NASA | Keeping a Close Eye on Jakobshavn

Operation Icebridge revisits Jakobshavn Glacier, a key research site due to its rapid movement and iceberg production. The mission aims to gather data on glacier changes and their impact on sea level rise. The study focuses on the upstream catchment area and calving front, using advanced imagery and laser elevation data. Future missions will continue to build a comprehensive record of polar changes, bridging the gap between NASA's Icesat missions.

What year did Operation Icebridge return to Jakobshavn Glacier for its fifth consecutive mission?

• 2010

• 2013

• 2016

• 2015

Why is Jakobshavn Glacier a focus for researchers?

• It is the largest glacier in the world.

• It is located in Antarctica.

• It is the fastest moving glacier in Greenland.

• It has the most stable ice front.

What is the primary objective of the Icebridge mission over Jakobshavn Glacier?

• To observe the wildlife in the area.

• To study the upstream catchment area.

• To measure the temperature of the ice.

• To study the calving front exclusively.

What is the purpose of creating a continuous record of changes in polar regions?

• To improve tourism in the area.

• To stop the production of icebergs.

• To bridge the gap between NASA's Icesat missions.

• To increase the speed of glacier movement.

What is the significance of the calving front in the Icebridge mission?

• It is not observed during the mission.

• It provides a highlight with detailed imagery.

• It is the least important part of the mission.

• It is only studied in the summer.
