Site Location: Georges Bank, Northeast US coast
Site(s) Georeferenced: Yes
Timespan: 1995 - 1999
Sampling Frequency: monthly (Jan-June); total 30 cruises
Data Collection Summary / Methods: 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.
Data collected: species id, abundance, length
OBIS data schema: species name, individual count, date, location, temperature, depth, salinity, nitrogen, oxygen, silicate.
Known Issues: 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. Not all nets for all tows are represented here. Some nets came back empty.
