Water Current Monitoring

Nearshore fisheries, climate researchers, search and rescue crews and even the general population can benefit from accumulated water current data. Currents help shape the climate in some regions and monitoring in real-time can detect changes and reveal patterns.

NexSens offers complete current profiling systems with telemetric data transfer from either a mounted or floating platform. Acoustic Doppler current profilers employ the principle of Doppler shift by calculating the difference in time between the sent and the received signal. A NexSens data logger automatically pushes water current data to WQData LIVE datacenter.

Tracking Flow For Hydropower

The Northern Indiana Public Service Company (NIPSCO) is a large energy provider in the state of Indiana. It provides power to more than a million customers through distributing energy derived from natural gas and hydropower dams. As part of achieving its mission to provide reliable energy to its customers, officials at the company have to be aware of changing flow rates near its hydropower assets. The real-time calculations are necessary for keeping plant managers up to speed on factors that could influence hydropower output.

Michigan’s Muskegon Lake Sentinel

In 1985, Muskegon Lake was designated an Area of Concern by the U.S. EPA because of water quality and habitat problems associated with pollution discharged into its waters. The water body, which sits between the eastern shore of Lake Michigan and the Muskegon River, has been the site of remediation work ever since. In line with work to bring the lake back from its status as an Area of Concern, scientists at Grand Valley State University launched a massive data-collection system in spring 2011. Comprised of two buoys and dozens of sensors to measure the lake’s health, the system is cluing researchers in to Muskegon Lake’s dynamics like never before.

Great Lakes Buoy Networks

The Great Lakes region is a dynamic ecosystem that supports millions of people, plants and animals. Key to maintaining its vitality is making sure the waterways that sit at its base remain clean and healthy. To do that, scientists and water managers need steady, reliable data. They often get this information from buoy networks. There are many different Great Lakes buoy networks out there, which are largely supported by government agencies and universities. Maintaining these networks, including servicing old buoys or launching new ones, is a big and important job.
