                  -              Overview           

A new Landsat project is adding more images of polar regions so that rapid changes happening there can be mapped in more detail.

Landsat has documented changes all over the world for over 50 years. Changes in polar regions are happening especially rapidly. But it’s dark in polar regions much of the time. Therefore, a new acquisition scheme is adding more imagery of these dark, polar regions so these changes can be studied in more detail, even in polar twilight. In this episode of Eyes on Earth, we learn about this project, called the Landsat Extended Acquisition of the Poles (LEAP).

The Arctic is changing at a more rapid rate than the rest of the planet. Some of the most significant changes are tied to the thawing of near-surface permafrost, the layers of frozen soil containing vast stocks of stored carbon.
