NASA | IceBridge 2010 with Lora Koenig

NASA is monitoring sea ice and ice sheets using aircraft due to the loss of the IceSat satellite. The aircraft provide enhanced capabilities, allowing for more detailed measurements. Current findings show Arctic sea ice is slightly below average in extent but thinner than usual. The Arctic is a critical indicator of climate change, affecting global sea levels. NASA's aircraft are equipped with LIDAR and radar instruments to study ice dynamics. More information can be found on NASA's website.

What changes have been observed in the outlet glaciers of the Greenland ice sheet over the past two decades?

What types of instruments are used on NASA's aircraft for monitoring ice, and what do they measure?
