Narragansett Bay Fixed Station Monitoring Network

University of Rhode Island

Water quality monitoring in estuaries prior to the 1990s was labor-intensive and sporadic, as samples had to be collected and brought back to the laboratory to be analyzed using lengthy procedures with specialized equipment and reagents. During the late 1990s, new innovations in automated water quality sensors made it possible to take measurements directly in […]

7.2 Open Water Buoys

Open water buoys, also referred to as data buoys, provide a stable, floating platform for deploying environmental monitoring instruments in lakes, rivers, reservoirs, estuaries, bays, and coastal or ocean waters. These systems are essential for collecting real-time data in locations that may be difficult or dangerous to access using traditional methods. Buoys can support a […]

7.1 Multi-Parameter Monitoring

Multi-parameter monitoring platforms enable comprehensive environmental data collection by integrating multiple sensors into a single system. These platforms measure a variety of parameters in water, soil, and air. A multi-parameter platform might include, for example, a weather station and water quality sensors for an environmental study on the effect of local weather conditions on a […]

Targeted Monitoring Solutions in the Great Lakes

Great Lakes Research Center

The Great Lakes are in a state of rapid and continuous change resulting from a host of environmental and anthropogenic stressors. Such circumstances require unique, targeted monitoring solutions to meet environmental demands and continuously document these changes. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs such systems, working with research […]
