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
Free community viewing of Taking Earth's Temperature -Delving Into Earth's Past followed by Q & A w/contributor Dr. Jason Briner. Organized by PolarTREC teacher, Tina Ciarametaro in her home community after her expedition to Greenland. Learn more here about the documentary Taking Earth's Temperature.
News release letter for Tina Ciarametaro's expedition to Greenland to study shrinking arctic icecaps. The release explains the upcoming expedition, PolarTREC's goals/objectives and how to follow the expedition.
The attached PowerPoint is an introduction to thermal stratification and turnover in lakes, and interpretation of temperature profile data. The stand-alone presentation can be used to complement a lesson in Earth Science.
To learn about the effects of air pollution on Sea Ice. This can be a library/computer lab-based activity.
Procedure
Teacher:
1. Mix up a 3.5% solution of NaCl. Make enough "sea-ice" cubes for each pair of students
2. Make another class set of ice cubes with tap water. Leave the ice in the freezer until after the
To compare the conductivity of freshwater and seawater. This is a lab activity, and students should be taught appropriate safety measures, including eye protection and safety while using electricity.
Procedure
1. Use the table in attached PDF to record your data.
2. Put 100 mL of 3.5% NaCl solution into a 250 mL beaker.
3. Attach 2
