NASA | OPERACIÓN ICEBRIDGE: Explorando cambios en el hielo de Groenlandia

A NASA scientist discusses a mission in Greenland and Antarctica to study ice sheets using a retrofitted P3B aircraft equipped with lasers and radars. The mission aims to measure ice thickness and structure, and analyze geological composition. Observations reveal rapid ice melting, highlighting environmental concerns.

What is the primary goal of the IceBridge mission?

• To study the evolution of ice sheets

• To explore new planets

• To measure ocean temperatures

• To develop new aircraft technology

Which aircraft is used in the IceBridge mission?

• P3B military aircraft

• Boeing 747

• Cessna 172

• Airbus A320

How do lasers on the P3B aircraft help in measuring ice sheets?

• By sending light pulses that bounce off the ice surface

• By capturing images of the ice

• By emitting sound waves

• By drilling into the ice

What additional information do radars provide compared to lasers?

• Speed of the ice flow

• Thickness and structure of the ice

• Color of the ice

• Temperature of the ice

Why is the study of the Russell Glacier important?

• It is a tourist attraction

• It is located in Antarctica

• It is melting rapidly, indicating climate change

• It is the largest glacier in the world
