This project aims to study the past 10 million years for unique signatures trapped in Earth’s deep ocean archives. It will investigate how and where the heavy elements are made in nature, and if nearby supernovae impacted on Earth. The project will provide a detailed time history of close-by supernova events. The set of radionuclide data can also be utilised for Earth’s climate record. The training included will provide qualified researchers for many fields, such as nuclear technology, nonproliferation, medical physics and nuclear safeguards, important for national security, health and economy.

该项目旨在研究过去1000万年来被困在地球深海档案中的独特签名。它将调查重元素是如何以及在哪里在自然界中形成的，以及附近的超新星是否撞击地球。该项目将提供附近超新星事件的详细时间历史。这套放射性核素数据还可用于地球气候记录。包括的培训将为许多领域提供合格的研究人员，如核技术、不扩散、医学物理和核保障监督，这些领域对国家安全、健康和经济都很重要。
