This award will use funds made available under the auspices of the Small Grants for Exploratory Research (SGER) program to deploy an experimental and mobile coring apparatus to obtain ice cores from an alpine site atop Mt. Waddington in the British Columbia Coast Range. The site holds the promise, but not the certainty, of obtaining a continuous record of inter-annual variability in net annual snowfall over the last 200-1,000 years. This is important because if the drill works as planned, it will open up a new archive of paleoclimate data to use by climate researchers. At present, most paleoclimate research from ice cores is conducted from large base stations in polar regions. Annual snow accumulation records, which can be well preserved even in areas with significant summer melt-layer formation, have been shown to be useful quantitative indicators of large-scale atmospheric circulation patterns. Snow accumulation records from the North Pacific region are of particular interest because of their potential to contribute to the documentation and reconstruction of multi-decadal climate variability. The ice divide at Combatant Col, below the summit of Mt. Waddington, contains approximately 150 meters of ice and rarely experiences melt at the surface.The funds from this award will be leveraged against funds from the Canadian Foundation for Climate and Atmospheric Sciences (CFCAS), who will bear the majority of the expedition costs (i.e., helicopter support, drill shipment, drill preparations and repair) and provide satellite imagery and analysis, installation of a weather station near Mt. Waddington, mesoscale climate modeling, and glacier ice flow modeling. The co-funding between the US NSF and the CFCAS is an attractive feature of this SGER request because it effectively leverages US funds to derive a bigger bang for the US buck.Besides field testing a new strategy in ice core drilling that could have broad impact on the wider science community, the data from project will aid in the quantitative reconstruction of climate variability in western North America and the North Pacific as well as improved understanding of glacier mass balance and hydrological variability.

该奖项将使用小额赠款的主持人提供探索性研究（SGER）计划的资金来部署实验性和移动的加油设备，以从不列颠哥伦比亚省海岸山脉沃丁顿的高山站点获得冰芯。该地点具有在过去200 - 000年中获得年净降雪量净降雪的持续记录的诺言，但没有确定性。 这很重要，因为如果演习按计划工作，它将为气候研究人员使用新的古气候数据档案。 目前，大多数来自冰核的古气候研究都是从极地地区的大型基站进行的。年度积雪记录，即使在具有明显的夏季熔融形成的地区也可以保存得很好，但已被证明是大规模大气环流模式的有用定量指标。 来自北太平洋地区的积雪记录特别令人感兴趣，因为它们有可能有助于多年气候变化的文档和重建。 在瓦丁顿山顶下方的战斗col处的冰划分，大约有150米的冰，很少经历在表面上融化。该奖项的资金将由加拿大气候和大气科学基金会的资金（CFCAS（CFCAS）的资金供应（CFCAS），并提供了训练的大部分训练，并提供了训练的大部分（i。图像和分析，沃丁顿山附近的气象站安装，中尺度气候建模以及冰川冰流建模。 美国NSF与CFCA之间的共同汇款是该SGER请求的一个吸引人特征可变性。
