The Extech Sound Level Meter has a background sound absorber mode for machine noise measurements that filters ambient noise. It can easily interface with a PC to capture data directly via the optional Windows compatible software. Its high-accuracy specification allows the unit to meet type 2 standards (ANSI S1.4-1983, IEC 60651, EN 60651). An electret condenser microphone provides high-accuracy measurements. Live readings can be read clearly on the large display with backlighting and analog bargraph. The meter has 6 auto or manual ranges from 30 to 130dB.

Climate Change Asymmetry Transforming Food Webs
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.

New Technologies Reducing Uncertainty in Estimation of River Flow
Some of the most interesting data in the world of river and stream monitoring come at times when it's practically impossible to capture—during extreme weather events, for example. Timing alone makes capturing unusual events a challenge, and these kinds of issues have prompted researchers to use classic monitoring data along with new technologies to develop and improve hydraulic modeling for estimating river flows. Steven Lyon , a Conservation Scientist with The Nature Conservancy, Professor at Stockholm University and Associate Professor at The Ohio State University, spoke with EM about the research .

Cornell University Biological Field Station at Shackelton Point: Monitoring New York’s Largest Interior Lake for Sixty Years
Lars Rudstam, Professor of Aquatic Science at Cornell and Director of the Cornell University Biological Field Station at Shackelton Point, says that he has long held an interest in lakes in general, so naturally the Great Lakes, the largest freshwater lake system in the world, have held a fascination for him for many years. He also works on Oneida Lake, the largest lake wholly inside New York. Oneida Lake waters, traveling from the Lake to the Oneida River, then to the Oswego River, ultimately flow into Lake Ontario. “In addition to lakes in general and the Great Lakes, I have been especially interested in the impressive data series that has been collected for Oneida Lake,” Rudstam notes.
