054082HoodThis grant supports acquisition of a laser cavity optical spectrometer (LCOS) capable of rapid analysis of stable isotope ratios of Hydrogen and Oxygen in natural waters. The instrument will support NSF funded research on the effects of mountain glacier retreat proximal to the Gulf Alaska on hydrologic processes and ecosystem biogeochemical cycling across the cryosphere ? marine interface with a focus on stream processes in the wake of retreating glaciers. Recent climate warming in this region is dramatically altering local ecosystems as land is freshly exposed to atmospheric, hydrologic and biosphere activity. The effects of these processes have significant implications for important marine and freshwater fisheries, for sea level change and for the transport and fate of atmospheric aerosols. The LCOS will be particularly useful for determining the relative contribution of glacial melt waters to local streams. The PIs plan to engage in related K-12 outreach through an established summer short course series. The University of Alaska Southeast (UAS) in Juneau hosts a high percentage of Native Alaskans and UAS is an undergraduate institution. The potential impact for training underrepresented students in modern geochemical analysis method as applied to local environmental issues is high. ***

054082 Hood该拨款支持购买激光腔光谱仪（LCOS），该光谱仪能够快速分析天然沃茨中氢和氧的稳定同位素比率。 该仪器将支持NSF资助的研究，研究阿拉斯加湾附近山区冰川退缩对整个冰冻圈水文过程和生态系统地球化学循环的影响。海洋界面，重点是冰川退缩后的河流过程。 该地区最近的气候变暖正在极大地改变当地的生态系统，因为土地刚刚暴露在大气、水文和生物圈活动中。 这些过程的影响对重要的海洋和淡水渔业、海平面变化以及大气气溶胶的迁移和归宿具有重大影响。 LCOS将特别有助于确定冰川融水沃茨对当地河流的相对贡献。 PI计划通过既定的夏季短期课程系列参与相关的K-12推广活动。 位于朱诺的阿拉斯加东南大学（UAS）拥有很高比例的阿拉斯加原住民，UAS是一所本科院校。 对代表性不足的学生进行现代地球化学分析方法应用于当地环境问题的培训的潜在影响很大。 ***
