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. ***

0930048 McKnight该基金支持购置一套流动成像系统（FloCAM），以支持对地表沃茨中有害藻类水华动态的调查。 该仪器将支持PI Diane McKnight和科罗拉多大学北极高山研究所的同事。 该仪器将支持参与博尔德溪临界区观测站（CZO）的研究人员，重点关注溶解和颗粒有机物质在从大气到地下水位顶部的一系列动态过程中的作用。 了解通过物理和生物地球化学过程从景观中迁移的颗粒和溶解有机物的数量和化学性质，对于了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。 ***
