TROY, N.Y. As the planet heats up, are lakes releasing more carbon dioxide into the atmosphere? With a prestigious National Science Foundation Faculty Early Career Development (CAREER) grant, researcher Kevin Rose will examine large-scale patterns in concentrations of carbon dioxide (CO2) and dissolved oxygen to answer the question.
Dissolved oxygen levels in freshwater lakes are declining, indicating a potential increase in CO2 emissions. Theoretically, freshwater life links CO2 and dissolved oxygen to one another. Algae and plants consume CO2 and produce dissolved oxygen, while animals like zooplankton, fish, and bacteria consume dissolved oxygen and produce CO2. But for many reasons, the relationship between the two measurements has not been rigorously tested.
Lincoln, Neb. Scientists have long known that all living things require specific amounts of elements such as carbon, nitrogen, and phosphorous to survive and thrive it’s why we fertilize our yards and crops, for example. But the increasing frequency of phenomena such as harmful algal blooms, nitrate-contaminated water, and “dead zones” in oceans [.]
