It is no secret that in today's world, most scientists do not stick exclusively to science–they must be educators, communicators, and advocates. 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.Read More
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.Read More
The United States' national parks are visited by millions of people each year, providing opportunities to experience the local beauty of the U.S. A core mission of the National Park Service (NPS) is to protect and preserve these unique areas since they are not totally free of pollution and the influence of climate change.
As such, national parks are the site of many environmental monitoring programs designed to assess the effects of global stressors like climate change and pollution on park resources. Acadia National Park's water and air monitoring programs are examples of this, providing a long-term data history documenting changes in air and water quality over the past four decades.Read More
