Case Studies
Monitoring An Active Thermocline, Rapid Changes
Beginning in the 1990s, researchers have collected samples manually every few weeks on trips to Lake Champlain to gather data on its dynamics. But the metrics the team has collected are spotty, considering the faster-paced changes fueled by a changing climate.To help fill in those holes, researchers from the State University of New York (SUNY)—Plattsburgh deployed a cellular data buoy in the lake near Valcour Island. The buoy is providing previously unavailable data in real-time, helping research and education at the university, improving National Weather Service forecasts, and keeping local fishermen a little safer. Challenge: Monitoring the entire thermocline in real-time Previous attempts to monitor Lake Champlain’s thermocline only reached from six meters beneath the surface to the sediments—but the available data reveal that the lake experiences extreme fluctuations at times due to an active seiche and wind.
Lake Nipissing Algae Events
Despite Lake Nipissing’s popularity as a destination for tourists and fishermen in Ontario, Canada, relatively little is known about nutrient availability for algae that sometimes blooms there. Luckily, several investigators at the University of Saskatchewan and Nipissing University are working to fill the gap in understanding.Key to answering their questions is learning more about the lake’s stratification, or how its water column differentiates based on changes in temperature. These differences play an important role in how the lake mixes -- during long periods of stability, bottom waters can become anoxic and sedimentary phosphorus can become mobile and available to Lake Nipissing algae communities.To record the shifts that occur, researchers needed reliable equipment to monitor temperatures in a profile, collect data on water quality and also gauge weather dynamics at two sites in the lake. NexSens Technology provided gear for the project, including data buoys, multi-parameter sondes, temperature strings and weather stations. Two buoys are better than one
Managing Plant Discharge Temperatures
The Southern Illinois Power Cooperative operates a power plant near Lake of Egypt around the clock to produce energy for its customers. All the activity can stress the plant’s infrastructure, so key to continuing its operations is minimizing that stress as much as possible.One of the main issues that plant managers encounter in overseeing operations is keeping equipment from overheating. They routinely pump in water from the lake to cool generators and ensure reliable power generation in the long term. Through being used as a cooling agent, the water is heated up considerably, and then must be condensed and cooled before it can be discharged back into the reservoir.From that point in the process, plant managers monitor conditions in the reservoir to make sure that water plant discharge is cool enough to not impact water temperatures. Their concern is that overheated water could upset the ecosystem balance and hurt aquatic life and they work to put the water back in close to the temperature of the surrounding water.
