Questions & Answers
Does the YSI EXO NitraLED measure nitrate as N (NO3-N) or nitrate plus nitrite as N (NO3+NO2-N)?
The sensor reads NO3-N (Nitrate-N) in mg/L. This is due to the fact that the sensor is calibrated in an NO3-N solution and user-performed calibrations are done in that same standard.

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health

It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

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

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.
