A continuous water-quality gage (known as a super or sentry gage) uses in-stream instruments to measure streamflow, water-quality characteristics, nitrate, and phosphate many times a day and through- out the year. Traditional, intermittent water samples can miss changes in water quality that happen at night, during storms, and when it is not practical or affordable for a sample team to operate. A statistical model can be used to combine continuous and intermittent water- sample data at super gages so that constituent concentrations and loads (such as pounds per day) can be continuously computed. Tim Lathrop will be presenting his experience with USGS super gage monitoring around the Midwest.

Gases trapping solar heat in the atmosphere are called green house gases. Methane (CH4) is the second most prevalent greenhouse gas emitted in the United States from human activities (the first one being carbon dioxide). In 2014, methane accounted for about 11 percent of all U.S. greenhouse gas emissions from human activities. Although methane is much more potent green house gas than carbon dioxide (25 times greater impact on climate change than CO2 over 100 years), its longevity in the atmosphere is only about 12 years.
Methane is emitted by natural sources such as wetlands, lakes and the oceans, as well as human activities such as leakage from natural gas systems, landfills and the raising of livestock.
Water body methane emissions play an important role in the global methane emission budget, but there are large uncertainities in methane fluxes estimates from natural and anthropogenic systems. Researchers in Ohio work on evaluating methane fluxes from both of these sources.
- Prof. Bohrer projects funded by NSF and Ohio WRC investigate methane fluxes from natural and anthropogenic sources in shale gas development areas.
- Prof. Buffam and Hamilton project funded by Ohio WRC 104(b) program evaluate how are Ohio reservoirs methane emissions influenced by nutrient enrichement.
The Ohio Water Resources Center is supporting and helping to administer Project WET (Water Education for Teachers) together with the Ohio EPA, ODNR and WMAO. Project WET’s mission is to reach children, parents, teachers and community members of the world with water education that promotes awareness of water and empowers community action to solve complex water issues. Since its creation in 1984, Project WET has achieved its mission by:
- Publishing water educational materials
- Providing training workshops for teachers
- Organizing community water events
- Creating network of water resource professionals
