The Center For Remote Sensing Of Ice Sheets (CReSIS) Investigates Melting Polar Ice

The video discusses the rapid changes in climate and their impact on polar ice in Greenland and Antarctica. It highlights the work of CReSIS, which uses aircraft-based radars to map ice sheets and develop UAVs for efficient research. The video emphasizes the potential of UAVs in scientific contributions and the dynamic changes in glaciers, aiming to prepare communities for rising sea levels.

What is the predicted range of sea level rise by the 21st century due to polar ice changes?

• 20 to 50 meters

• 10 to 30 centimeters

• 50 centimeters to 2 meters

• 5 to 10 meters

What is the primary focus of CReSIS in their research?

• Mapping ice sheets using aircraft-based radars

• Building space stations in Antarctica

• Developing new ice-breaking ships

• Studying marine life in polar regions

Why are surface-based operations around ice sheet margins considered dangerous?

• Due to extreme weather conditions

• Because of high wildlife activity

• Due to lack of proper equipment

• Because of the rough terrain

What is a significant advantage of using UAVs in ice research?

• They can carry more passengers

• They require less fuel compared to traditional aircraft

• They are faster than commercial jets

• They can operate underwater

What is the main goal of the CReSIS team regarding glacier research?

• To stop all glacier movements

• To build new glaciers

• To unlock secrets of glaciers for better preparation against sea level rise

• To melt glaciers faster
