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.

该奖项是为了支持将开发新的并扩展北太平洋现有树环记录的研究。 这些数据将进行分析，以提供沿海和海洋状况的多世纪时间序列。在研究的前两年，将进行场外工作以从阿拉斯加北部，加拿大，俄罗斯和日本北部收集样品。 环宽度测量将是跨日期的视觉，图形和计算机辅助技术。 该项目期间产生的树环数据将用于评估几个气候指数并重建北太平洋海面温度。这项拟议的研究的更广泛影响是，它将更好地理解北太平洋地区的自然气候变异性，而这反过来又对在短时间的乐器气候记录中确定人为信号至关重要。 这些信息将帮助社区了解未来的气候变化方案。
