Samples were collected with a 1 m2, 335 um mesh MOCNESS at the following depth intervals: 0-50m, 50-100m, 100-150m, 150-200m, 200-300m, 300-400m, 400-500m, 500-750m, and 750-1000m. Plots were constructed from the midpoints of these intervals. Zooplankton were size-fractionated through a series of nested sieves (200um, 500um, 1000um, 2000um, and 5000um) and dried at 60oC to constant weight. A pair of MOCNESS tows was defined as one day tow and one night tow taken within 12h of one another.
