| Summary: | Progress Code: completed Statement: Please see the Marine Science Support Data Quality and Programmer's Reports at 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 7.2 1989-90 (HIMS) of the Aurora Australis. This was the maiden cruise of the AA and was a manned marine science voyage. DLS data types were logged at 60-second intervals. The observations were taken between May and July 1990 en route from Hobart to Heard Island and back to Hobart. The Programmer's and Data Quality Reports are available via the Related URL section. Also available is a scan of a printed plot of a section of the Voyage 7.2 1989/90 (HIMS) track in the Heard Island area, 18 May to 14 June 1990.
