Nutrient Transport, Aquatic Metabolism, and Water Quality in a Changing World
Session ID#: 161769
Session Description:
Metabolism is the pulse of an aquatic ecosystem as reflected by gross primary production, ecosystem respiration, and net ecosystem production. Increased interest in aquatic metabolism reflects its central importance to nutrient transport and water quality and the important roles of key drivers such as climate and land use changes. The central roles of carbon and turbidity are emerging as important factors governing metabolism rates in recent studies. The increasing availability of high-frequency in-situ sensor measurements in rivers, lakes and estuaries as well as new approaches using remote sensing and drones are facilitating improved metabolism and water quality modeling approaches. We welcome investigations that highlight measurements and modeling of nutrient transport, aquatic metabolism and water quality in inland and coastal settings, and encourage investigators to share new insights into the roles of climate change and other anthropogenic factors.
