| Summary: | Progress Code: completed Statement: Please 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 7 1992-93 (KROCK) of the Aurora Australis. This was a manned marine science voyage. The observations were taken between January and March 1993 on route from Hobart to Davis to Mawson to Casey and back to Hobart. DLS and NoQalms data types were logged. See the Marine Science Support Data Quality and Programmer's Reports at the Related_URL section. Also available is a scan of a printed plot of a section of the Voyage 7 1992/93 (KROCK) track: transects north of the Antarctic coastline between 60 degrees East and 83 degrees East, 15 January to 7 February 1993.
