|606150||6150 ROX optical dissolved oxygen sensor with self-cleaning wiper|| |
Note: All optical DO membranes are now manufactured from anti-fouling copper alloy; these membranes directly replace black plastic membranes. Anti-fouling membranes can be used on existing ROX probes with no detrimental effects on data. The copper-alloy YSI 6155 optical DO membrane may arrive with surface patina and/or discoloration. This will not affect membrane performance.
- (1) YSI 6155 optical DO membrane
- (3) Installation screws
- (1) Hex wrench
- (1) Instruction sheet with calibration coefficients

A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch.
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.”
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.Read More
Utah’s Canyonlands Research Center: A Great Study Location for Climate Effects on Ecosystem Processes, Community Dynamics and More
Canyonlands Research Center (CRC) is situated at The Nature Conservancy’s Dugout Ranch , over 5,200 private acres of research study area. One of CRC’s primary roles is to facilitate research and monitoring work of university and federal researchers. CRC is located adjacent to Canyonlands National Park , which extends over more than 337,000 acres of public land. CRC also partners with many organizations, including the Bureau of Land Management, USFS, NPS, USGS, Utah State University, and the Utah Division of Wildlife Resources to identify the most pressing research needs in this region.Read More
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 More
