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.
This one hour live event is hosted by PolarTREC teacher Lisa Seff and her team studying the oceanographic conditions of bowhead whale habitat. The team is stationed in Barrow, Alaska.
