The YSI 1004 ammonium ISE sensor employs a silver/silver chloride (Ag/AgCl) wire electrode in a custom filling solution. Nonactin membrane separates the internal solution from the sample medium and this membrane selectively interacts with ammonium ions.

When the probe is immersed in water, a potential is established across the membrane that depends on the relative amounts of ammonium in the sample and the internal filling solution. This potential is read relative to the reference electrode of the instrument pH probe. As for all ISEs, there is a linear relationship between the logarithm of the ammonium activity (or concentration in dilute solution) and the observed voltage. The Nernst equation describes this relationship.

Monitoring for Runup Signals to Reduce Sneaker Wave Risk

Around the world, the occasional phenomenon known as sneaker waves poses a threat to beachgoers. Unusually large sneaker waves in 2016 and 2018 prompted Oregon State University (OSU) researchers to investigate these mysterious events. The research revealed the presence of runup signals that can provide earlier warnings to officials, reducing risk from these dangerous events. Dr. Tuba Ozkan-Haller of OSU spoke to EM about the research . “Sneaker waves occur in the Pacific Northwest, but they're also a worldwide phenomenon,” explains Dr. Ozkan-Haller. “Certain kinds of coastlines appear to be more well-suited to the occurrence of these waves. There are some characteristics that we know play into it, but there's still a lot of unknowns too.

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.

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.
