Overview
The RM Young 43502 shield employs a triple-walled intake tube and multiple canopy shades to isolate the sensor from precipitation and solar radiation. A continuous-duty blower draws ambient air through the intake tubes and across the sensor, minimizing radiation errors. Compact shield components reduce radiation absorption and improve aspiration efficiency. Specially selected plastic materials provide high reflectivity, low conductivity, and maximum weatherability.
Design
The versatile DC blower is designed for continuous duty of more than 80,000 hours (9 years) at 25 degrees C (77 degrees F). Brushless electronic commutation is achieved using dependable solid state circuitry.

UNC's industry-standard water quality profiling platforms get upgrade
The University of North Carolina Institute Of Marine Sciences has a history with profiling platforms. UNC engineers and scientists have been building the research floaters for 10 years in a lab run by in Rick Luettich, director of the institute. 
 UNC scientists and engineers developed their own autonomous vertical profilers to take water quality readings throughout the water column. They have three profilers placed in the New and Neuse rivers. The profilers are designed to drop a payload of sensors to an allotted depth at set time intervals. Instruments attached take readings continuously on the way down and up. 
 Data collected by the profilers has been used to study water related issues such as infectious disease and sediment suspension.

When the U.S. Geological Survey began building their climate and permafrost monitoring network in Arctic Alaska in 1998, there wasn't much precedent for how to build the infrastructure for the instruments in the region's unforgiving environment. 
 
That meant the scientists had to learn the particulars on the fly. For example: On the great expanse of flat, barren tundra, a weather station sticks out like a sore thumb to a curious grizzly bear. 
 
"The initial stations were pretty fragile," said Frank Urban, a geologist with the USGS Geosciences and Environmental Change Science Center. "So the bear and those stations--the bear won every single time without any problem.
Read MoreCombating Water Insecurity in Saskatchewan with Real-Time Data
The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. 
 
Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. 
 
Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
