This award provides partial support for the acquisition of two major equipment items: (1) a Carbon-Nitrogen analyzer, and (2) an ion chromatograph. The instrumentation will be installed in a new laboratory at The Woods Hole Research Center (WHRC). The instruments all share the common focus of enhancing analytical capacity to study nitrogen (N) cycling processes in terrestrial and aquatic ecosystems. In addition, the capability for analyzing ammonium and nitrate in soil solutions and stream water will be enhanced. These instruments will also facilitate studying the efficacy of the denitrifying wastewater system at WHRC's new building and facilitate development of new projects. The research projects that will be advanced by acquisition of this instrumentation are directly relevant to important societal concerns regarding the health of forests that are experiencing increasing loads of N in atmospheric deposition, increasing climatic stresses, and increasing risks of deforestation.

该合同为采购两个主要设备项目提供部分支持：（1）碳氮分析仪，（2）离子色谱仪。 这些仪器将安装在伍兹霍尔研究中心（WHRC）的一个新实验室里。 所有这些仪器都有一个共同的重点，即提高分析能力，研究陆地和水生生态系统中的氮循环过程。 此外，还将提高分析土壤溶液和溪流中铵和硝酸盐的能力。 这些仪器也将有助于研究WHRC新大楼的污水处理系统的效率，并促进新项目的开发。 将通过收购这种仪器来推进的研究项目与重要的社会问题直接相关，这些问题涉及森林的健康，这些森林正在经历大气沉积中N负荷的增加，气候压力的增加以及森林砍伐的风险增加。
