0001pal/zodtrawl - Measurements of the length frequency distributions and condition factor measurements of the krill populations in the Palmer Basin region yield information on seasonal changes in the demographics of the krill population (on/offshore movements) and in the physiological condition of the krill. In conjunction with the bioacoustics determinations of biomass the data characterize the abundance and size character of krill in this nearshore region throughout the season. Krill are collected for these measurements by SCUBA divers and with a net towed from a zodiac. Zodiac trawls and dive operations are conducted in the immediate Palmer area within 3.7 km of the station (Palmer grid; Waters and Smith, 1992.) This data set contains a record of dives, zodiac trawls and dip nets to collect krill, and what was done with the catch. ( zodtrawl.list )
