Remote sensing leads to better understanding of polar regions
28 December 2018
Earth's polar regions feature cold-climate environments characterised by unique landscapes, biota, and processes. The climate in these regions is driven largely by cryospheric processes that are subject to, or have the potential for, fundamental and rapid change in a warming world. Bridging spatial scales and knowledge gaps in these regions requires remote sensing observations.
Myriad Earth observation technologies provide crucial tools to understand and quantify the current state and unprecedented changes occurring in these often remote reaches of our planet. The International Circumpolar Remote Sensing Symposium (ICRSS) series provides a forum for the exchange of current applied research and best practices, presentation of new technology and further innovation, and advancement of international cooperation in circumpolar regions.

The collapsing bluff shows the effects of accelerating erosion, which now exceeds 20 meters per year. Airborne drone remote sensing, which fosters better understanding of permafrost coastal erosion dynamics in northern Alaska, was one among many new technological developments discussed at the 15th ICRSS.
