| Summary: | Progress Code: completed Statement: The data has been acquired at 0.1 Hz. There will be the occasional invalid values such as temperatures being out of range. This dataset has not been checked. Please verify the data before use. 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 data represents the total collection of acoustic, underway and satellite data collected on voyage 2 of the Aurora Australis in the 2003-04 season. For online access to the underway data for voyage 2 2003-04, see its specific metadata record, or the marine science database. The Acoustics data (ADCP) are in SIMRAD EK64 format (binary), and the echoview software is required to read them. The Underway data are in ASCII format. The Satellite Images are in TERASCAN format, and TERASCAN software is required to read them.
