Brief description

The New Zealand Defence Force (NZDF) has established a permanent wave observation station near Campbell Island, south of New Zealand (52 45.71 S, 169 02.54E). The site was chosen for logistical convenience and its unique location adjacent to the highly energetic Southern Ocean; allowing instrumentation typically deployed on the continental shelf to be used in this rarely observed southern environment.

From February 2017, a Triaxys Directional Wave Buoy was moored in 147 m depth, some 17 km to the south of the island, with satellite telemetry of the 2D wave spectra at 3-hourly intervals. To date there have been three deployments on locations, yielding some 784 days of data. Validation of the measured significant wave height against co-located satellite altimeter observations suggests that the predominant wave directions are not attenuated by the island. The data provide a valuable record of the detailed wave spectral characteristics from one of the least-sampled parts of the Global Ocean.

This and future data will also be accessible via the "Waverider buoys Observations - Australia - delayed (National Wave Archive)" collection available through the Australian Ocean Data Network Portal (https://imos.aodn.org.au/imos123/home?uuid=%202807f3aa-4db0-4924-b64b-354ae8c10b58), the main repository for marine data in Australia. The data represented by this metadata record is a snapshot of the NZDF data at the time of this publication (03/08/2021), and has been assigned a DOI and will be maintained in perpetuity by the AODN.
