Novel dating methods for marine sediments of relevance to determining past climate changes

未来的气候变化是当代人们广泛关注的一个话题，对人类的经济和社会影响巨大。然而，准确了解过去的气候对于了解全球气候未来如何演变至关重要。该提案旨在开发利用宇宙成因同位素测定海洋沉积物年代的新方法，以提取锁定在这些沉积物中的古气候信号。我们将重点关注对世界气候起着至关重要作用的南大洋。该提案还将有助于履行澳大利亚在这一关键领域开展研究的国际义务。

Future climate change is a subject of enormous contemporary interest with economic and social implications for much of humanity. Accurate knowledge of past climates is, however, crucial to understanding how the global climate will evolve into the future. This proposal aims to develop novel methods for dating marine sediments using cosmogenic isotopes, in order to extract the palaeoclimatic signals that are locked into these sediments. We will concentrate on the Southern Ocean which plays a crucial role in the world's climate. This proposal will also contribute to Australia's international obligation to conduct research in this critical area.
