The development of a reliable method for accurately determining the age of fossil shells represents a breakthrough in the ability to date marine shoreline, lake, and other shell-bearing deposits (e.g. middens). This will present new opportunities for research of significant national benefit, particularly into the effects of climate change, including linked sea-level change and melting of ice sheets, the impact of sea-level change on coastal zones, and shifts in the amount and variability of rainfall in different regions. The method may also be used to estimate the frequency and size of large storm and tsunami events, earthquake risk, and the timing of prehistoric human migration and associated environmental impacts.

一种可靠的方法的发展，可以准确地确定化石贝壳的年龄，这代表了测定海洋海岸线、湖泊和其他含贝壳沉积物（如贝壳）年龄的能力的突破。这将为具有重大国家利益的研究提供新的机会，特别是在气候变化的影响方面，包括与之相关的海平面变化和冰盖融化、海平面变化对沿海地区的影响以及不同地区降雨量和变率的变化。该方法还可用于估计大风暴和海啸事件的频率和规模、地震风险以及史前人类迁移的时间和相关的环境影响。
