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.
Students will examine sunspots and track them at different latitudes on the Sun.
This activity is adapted from the Tracking Sunspots activity on NASA’s Solar and Heliocentric Observatory (SOHO) website (2009): https://soho.nascom.nasa.gov/classroom/for_students.html.
Objectives:
Students begin to familiarize themselves with solar activity by tracking sunspots at different latitudes on the Sun.
This activity is designed to get students thinking about
Understanding Physical and Chemical Parameters of Ocean Water Using CTD Profiles
Overview
A focus of the PolarTREC Southern Ocean Diatoms expedition was to collect water samples and physical profile data using oceanographic technology. Oceanographers rely on the real-time data transferred from the water column to the ship-based computers using a CTD sensor. The CTD measures conductivity (salinity), temperature and depth
