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.
PolarTREC Teacher Chantelle Rose conducted this PolarConnect event while aboard the USCGC Healy on 7 December 2011. There is a short gap in the audio recording of the presentation. Only one question about capture nets is missing from recording.
