Via NEON's overview page: Data will be collected from 106 sites (60 terrestrial, 36 aquatic and 10 aquatic experimental) across the U.S. (including Alaska, Hawaii and Puerto Rico) using instrument measurements and field sampling. NEON will combine site-based data with remotely sensed data and existing continental-scale data sets (e.g. satellite...MORE
This website and database hosts records of fossil pollen, charcoal, and mammal assemblages, as well as plant macrofossils, largely from North America, but also globally, throughout the Pleiocene-Quaternary (and Anthropocene). Also included are chronological controls that allow the use of the records through time from the last 5 million years...MORE
The USGS Gap Analysis Program (GAP) PAD-US is the national inventory of U.S. terrestrial and marine protected areas that are dedicated to the preservation of biological diversity and to other natural, recreation and cultural uses, managed for these purposes through legal or other effective means. Lands in PAD-US are mainly...MORE
