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（Rebecca Barnes）博士被授予NSF地球科学博士后研究金，以在博尔德（Boulder）的美国地质调查局（Bolder）进行研究和教育计划。 Barnes博士将检查怀俄明州粉末河盆地溪流化学的煤层甲烷（CBM）提取的影响。研究目标将通过检查半干旱流域中的氮预算和行为的变化来实现。该研究将基于对流域以及田间和实验室实验的密集采样，以确定硝化率的变化。水的化学分析将包括铵浓度以及氮和氧同位素。这些结果将有助于更好地理解煤层甲烷提取对溪流水的化学作用。这些信息可用于在新的CBM提取区开始生产时为决策提供信息。此外，Barnes博士将与科罗拉多大学 - 博尔德大学 - 博尔德大学，刘易斯堡学院和山区研究所的教职员工合作，以开发基于现场的班级，以供圣胡安山脉社区成员培养分水岭。之所以选择该社区，是因为将来有可能进行CBM提取。
