1126128HubenyThis Major Research Instrumentation grant supports acquisition a laser cavity ring-down spectrometer (LCRS) and a elemental analyzer front-end combustion device to support determination of the elemental concentrations of carbon, hydrogen, nitrogen, sulfur and oxygen and stable carbon isotope ratios of bulk organic matter in sediments, soils, tissues and natural waters. The requested isotopic and elemental analysis instrumentation would support PI and student research aimed at determining the provenance and pathways of organic matter transformation between reservoirs. Studies would range from paleoclimate investigations of lacustine archives to estuarine benthic metabolism dynamics in response to environmental changes. Salem State University (SSU) is a non-Ph.D. granting institution which historically has catered to first generation college students. Acquisition of this equipment represents a major infrastructural enhancement to the research capabilities of this regional college and will support a number of regional scientific users beyond campus.***

1126128 HubenyThis重大研究仪器补助金支持收购激光腔衰荡光谱仪（LCRS）和元素分析仪前端燃烧装置，以支持碳，氢，氮，硫和氧的元素浓度和沉积物，土壤，组织和天然沃茨中大量有机物的稳定碳同位素比的测定。 所要求的同位素和元素分析仪器将支持PI和学生的研究，旨在确定储层之间有机物转化的来源和途径。 研究范围从湖泊档案的古气候调查到河口底栖生物代谢动力学对环境变化的反应。 塞勒姆州立大学（SSU）是一个非博士学位。这是一个历史上为第一代大学生提供服务的机构。 购置这些设备是对该区域学院研究能力的重大基础设施改进，并将支助校园以外的一些区域科学用户。
