in environmental conditions affect the dynamics of the target copepod and fish (cod and haddock) species.
