Thayer-Snyder and Swanson reported in 2018 that this data set provides landcover and vegetation maps for the Seward Peninsula, Alaska. The Seward Peninsula is located in northwestern Alaska and comprises approximately 15 million acres. A wide diversity of land forms, climate zones, and vegetation are found on the Peninsula. The maps were produced from several projects and data sources including existing maps, Landsat data, and color infrared aerial photography. The data cover the period 1976-06-01 to 1999-09-01.
Map descriptions:
- Seward Peninsula Landsat MSS Classification: The map developed in 1999 covers the entire Seward Peninsula west of an arbitrary line drawn between the Elephant Point to the north, and the Koyukuk River Delta to the south at 50-m resolution. The legend includes six vegetation classes, water, barren, snow and ice, and shadows.
- Seward Peninsula Range Map: A vegetation map of the entire Seward Peninsula (includes the Baldwin Peninsula attached to the northeast corner) initiated with Landsat imagery in 1976 and enhanced using the color infrared aerial photography through 1983 . The map includes 41 vegetation/land cover units. The vegetation survey was designed to provide information for land resource management with special emphasis on reindeer range planning and management.
Project: Arctic-Boreal Vulnerability Experiment
The Arctic-Boreal Vulnerability Experiment (ABoVE) is a NASA Terrestrial Ecology Program field campaign that will take place in Alaska and western Canada between 2016 and 2021. Climate change in the Arctic and Boreal region is unfolding faster than anywhere else on Earth. ABoVE seeks a better understanding of the vulnerability and resilience of ecosystems and society to this changing environment.
