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 event by Melissa Barker explains the research being done at Toolik Field Station, Alaska on nutrient transport in arctic watersheds. She is joined by team member Dr. Sarah Godsey.
