Datasets for all projects.

The long-term data sets of the Arctic LTER include both the monitoring data and data from the whole ecosystem manipulations in tundra, lakes and streams. All of the Arctic LTER data sets are also in the LTER Network Data Catalog (http://portal.lternet.edu) and can be searched by subject (title, abstract and/or keywords), owner, spatial criteria and taxonomic criteria.

Title Abstract
Anaktuvuk River fire scar canopy reflectance spectra from the 2008-2014 growing seasons, North Slope Alaska.

The Anaktuvuk River Fire occurred in 2007 on the North Slope of Alaska. In 2008, three eddy covariance towers were established at sites represent ing unburned tundra, moderately burned tundra, and...
