This video was taken by John Woods for the International Arctic Buoy Programme Spring Deployment, approximately 100 miles north of Utqiagvik, Alaska. It was filmed at the buoy cluster site where three buoys were deployed on the Arctic sea ice to measure current conditions and take observations.
Melissa Lau spent a month in the tundra ecosystem gathering data using a device called a Greenseeker. This device measures exactly how green a plant is by calculating its NDVI or Normalized Difference Vegetation Index. In this lesson, students will explore light waves, how they interact with plants, and find out how green is green.
