The award is for a collaborative study involving the Universities of Colorado, Oregon, Washington, and Alaska, aimed at improving the understanding of the characteristics, mechanisms, and feedback processes associated with changes in vegetation, sea level, and standing surface water in Beringia during the last 21,000 years, and to use this understanding to aid in the development of predictive tools for future pan-Arctic climate change. The specific research objectives and tasks are based on refining a modeling strategy for simulating regional paleoclimatic variations and for diagnosing the interactions between different components of the climate system, utilizing global and regional climate models and an equilibrium vegetation simulation model. Simulations will be performed at key times, compared to observational data, and diagnosed to understand potential feedbacks.

该奖项旨在表彰科罗拉多大学、俄勒冈大学、华盛顿大学和阿拉斯加大学的一项合作研究，旨在提高对过去21000年来白令陆桥植被、海平面和地表水变化的特征、机制和反馈过程的理解，并利用这一理解来帮助开发预测未来泛北极气候变化的工具。具体的研究目标和任务是基于完善模拟区域古气候变化和诊断气候系统不同组成部分之间相互作用的建模策略，利用全球和区域气候模式和平衡植被模拟模式。模拟将在关键时刻进行，与观测数据进行比较，并进行诊断以了解潜在的反馈。
