U.S. Geological Survey continuous monitoring workshop—Workshop summary report U.S. Geological Survey continuous monitoring workshop—Workshop summary report
Executive Summary The collection of high-frequency (in other words, “continuous”) water data has been made easier over the years because of advances in technologies to measure, transmit, store, and query large, temporally dense datasets. Commercially available, in-situ sensors and data-collection platforms—together with new techniques for data analysis—provide an opportunity to monitor...

A surrogate regression approach for computing continuous loads for the tributary nutrient and sediment monitoring program on the Great Lakes A surrogate regression approach for computing continuous loads for the tributary nutrient and sediment monitoring program on the Great Lakes
Water quality (WQ) in many Great Lake tributaries has been degraded (increased nutrient and sediment concentrations) due to changes in their watersheds, resulting in downstream eutrophication. As part of the Great Lakes Water Quality Agreement, specific goals were established for loading of specific constituents (e.g., phosphorus). In 2010, the Great Lakes Restoration Initiative was...

Emerging tools for continuous nutrient monitoring networks: Sensors advancing science and water resources protection Emerging tools for continuous nutrient monitoring networks: Sensors advancing science and water resources protection
Sensors and enabling technologies are becoming increasingly important tools for water quality monitoring and associated water resource management decisions. In particular, nutrient sensors are of interest because of the well-known adverse effects of nutrient enrichment on coastal hypoxia, harmful algal blooms, and impacts to human health. Accurate and timely information on nutrient

Organic contaminants in Great Lakes tributaries: Prevalence and potential aquatic toxicity Organic contaminants in Great Lakes tributaries: Prevalence and potential aquatic toxicity
Organic compounds used in agriculture, industry, and households make their way into surface waters through runoff, leaking septic-conveyance systems, regulated and unregulated discharges, and combined sewer overflows, among other sources. Concentrations of these organic waste compounds (OWCs) in some Great Lakes tributaries indicate a high potential for adverse impacts on aquatic...

Community for Data Integration 2013 Annual Report Community for Data Integration 2013 Annual Report
The U.S. Geological Survey (USGS) conducts earth science to help address complex issues affecting society and the environment. In 2006, the USGS held the first Scientific Information Management Workshop to bring together staff from across the organization to discuss the data and information management issues affecting the integration and delivery of earth science research and investigate...

Temporal changes in aquatic-invertebrate and fish assemblages in streams of the north-central and northeastern U.S. Temporal changes in aquatic-invertebrate and fish assemblages in streams of the north-central and northeastern U.S.
Many management agencies seek to evaluate temporal changes in aquatic assemblages at monitoring sites, but few have sites with ecological time series that are long enough for this purpose. Trends in aquatic-invertebrate and fish assemblage composition were assessed at 27 long-term monitoring sites in the north-central and northeastern United States. Temporal changes were identified using...
