NASA’s Operation IceBridge uses remote sensing techniques to build a picture of parts of our world not accessible or easily observed by humans. Flying 1500 feet above sea and land ice, the science team uses LiDAR, Radar, Infrared imaging, and high resolution digital imagery to collect information about our polar regions year after year. In this classroom project, inspired and
NASA’s Operation IceBridge, the largest airborne survey of Earth’s polar ice, uses remote sensing techniques like LiDAR (light detection and ranging), snow- and ice-penetrating radar, high resolution digital imaging, and infrared cameras to collect information on our changing ice sheets and sea ice. Several times each year a science team and flight crew head out on month-long campaigns in
This lesson incorporates techniques and experimental designs used by researchers during the Southern Ocean Diatoms PolarTREC expedition and during post-expedition laboratory analysis. This guided inquiry lesson provides students the opportunity to explore photosynthesis and primary productivity using techniques to measure chlorophyll levels.
Objectives
SWBAT:
1. Use models to predict chlorophyll levels in the global oceans
2. Identify
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
Have you ever wondered how polar scientists do it? How do they really know if the planet is losing vast quantities of ice anyway? You can use pictures from satellites to monitor the surface from year to year, but the vast majority of ice is hidden from view, buried beneath the surface in some of the most inhospitable and
In mid-April 2012, five teachers from Denmark, Greenland, and the United States, were given the experience of a lifetime. The teachers lived, worked, and flew alongside airborne polar scientists in Greenland, and saw firsthand how remote data are collected on NASA’s Operation IceBridge. In the process, the experience provided the educators with better tools to teach students about science. Read
