What is natural? Humans, megafauna and climate in northern Australia. This project aims to produce the first long-term (100,000 year), replicated, high-resolution terrestrial records of environmental change before, during and after the arrival of humans in Australian savannas. These records will be the first in the world to extract, from the same material, independent, cutting-edge organic and isotope geochemical records of changes in water balance, vegetation type and fire activity. This will enable natural and human drivers of change in northern Australia's climate and biodiversity to be disentangled on two timescales: millennial: before, during and after Aboriginal arrival in northern Australia and centennial: before, during and after European arrival in northern Australia.

什么是自然的？澳大利亚北部的人类、巨型动物和气候。该项目旨在制作第一个长期（100,000 年）、复制的高分辨率陆地记录，记录人类抵达澳大利亚稀树草原之前、期间和之后的环境变化。这些记录将是世界上第一个从相同材料中提取有关水平衡、植被类型和火灾活动变化的独立、前沿的有机和同位素地球化学记录的记录。 这将使澳大利亚北部气候和生物多样性变化的自然和人类驱动因素在两个时间尺度上得到解决：千禧年：原住民到达澳大利亚北部之前、期间和之后；百年：欧洲人到达澳大利亚北部之前、期间和之后。
