Funding is provided to obtain new ice core accumulation records from Combatant Col, Mt. Waddington, in southwestern British Columbia (BC), Canada. Combatant Col is located significantly farther south than other existing ice core sites along the west coast of North America and variations in precipitation tend to be out of phase with those in Alaska and the Yukon. Combatant Col sits at 3000 meters and contains more than 200 meters of ice. The net annual snow accumulation is ~2.5 meters/year and the mean annual temperature -5°C. A 65-meter core from the site shows that clear annual layering is preserved in the geochemistry and in dust and black carbon. The age of the ice near bedrock is estimated to be between 200 years and 1000 years old. It is anticipated that an annually-resolved record of layer thickness will be recovered at the site to allow for a record of snow accumulation covering the last 200-1000 years.The Combatant Col record, in combination with other existing records of precipitation variability along the western margin of North America, will be used to develop an updated and improved reconstruction of precipitation variability in this region over the last 200-1000 years to address fundamental questions about Pacific decadal scale variability.The broader impacts involve supporting an early career female investigator and strengthening international collaborations with researchers from institutions in Canada.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

提供了资金，以获取加拿大不列颠哥伦比亚省西南部（BC）的Waddington的战斗人员上校获得新的Ice Core积累记录。战斗人员的Col比北美西海岸的其他现有冰核地点明显较远，而降水的变化往往与阿拉斯加和育空地区的冰核相同。战斗人员的Col位于3000米处，含有200多米的冰。净降雪量为〜2.5米/年，平均年温度为-5°C。该站点的65米核心表明，在地球化学和灰尘和黑碳中保存清晰的年度分层。据估计，基岩附近的冰年龄在200至1000年之间。预计预计将在现场恢复年度厚度的年度记录，以允许覆盖最近200 - 1000年的积雪记录。战斗人员的记录以及北美西部边缘沿西部边缘的其他现有精确变异性的其他现有记录将用于在最新的200年代范围内，以提高200-1000年度的范围，以提高范围的范围，以解决200-1000的规模，以确定规模的规模，以确保预测的规模，以确定预测的规定影响涉及支持早期职业女性调查员，并加强与加拿大机构的研究人员的国际合作。该奖项是根据2009年的《美国复苏和再投资法》（公法111-5）资助的。
