Dataset acquisition description

   PI:              Hans Dam
   of:              University of Connecticut
   dataset:         Mesozooplankton weight-specific carbon ingestion rates
   dates:           April 25, 1989 to May 31, 1989
   location:        N: 47.0553  S: 46.265  W: -20.251  E: -17.6567
   project/cruise:  North Atlantic Bloom Experiment/Atlantis II 119, leg 4 and 5
   ship:            R/V Atlantis II
 
   Methodology
 
   See:  Dam, Hans G., Carolyn Miller and Sigrun Jonasdottir, 1993.  The trophic
   role of mesozooplankton at 47N and 20W during the North Atlantic Bloom
   Experiment.  Deep-Sea Research II, Vol. 40, N0. 12 pp 197-212.
 
   DMO Note:
 
   The reporting of plankton tow events was inconsistent, event numbers
   may reference a single tow or a series of tows.  Use caution in a
   merging of data from different sources.

Instruments

Mechanical Flowmeter

Supplied Description:

A General Oceanics flowmeter mounted at the mouth of the net and a filtering cod end (mesh size 0.2 mm).

Instrument Type

Generic Name: Mechanical Flowmeter

Generic Description:

Manufactured by General Oceanics, a mechanical flow meter is used with plankton tows to determine the volume of water which flows through the net. Flow meters are also used in rivers, estuaries, canals, sewer outfalls, pipes, and harbor entrances to determine water velocity and flow distance information.

Ring Net

Supplied Name: RingNet

Supplied Description:

a 1 meter ring net fitted with a 0.2 mm mesh

Instrument Type

Generic Name: Ring Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic Description:

A Ring Net is a generic plankton net, made by attaching a net of any mesh size to a metal ring of any diameter. There are 1 meter, .75 meter, .25 meter and .5 meter nets that are used regularly. The most common zooplankton ring net is 1 meter in diameter and of mesh size .333mm, also known as a 'meter net' (see Meter Net).
