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极感兴趣的主题，对人类的大部分人都有经济和社会影响。然而，对过去气候的准确了解对于理解全球气候将如何演变到未来至关重要。这项提议旨在开发利用宇宙成因同位素测定海洋沉积物年龄的新方法，以提取锁定在这些沉积物中的古气候信号。我们将集中关注对世界气候起着关键作用的南大洋。这项提议还将有助于澳大利亚履行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.
