This dataset contains the underway data from Voyage 2 1990-91 (ICE) of the Aurora Australis. Unfortunately, these data are corrupt and may not be able to be recovered. They are therefore not available online. This was a resupply voyage, but marine science data were logged as part of the sea trial to test the DLS. DLS data types were logged at 20-second intervals. The observations were taken between October and November 1990 en route from Hobart to Casey to Mawson to Davis and back to Hobart.
These data are corrupt and may not be able to be recovered.
Where data for a particular sensor do not exist for a particular time, the last known value is used unless the sensor has been disabled or has encountered an error. For example, some sensors only record data every minute, but the resolution for the underway dataset is 10 seconds, so the same value will be used 6 times a minute. No averages are taken for sensors that capture data at a rate other than every 10 seconds. Instead, each record will be a snapshot of each sensor at that time.
Data are stored on Magnetic Optical Disk and are not available online.
