Sea ice which is held motionless against the Antarctic coastline (so-called landfast, or 'fast' ice) is hugely important for global climate and Southern Ocean ecosystems but its extent has recently plummeted. This project will address major knowledge gaps by providing novel satellite-based mapping and analysis of fast ice extent, towards enabling incorporation of fast ice into Australia’s new sea ice-ocean Earth system model for the first time – to allow assessment of its impacts on global ocean circulation and ice shelf melt. Outcomes also include new automated capability for monitoring fast ice extent, analysis of its variability and drivers, and first maps of its thickness and roughness.

对南极海岸线（所谓的Landfast或“快速”冰）一动不动的海冰对全球气候和南方海洋生态系统非常重要，但其范围最近暴跌。该项目将通过提供基于卫星的新型映射和快速冰范围的分析来解决重大知识差距，从而使快速冰的保险首次进入澳大利亚新的海冰海洋地球系统模型，以评估其对全球海洋循环的影响和冰架融化。结果还包括用于监测快速冰范围的新自动化能力，对其可变性和驱动因素的分析以及其厚度和粗糙度的第一张地图。
