A database containing sounding data around Macquarie Island. Track line data for each data source is included.

Echosounder data were collected on a multidisciplinary research voyage conducted from the RV Tangaroa, operated by New Zealand’s National Institute of Water and Atmospheric Research Limited (NIWA). The voyage lasted 42 days, departing from Wellington, New Zealand on January 29th , 2015 and returning to the same port on 11th March 2015. Active acoustic data were obtained continuously using a calibrated scientific echosounder (Simrad EK60, Horten, Norway). The echosounder operated at 38 and 120 kHz for the duration of the voyage with a pulse duration of 1.024 ms, a pulse repetition rate of one ping per second and a 7° beam width. The echosounder data here are a subset of that collected throughout the voyage and include only data from south of 65°S. This subset of data focuses on research questions pertaining to Antarctic blue whales and krill.

The data processing was done by the Royal Australian Navy's (RAN) Deployable Geospatial Support Team (DGST) and was provided to the Australian Antarctic Data Centre by the Australian Hydrographic Office. The dataset is titled HI513. The data was processed was collected on the following voyages: 1997/98 V2, V4, V6 1998/99 V1, V4, V5 2003/04 V1, V3, V7, V9 2004/05 V4, V5 2005/06 V2, V5 2006/07 V1, V2 2007/08 V1, V2, V3, V5, V6 2010/11 V3, V4, V5 2011/12 V1, V2, V3, VE1 The data has not been through the verification process for use in charts.

On every voyage of the Aurora Australis, approximately 50 onboard sensors collect data on average every 10 seconds. These data are known as the underway datasets. The type of data collected include water and air temperature, wind speeds, ship speed and location, humidity, fluorescence, salinity and so on. For the full list of available data types, see the website. These data are broadcast "live" (every 30 minutes) back to Australia and are available via the Australian Oceanographic Data Centre's portal (see the provided link). Once the ship returns to port, the data are then transferred to Australian Antarctic Division servers where they are then made available via the Marine Science Data Search system (see the provided URL). This dataset contains the underway data collected during Voyage 5 of the Aurora Australis Voyage in the 2011/12 season. Purpose of voyage: Recover Davis and Casey summer personnel Underway (meteorological) data are available online via the Australian Antarctic Division Data Centre web page (or via the Related URL section).
