Culturing Change: Exploring Climate Science with Algae Experiments

Biology experts John Melville, PhD, and Sara Tallarovic, PhD, along with guest Matthew Huber, MS, Chief Scientist at Algae Research and Supply, use algae cultures in experiments that explore primary productivity. Learn how to use the Go Direct® Optical Dissolved Oxygen Probe with algae cultures to measure dissolved oxygen levels in water and determine the effect of light on the rate of photosynthesis. This video also covers how to connect these measurements to carbon fixation through pH levels and explore the ocean’s role in reducing levels of atmospheric carbon.
