Yellow River near Oak Grove, IN

"Super" gages provide real-time, continuous water-quality information for rivers and streams at selected Ohio, Kentucky, and Indiana U.S. Geological Survey (USGS) streamgages. By combining discrete and continuous data in statistical models, USGS scientists can continuously estimate constituents that are difficult to measure in real-time. For example, in-stream turbidity sensors are often used...

The role of hydrates, competing chemical constituents, and surface composition on CLNO2 formation

Atomic chlorine (Cl•) affects air quality and atmospheric oxidizing capacity. Nitryl chloride (ClNO2) – a common Cl• source–forms when chloride-containing aerosols react with dinitrogen pentoxide (N2O5). A recent study showed that saline lakebed (playa) dust is an inland source of particulate chloride (Cl–) that generates high ClNO2. However...
