meso_grazing

 PI:             Hans Dam
 dataset:        Mesozooplankton grazing rates 
 project/cruise: EQPAC/TT007
 ship:           Thomas Thompson

 These data represent weight-specific grazing rates of
 mesozooplankton as a function of latitude, depth and size fractions
 of animals for the Survey cruises of the EqPac study.

 Grazing was measured with the gut fluorescence technique. Details
 are given in the EqPac Protocols.  Mean GCRC (gut clearance rate constant)
 of this cruise (0.036/min) was used.
