Description

This dataset contains the underway data from Voyage 1 1997-98 (WANDER) of the Aurora Australis. This was a manned marine science cruise. This is the first AA voyage to use the new Java-based NOODLES logging system. See the Voyage Leader's, Marine Science Support Data Quality and Programmer's Reports at the Related URL section.

CTD and XBT data were also obtained on this voyage.

From the Voyage Leader's Report:

RSV Aurora Australis came on charter for the 51st ANARE and the first voyage of the 1997-98 season on 8 September, and sailed from Selfs Point for Macquarie Island at 2100 on the 9th. The vessel anchored in Buckles Bay at 0810 on 13 September after a moderately rough passage that included the conducting of a test CTD. The approach (and departure) route conformed with a request from ANAREMAIC to cover areas devoid of bathymetric cover.

Four IRBs transferred expeditioners and cargo. Three of the boats were crewed by station personnel - the fourth by Andrew McEldowney and Jon Reeve. Operations were completed at 1430. Among the more unusual RTA items backloaded was a racing pigeon that had flown from Devonport to the island three weeks earlier.

On leaving Macquarie Island, the vessel headed west to 54 S, 141 30 E, the site of the first of give SubAntarctic Zone Oceanography (SAZ) moorings to be deployed on the cruise (au9701). The passage was rough and the vessel's resulting slow progress generated concern that there would be insufficient time to deploy all the SAZ moorings and RTA on the specified date. A few of the 1000m CTDs originally scheduled for every degree of latitude were omitted in order to ensure that sufficient time would be available for the final moorings. Both engines were engaged to make up time between stations, and contingency planning allowed for the repositioning of the final mooring closer to Hobart, at 42 S instead of 43. This relocation proved unnecessary as the time allocated in the shipping schedule for the moorings and bathymetric surveys of each site proved to be unusually generous.

Quality

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.

Access

Data are available online via the AADC web page. A "supplementary" dataset is also available for download from the provided URL. It contains raw data collected directly from the ship, which has not been quality checked.
