Krill and zooplankton demography during K-AxisDistribution and abundance of zooplankton, krill and fish were observed on the K-axis transect using deployments of RMT1+8 net. Towing speed of the RMT1+8 were approximately 2 knots. All krill, fish and squid in the catch were sorted, identified to species and counted. The density at each station were determined from the counts per calibrated flow-meter readings attached to the net. Morphometric m

Zooplankton abundance in the Kerguelen Axis regionZooplankton were collected with a Rectangular Midwater Trawl (RMT 8+1 net) from 37 sampling sites on and near the Southern Kerguelen Plateau. The contents of each net were preserved in 5% buffered formaldehyde. This dataset covers the counts of the contents of the RMT1 net. The contents were split in the laboratory using a Motoda Box and then identified and counted under a Leica M165C stereo-micro

Thysanoessa macrura: life history parameters and lipid profilesZooplankton were collected with a Rectangular Midwater Trawl (RMT 8+1 net) from 37 sampling sites on and near the Southern Kerguelen Plateau. Specimens of the euphausiid Thysanoessa macrura were selected for cohort analysis, based on lengths, and allometry (dry weights and lengths). Lipids were extracted from the animals to provide a lipid content (%) as a function of dry weight. A small number of

CTD Data from the Rectangular Midwater Trawl collected during the BROKE-West voyage of the Aurora Australis, 2006The CTD data were acquired when the RMT instrument was in the water. Data Acquisition: There is a FSI CTD sensor housed in a fibreglass box that is attached to the top bar of the RMT. The RMT software running in the aft control room establishes a Telnet connection to the aft control terminal server which connects to the CTD sensor using various hardware connections. Included are the calibration da
