Thin Ice: Year-Long Monitoring in Missouri Reservoirs

The value of multi-lake studies is well understood by international organizations like the Global Lake Ecological Observatory Network (GLEON) and the scientists who work tirelessly to provide data to the larger network. Rebecca North, an associate professor at the University of Missouri-Columbia , is one of many researchers involved in multi-lake research initiatives and conducting research locally in her home state. Having been born and raised on the shore of Lake Ontario, North grew up in a community that revolved around water. She also saw firsthand one of the worst water quality bodies of the world, the Bay of Quinte, decline throughout her lifetime.

Duality of Science: The Importance of Science Communication for Promoting Change

The looming threats facing the planet's climate and the growing distrust in science by the public have forced scientists to expand and improve their capacity for science communication to the world.  From repeatedly testifying before the U.S. Congress to winning an Emmy as the Chief Scientific Advisor for an award-winning nature documentary, marine ecologist James W. Porter has been thrust into the public eye.

Thin Ice: Monitoring Winter Lake Dynamics at Mohonk Lake

Historically, water quality monitoring during the winter has been difficult and often avoided altogether—however, monitoring throughout the year can highlight the influence of various environmental stressors and track the changes systems undergo during the winter. In particular, long-term monitoring efforts in systems like Mohonk Lake can underline the effects of climate change and acid rain. David Richardson, a professor of biology at the  State University of New York (SUNY) at New Paltz , spends his time outside of the classroom monitoring the nearby watersheds. After getting his engineering undergraduate degree, Richardson realized he wasn't interested in the typical job offerings and applied to an ecological science graduate program at the University of Maryland.
