Aurora Australis Voyage V1 2007/08 (SIPEX) Track and Underway Data

Published: 2009-12-22

This dataset contains the underway data collected during the Aurora Australis Voyage V1 2007/08 (SIPEX). This voyage began in Hobart, and travelled to the ice edge where a large number of scientific observations were collected. Underway (meteorological) data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL section). See also other SIPEX metadata records. From the voyage leader's report: The Sea Ice Physics and Ecosystem eXperiment (SIPEX) was a multi-disciplinary science program focused on sea ice research in the region 115-130 E. There were 7 approved AAS proposals undertaken during the voyage: AAS 2901: PI: Dr Tony Worby (20 people) AAS 2767: PI: Klaus Meiners (18 people) AAS 2752: PI: Peter Ralph (2 people) AAS 2210: PI: Kelvin Michael (2 people) AAS 2100: PI: Graham Jones (2 people) AAS 1307: PI: Andrew McMinn (2 people) AAS 472: PI: Graham Hosie (1 person) The objectives of the voyage were to investigate the relationships between the physical sea ice environment and the sea ice biology, in particular the presence of algae and krill under the ice. A range of new instruments and techniques were used, including for the first time, radar and laser altimetry from helicopter for measuring the snow thickness and freeboard height above sea level. An instrumented Remotely Operated Vehicle (ROV) was used for making upward measurements of sea ice thickness and biomass concentration directly under the ice and a Surface and Under Ice Trawl (SUIT) was used for catching krill under the ice, clear of the ship's wake.
