ABoVE

Thirty+ Year Timeseries of Arctic Land Cover

Land Cover Classes.

Land cover (10-class product) for the year 2014 for ABoVE tile BH03V04. The pixel resolution is 30 m and a tile is 180 x 180 km.

Research from NASA's ABoVE project provides annual land cover classifications from 1984 to 2014 for Alaska and the Canadian Arctic.

Two new datasets provide soil active layer thaw depth and end-of-season snow depth at sites near Fairbanks, Alaska.

Changing Availability of Subsistence Resources in Alaska

Lake grass vegetation at Tok.

This photo from June 2016 shows the "extreme" growth of lake grass in a lake near the Tok Community, Alaska.

ABoVE researchers worked with rural communities to document environmental changes that affect access to subsistence resources.

Sub-Meter Scale Vegetation Maps for Toolik Lake, Alaska

Vegetation communities.

Vegetation communities for the Toolik footprint shown at 1:25,000 scale.

Plant communities near Toolik Lake research station in Alaska were classified at 20 cm resolution based on airborne imagery and lidar surveys.

Spectral Reflectance of Tundra Plants

Common Garden Ecotype site.

A plot at a common garden ecotype site near Eagle Creek, Alaska. Common garden sites were established with different populations of the tussock-forming sedge taken from different latitudes in Alaska.

Researchers with the Arctic-Boreal Vulnerability Experiment (ABoVE) measured plot-level and species-specific full-spectrum reflectance data for tundra plants.
