Dr. Rebecca Barnes is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at the United States Geological Survey, Boulder. Dr. Barnes will examine the effects of coal bed methane (CBM) extraction in the chemistry of streams in the Powder River Basin, Wyoming. The research goals will be accomplished by examining the changes in nitrogen budgets and behavior in the semi-arid watershed. The investigation will be based on intensive sampling of stream waters, and field and laboratory experiments to determine changes in the nitrification rates. Chemical analyses of water will include ammonium concentrations and nitrogen and oxygen isotopes. These results will contribute to better understanding of the chemical effects of coal bed methane extraction on stream waters. The information can be used to inform decisions as new CBM extraction areas begin production.In addition, Dr. Barnes will collaborate with faculty from the University of Colorado - Boulder, Fort Lewis College and the Mountain Studies Institute in developing field based classes for members of the San Juan Mountains community to foster watershed literacy. This community was selected because there is potential for CBM extraction in the future.

丽贝卡·巴恩斯博士被授予美国国家科学基金会地球科学博士后奖学金，在博尔德美国地质调查局开展一项研究和教育计划。巴恩斯博士将研究煤层甲烷（CBM）提取对怀俄明州粉河流域溪流化学成分的影响。研究目标将通过研究半干旱流域氮收支和行为的变化来实现。调查将基于对溪水的密集取样，以及实地和实验室实验，以确定硝化速率的变化。水的化学分析将包括铵浓度、氮和氧同位素。这些结果将有助于更好地理解煤层气开采对河流水体的化学效应。当新的煤层气开采区域开始生产时，这些信息可用于为决策提供信息。此外，巴恩斯博士将与科罗拉多大学博尔德分校、刘易斯堡学院和山地研究所的教师合作，为圣胡安山脉社区的成员开发基于实地的课程，以培养流域素养。选择该社区是因为未来有开采煤层气的潜力。
