Long-Term Ag Change Impacts Stream Water Quality

In the early 1990s, Acton Lake in southwestern Ohio had a muddy problem. Large amounts of sediment from nearby farms were entering the lake’s watershed. These sediments traveled through streams draining the landscape and were filling up the lake. So the USDA gave local farmers incentives to change some of their farming practices. One of

NASA Flights Map Summer Melt of Greenland Ice

Operation IceBridge is flying in Greenland to measure how much ice has melted during the summer. The flights, which began on Aug. 25, 2017, and will go on until Sept. 21, 2017, repeat paths flown this spring and aim to monitor seasonal changes in the elevation of the ice sheet. “We started to mount these

Historical Records May Underestimate Sea-Level Rise

A new study using NASA satellite data finds that tide gauges—the longest and highest-quality records of historical ocean water levels—may have underestimated the amount of global average sea-level rise that occurred during the 20th century. A research team led by Philip Thompson, associate director of the University of Hawaii Sea Level Center in the School
