NASA's ICESat-2 Looks Beyond the Icy Poles

The video tutorial covers the mapping of underwater topography using reflective limestone deposits, the role of vegetation like Mopani and Acacia in carbon storage, and the monitoring of glaciers using I Sat 2. It highlights the importance of understanding carbon uptake in neglected ecosystems and the impact of climate change on glacier dynamics, including thinning and slowing down.

What causes the strong signal returns from beneath the water surface in the mapped area?

• Reflective limestone deposits

• High water temperature

• The shallow depth of the water

• The presence of dense vegetation

Which type of vegetation is dominant in the profile discussed in the video?

• Cactus plants

• Mangrove trees

• Shrub Mopani

• Pine trees

Why is it important to understand carbon storage in savannah and woodland ecosystems?

• They have the highest biodiversity

• They are rapidly expanding

• They are often neglected in global carbon accounting

• They are the largest carbon sinks

What unique capability does I sat too have in studying glaciers?

• It can measure the temperature of glaciers

• It can see into the valleys of steep topography

• It can predict future glacier movements

• It can detect the color of glacier ice

How are glaciers in High Mountain Asia responding to climate change?

• They are melting and moving faster

• They are remaining stable

• They are thinning and slowing down

• They are thickening and speeding up
