Eyes in the Sky - Antarctica

Researchers from the University of Kansas, funded by NSF, have successfully tested a radar-equipped Unmanned Aircraft System (UAS) in West Antarctica. This marks the first successful sounding of glacial ice using UAS-based radar. The UAS, weighing 85 pounds, offers a range of 62 miles and is a promising tool for mapping remote and dangerous areas. Previously, such mapping required manned aircraft. The research aims to improve predictive models of ice sheets and sea level rise. The team plans to further miniaturize radar technology and deploy the system in Greenland within two years.

What is the weight of the fully equipped UAS used in Antarctica?

• 85 pounds

• 100 pounds

• 50 pounds

• 120 pounds

Why is the UAS considered a valuable tool for mapping Antarctica?

• It can fly at high altitudes.

• It is cheaper than traditional methods.

• It can map remote and dangerous areas.

• It uses solar power.

What type of areas are scientists particularly interested in mapping with the UAS?

• Desert regions

• Flat ice regions

• Complicated areas with surface scattering

• Urban areas

What is the main goal of the research team at the Center for Remote Sensing of Ice Sheets?

• To build larger UAS

• To develop new radar technologies for military use

• To find cost-effective ways to measure Antarctic ice

• To explore the Arctic region

What kind of data does the UAS provide to the research team?

• Animal migration patterns

• Weather patterns

• Topographical data beneath ice sheets

• Ocean currents

What is one of the future goals for the UAS technology according to the research team?

• To use it for space exploration

• To deploy the system in Greenland

• To increase the weight of the UAS

• To replace all manned aircraft

How will the information gathered by the UAS help in understanding climate change?

• By predicting weather patterns

• By generating accurate estimates of sea level rise

• By measuring air pollution

• By tracking animal populations
