Zooplankton Abundance Based on Taxa and Life Stages or Size Classes, Collected during the Broadscale NB Palmer Cruises, Austral Autumn 2001 and 2002

The MOCNESS-1 plankton sampler has nine rectangular nets (1m x 1.4 m) with a mesh size of 0.333 mm, which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al., 1976).
Note: NBP0104 tows 1-11 used a 500 micron mesh for net 1 samples. Then it was moved to net 0 for the remainder of tows.

Zooplankton Abundance and biomass from MOCNESS nets using silhouette analysis
NB Palmer, austral fall & winter of 2001 & 2002 - Biomass (wet weight) and abundance were determined principally by silhouette digitization of taxa lengths and conversion to equivalent wet weights according to the equations and methods adapted from Davis and Wiebe (1985) and Wiebe et al. (2004).
