Melt Ponds, Summer Ice, and More: Space Laser Measures Changing Earth Since 2003, Arctic sea ice has lost about a third of its volume. On the opposite side of the world, at the other pole, new glacial lakes were discovered deep below the surface of Antarctic ice. And at latitudes in between, changi
Those are just a few of the 100-plus new discoveries made with precise height data from the 12 trillion laser measurements collected fromSince its launch in September 2018, ICESat-2 has gathered data and inspired research on our changing Earth – ranging from ice to tropical beaches and boreal forests to urban areas. Before launch,about what they hoped it would help us understand.

“So when we repeat orbits to measure how things change over time, we can get a better sense of things like the grounding zone of ice shelves, where the ice meets the ocean. We can better measure where those are, and also see the impact of tides on the floating ice.”
