ARCTIC LANDSCAPE EXPLORER (ALEX)

Leads: Anna Irrgang and Tillmann Lübker, Alfred Wegener Institute

ALEX

The Arctic Landscape EXplorer (ALEX) presents land surface change data derived from remote sensing analysis of the permafrost regions throughout the Arctic. Interactive maps provide up-to-date information on land surface changes, hotspots of disturbance, and potential areas of active permafrost thaw and erosion. Using tailored visualizations and story maps as a means to more effectively communicate scientific observations of change, the tool is specifically addressing non-scientific user communities, stakeholders, and rights holders in the Arctic.

Data interpretation

In the landscape change map, flashy colors indicate a substantial change in the landscape. For example, coastal erosion (a trend of a land surface transitioning to a water surface) is depicted in dark blue colors, while coastal accretion (a trend of a water surface transitioning to a land surface) is depicted in bright orange colors. More information about how to interpret the landscape change data can be found on the About page.
