This award is to support research that will develop new and extend existing tree ring records from the North Pacific Rim. These data will be analyzed to provide multi-century time series of coastal and oceanic conditions.Field work will be undertaken to collect samples from northern Alaska, Canada, Russia and northern Japan during the first two years of the study. Ring width measurements will be cross-dated visual, graphical and computer assisted techniques. Tree ring data generated during this project will be used to evaluate several climate indices and reconstruct North Pacific sea surface temperatures.The broader impacts of this proposed research are that it will lead to a better understanding of natural climate variability for the North Pacific region which in turn is critical for identifying anthropogenic signals in the short instrumental climate records. This information will help the community understand future climate change scenarios.

这一奖项是为了支持将开发新的和扩展北太平洋地区现有年轮记录的研究。这些数据将被分析，以提供几个世纪以来沿海和海洋条件的时间序列。在研究的头两年，将进行实地工作，从阿拉斯加北部、加拿大、俄罗斯和日本北部收集样本。环宽测量将是交叉日期的视觉、图形和计算机辅助技术。在这个项目中产生的树轮数据将被用来评估几个气候指数和重建北太平洋海面温度。这项拟议研究的更广泛的影响是，它将导致更好地了解北太平洋地区的自然气候变异性，这反过来对于在短期的仪器气候记录中识别人为信号至关重要。这些信息将帮助社区了解未来气候变化的情景。
