No problems were encountered with data collection. Zooplankton were collected during the winter-spring transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. To determine size and biomass, key species were measured. Measurements of Prosome, Urosome and Total length are provided. The zooplankton were taken from samples collected with umbrella nets, RMT1 net and sea ice cores. They were measured under a Leica M165C steromicroscope using an ocular micrometer. The ocular micrometer was calibrated against a stage micrometer (+/- 0.01 um). The lengths of the zooplankton were used in standard length/weight equations to determine biomass of the key species. The lengths were also used to calibrated measurements of biomass size spectra, as determined by the laser optical plankton counter (LOPC).
