Science data collection by the New Zealand Defence Force during the 2022 Antarctic Resupply Mission

The maiden resupply voyage of HMNZS AOTEAROA to Winter Quarters Bay, McMurdo Sound, provided a vessel of opportunity to complete experimentation in the Ross Sea and Southern Ocean, focussed on improving maritime safety. The science programs on the voyage included the deployment of 21 free floating wave buoys, 10 Global Drifters, 2 Argo Floats and 85 expendable bathythermograph profilers. In addition, measurements of meteorological and oceanographic conditions and sea ice characteristics were captured from onboard the ship and augmented with satellite-based synthetic aperture radar captures and high-resolution wave modelling. An aligned experiment was also undertaken to assess the performance of Global Navigation Satellite Systems systems at high latitudes. The full set of voyage data and instructions for their access are described.
