These data were handed to the Australian Antarctic Data Centre as an ancillary dataset. This metadata record was created by AADC staff many years after the voyage concluded. Times and locations were recorded from the ship's GPS. A collection of data files detailing visual sightings of krill swarms on the sea surface from the Aurora Australis during the BROKE-West voyage, 2005-2006. These data were additional data collected by whale observers. See the record, "BROKE-West_Cetaceans" for full details on the process of collecting whale observations. In summary though, observers were present from the time the vessel departed Fremantle until it approached Hobart. Observers worked whenever light, weather and sea conditions permitted. Generally between two and five observers were working at any given time (see the above cetaceans metadata record for more information). The download file contains: - GIS shapefiles showing the locations of the recorded swarms on the ship's track. - A csv and Excel file of the recorded observations. - Several map images showing the ship's track and the observed swarms. The BROKE-West survey was conducted on voyage 3 of the Aurora Australis during the 2005-3006 season. It was intended to be a comprehensive biological and oceanographic survey of the region between 30 degrees and 80 degrees east.
