Underway voyage data collected from Australian Antarctic Division chartered shipsEntry ID: underway_ship_data
Click to see members of this collection.
Abstract: Australian Antarctic Division chartered vessels routinely collect environmental information as they move around the Southern Ocean. The type of data collected varies depending on the vessel (and exactly what sensors are in place on each ship).
Underway data typically include a number of meteorological and oceanographic parameters (such as sea surface temperature, air temperature, humidity, UV ... levels, water depth, salinity, etc) as well as ship parameters (such as heading, speed, position, etc).
Data can typically be extracted via the Marine Science Underway Data Tool, available at the URL given below. Data can be extracted in various formats (such as text, excel, netcdf) and in various permutations.
Underway data collection began in 1985 on the Nella Dan.
See all the child metadata records for detailed information on each cruise.
The Entry_IDs of the child metadata records can be interpreted as follows:
198586 - Antarctic season 1985/1986
010 - voyage number - in this case voyage 1. The trailing 0 is present in case a voyage was conducted in more than 1 cruise, as was the case for 198990072.

Difficulties affecting project:
Because of logistical delays to the Aurora Australis shipping schedule, ship time for this project was deferred to the 2009/2010 season. Thus we have not done any of the sampling for the project.
Taken from the 2009-2010 Progress Report:
Variations to work plan or objectives:
The only variation in the work plan was that we were able to collect some non-calcifying planktonic invertebrates for the Australian Museum. These have already been donated to the Museum to contribute to to ongoing assessment and monitoring of biodiversity in the open Southern Ocean, an area where there is still little data.
As noted we collected plankton samples at eight Southern Ocean stations (complete station data below). The main collection tool was the Rectangular Midwater Trawl, using a 150-micron mesh in the RMT-1 frame, as most of the planktonic organisms we were targeting are between 150 microns and 1 mm.
Laboratory analysis has not yet commenced, as many of the samples are still being held by Biosecurity Australia in biological quarantine. For consistency of analytical method, we are trying to process all the samples as close to together in time as possible and using the same sets of reagents and processing techniques, in order to reduce any variability introduced by laboratory processing.
