meso_grazing

 PI:             Hans Dam
 dataset:        Mesozooplankton grazing rates 
 project/cruise: EQPAC/TT011
 ship:           Thomas Thompson

 Grazing was measured with the gut fluorescence technique. Details
 are given in the EqPac Protocols. Mean GCRC (gut clearance rate constant)
 of this cruise (0.032/min) was used.

 The grazing rates are the mean values of 2-5 pseudoreplicates from each
 tow.  Contact Hans Dam for additional pseudoreplicate values.
