The NexSens TS210 Thermistor String provides high accuracy temperature data for profiling in lakes, streams, and coastal waters. It features an integral titanium thermistor secured and epoxied in a protective housing for underwater deployments. A marine-grade cable with braided Kevlar core help ensure reliability in extreme environments.
Each sensor is accurate to +/-0.075 C for high-precision measurements. The exposed titanium thermistor makes direct contact with water, allowing readings to stabilize within 60 seconds. Temperature data is transmitted on a RS-485 Modbus RTU string bus for integration with data loggers and SCADA systems. The string is powered by 4-28 VDC for operation on a 12 or 24 VDC power supply.
TS210 strings are available standard with 1m spacing or at custom intervals to meet project requirements. Cable lengths are available up to 1,219 meters (4,000 feet) with a maximum 250 nodes. Strings terminate in a NexSens UW plug and receptacle connector, allowing additional sections or sensors to be added as required. Optional accessories include a bottom pressure sensor, cable clamps, stainless steel mooring line, and communication adapters.

Watchful Eyes on One of Maine's Crown Jewels: Jordan Pond
Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it. 
 
 EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project. 
 
 Friends of Acadia is a nonprofit organization that supports different projects in the park.

Recent research from a University of Guelph (U of G) team reveals that warmer temperatures caused by climate change are forcing species to alter their behavior, causing food webs in Ontario lakes to transform. As temperatures warm, larger species hunt new prey in deeper waters, changing the ways nutrients and energy flow in lakes and triggering a “rewiring” of food webs. 
 
 Dr. Timothy Bartley , study lead author and a post-doctoral researcher in the U of G's Department of Integrative Biology , spoke to EM about the work . 
 
 “I got started on this when I first began graduate school and joined an ongoing project, which was a collaboration with the Ontario Ministry of Natural Resources and Forestry ,” explains Dr. Bartley.
Read MoreLake Of Egypt Temperature Buoy Profiles Effects Of Power Plant Discharge
Illinois’ Lake of Egypt provides a lot for the nearly 8,000 people living around it. Drinking water is first on the list, followed by boating and fishing opportunities. But its waters also help to provide something they don’t have to be on the lake to enjoy: electricity. 
 
The lake’s water is the main coolant used by a coal-fired power plant sitting on its banks. It’s operated by the Southern Illinois Power Cooperative, where employees have, for years, managed the temperature of water discharged back into Lake of Egypt using calculations. The method relied on temperature readings taken at the discharge point, which were then used to estimate conditions further out into the water body.
