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 Bill Schmoker, one of 14 teachers nationwide, has been awarded the National Geographic Grosvenor Teacher Fellowship. This article describes his upcoming National Geographic expedition to the Arctic Ocean aboard its research ship 'Explorer'.
PolarTREC teacher Michael League and researchers at the University of Delaware are examining tiny worms that inhabit the frigid sea off Antarctica to learn not only how these organisms adapt to the severe cold, but how they will survive as ocean temperatures increase. This article from the University of Delaware website outlines the research being undertaken to determine whether the
Density currents drive 3D movements within the world’s oceans that dwarf surface currents by volume. Density-driven movements due to temperature/salinity differences keep the world’s oceans well mixed & help to re-distribute heat from tropical areas towards polar areas. Resultant upwelling creates some of the world’s richest ocean ecosystems. Density movements known as turbidity currents are the world’s largest
