This project aims to design and execute autonomous observations above (unmanned aerial vehicles), below (autonomous underwater vehicles) and within (wave-ice interaction buoys) sea ice on international Antarctic research voyages. The project intends to advance the parameterisation of wave-ice interaction, critical to the seasonal advance and retreat of Antarctic sea ice, in climate models that do not reproduce the observed trends in regional Antarctic sea ice extent. The project expects to improve prediction of sea ice’s responses and feedbacks to changes in ocean and atmospheric forcing around the Southern Ocean. This work should place Australia at the forefront of polar climate research. Greater accuracy in climate projections will help to optimise the balance between human populations, economic growth and environmental protection in an uncertain future.

本项目旨在设计和实施国际南极科考航行中海冰上（无人机）、水下（自主水下航行器）和海冰内（波冰相互作用浮标）的自主观测。该项目打算在气候模式中推进波冰相互作用的参数化，这对南极海冰的季节性进退至关重要，但不能再现观测到的南极海冰区域范围的趋势。该项目希望改进对海冰对南大洋周围海洋和大气强迫变化的反应和反馈的预测。这项工作将使澳大利亚处于极地气候研究的前沿。在不确定的未来，提高气候预测的准确性将有助于优化人口、经济增长和环境保护之间的平衡。
