| Summary: | Progress Code: completed Statement: See the Marine Science Support Data Quality Report via the Related URL section. 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. This dataset contains the underway data from Voyage 6 1990-91 (AAMBER2) of the Aurora Australis. This was primarily a marine science voyage. DLS data types were logged at 60-second intervals. The observations were taken between January and March 1991 en route from Hobart to Prydz Bay to Mawson to Davis and back to Hobart. Marine Science Support Data Quality and Programmer's Reports are available via the Related URL section. Temperature and salinity data from the CTD were also obtained. The fields in the CTD dataset are: pressure temperature salinity volume geopotential
