Acquisition and Upgrade of Instrumentation for Research on Transport and Reactivity of Dissolved and Particulate Organic Materials in Soils, Sediments, and the Atmosphere

0930048 mcknight这笔拨款用于购买一套流动成像系统（FloCAM），以支持对地表水中有害藻类物种大量繁殖的动态调查。该仪器将为科罗拉多大学北极和高山研究所的戴安·麦克奈特和他的同事提供支持。该仪器将支持博尔德溪临界区天文台（CZO）的研究人员，重点研究从大气到地下水位顶部发生的一系列动态过程中溶解和颗粒有机物质的作用。了解通过物理和生物地球化学过程从景观中输送的颗粒和溶解有机质的数量和化学性质，对于理解气候变化如何影响水质和水生生态系统的可持续性至关重要。* * *

0930048McKnightThis grant supports acquisition of a flow-through imaging system (FloCAM) to support investigations of the dynamics of nuisance algal species blooms in surface waters. The instrument will support PI Diane McKnight and colleagues at the Institute for Arctic & Alpine Research at the University of Colorado. The instrument will support researchers involved in the Boulder Creek Critical Zone Observatory (CZO) with a focus on the role of dissolved and particulate organic material in a range of dynamic processes occurring from the atmosphere to the top of the water table. Knowledge of the quantity and chemical nature of particulate and dissolved organic matter transported from the landscape via physical and biogeochemical processes is critical to understanding how climate change might impact water quality and sustainability of aquatic ecosystems. ***
