The puzzle of landfast sea ice: ‘Fast’ ice and near-term climate impacts.

在南极海岸线上静止不动的海冰（所谓的陆地固定冰，或“快速”冰）对全球气候和南大洋生态系统非常重要，但其范围最近急剧下降。该项目将通过提供新的基于卫星的快速冰范围测绘和分析来解决主要的知识空白，从而首次将快速冰纳入澳大利亚新的海冰-海洋地球系统模型，从而评估其对全球海洋环流和冰架融化的影响。结果还包括新的自动化能力，用于监测快速冰的范围，分析其变化和驱动因素，以及首次绘制其厚度和粗糙度图。

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.
