Sassafras River report card indicates high turbidity, nutrient problems

The Sassafras River Association has been working with people in the Delmarva Peninsula to improve water quality of the Chesapeake Bay tributary, but water quality improvements are still needed, according to the association’s annual report card on river conditions. Nitrogen and phosphorus pollution is a continuing problem in the river due to agricultural operations nearby. There is also high turbidity because of runoff from a number of sources. A series of wetlands maintained by the association and other organizations should improve river conditions in the long run. The Sassafras River’s upper estuary was graded as a ‘C’, the lower estuary as a ‘B’ and the creeks feeding the river were graded as a ‘D.’ The river still is considered an impaired waterway by the U.S.

Testing CO2 Removal Strategies in the Pacific Northwest

The ocean plays a key role in carbon dioxide (CO2) removal and storage, also known as carbon sequestration. However, with increasing emissions, a large amount of CO2 escapes into the atmosphere, worsening climate change and leading to increases in surface temperatures. In order to mitigate some of these impacts, researchers like Ally Savoie at the Pacific Northwest National Laboratory (PNNL) are working hard to identify ways to safely improve the CO2 removal and storage capabilities in the ocean. Savoie started her career at Wright State University , where she worked in Silvia Newell’s lab examining biogeochemical cycling of nutrients in a river system. From there, she decided to pursue a master’s in marine science at the University of Southern Mississippi with Dr.

Smart Buoys Advance Climate Monitoring in Swiss Lakes

Lakes are sentinels of climate change . Globally, they are warming at an unprecedented but uneven rate, and in many places they also face direct human pressure, including from agriculture and recreation. In the Alps, scientists generally agree that climate change is of particular threat to remote lakes , where more pronounced warming threatens fragile ecosystems. Alpine Lakes in a Changing Climate Matteo Tonellotto is part of the team at the Environmental Observatory of the Italian-speaking region of Switzerland (OASI)–a multidisciplinary team of scientists, IT specialists, and chemical laboratory technicians committed to collecting, managing, and integrating high-quality environmental data.

Connecting with Nature in Real-Time at the Abernathy Field Station

Just five miles away from Washington and Jefferson (W&J) College is the 57-acre Abernathy Field Station . Generously donated by the Abernathy family in 2017, the field station has served as an outdoor lab to hundreds of undergraduate students over the years. Many classes use the Abernathy Field Station every week. For example, in BIO 111, students spend 15 weeks conducting their own research at the field station using a combination of sampling, field observations, and real-time environmental data, giving them a look into the world of science and a closer relationship with nature. “We like to start the students in the research process in their first Biology class.
