Acquisition of Automated Carbon/Nitrogen Elemental Analyzer

海洋中碳和氮的元素分析 研究跨越了生物学、化学和 地质学，涉及多种样品类型，包括 实验室培养的微生物（例如细菌，浮游植物， 原生动物）和浮游动物生物量，水柱颗粒， 沉积物捕集器材料、表面微层样品和底栖生物 岩心样品 对于WHOI的科学家来说， 在浮游植物和细菌营养研究中的关键作用 动力学，初级生产力，水体营养循环， 微生物食物链动力学，水体颗粒物 热液喷口生物学以及 化学，石油地球化学，海气交换过程， 以及底栖生物与水柱的相互作用。 我们要求一个新的 CHN元素分析仪，将由不同的群体共享， 来自4个不同部门的WHOI科学家。

Elemental analyses of carbon and nitrogen in oceanographic research crosses the disciplines of biology, chemistry, and geology and involves a diverse array of sample types including laboratory-grown microbial (e.g. bacteria, phytoplankton, protozoa) and zooplankton biomass, water column particulates, sediment trap material, surface microlayer samples, and benthic core samples. For scientists at WHOI such measurements play pivotal roles in studies on phytoplankton and bacterial nutrient dynamics, primary production, water column nutrient cycling, microbial food chain dynamics, water column particulate transformations and fluxes, hydrothermal vent biology and chemistry, petroleum geochemistry, air-sea exchange processes, and benthic-water column interactions. We are requesting a new CHN elemental analyzer that will be shared by a diverse group of WHOI scientists from 4 different departments.
