Core datasets collected by NTL represent a suit of long-term data sets across the 5 core LTER areas of primary production, population dynamics and trophic structure, organic matter accumulation and use, inputs and movements of nutrients through the ecosystem, and patterns and frequency of disturbances.
These datasets are continually updated. The EDI links below may alert you that a new update is available.
This is an accordion element with a series of buttons that open and close related content panels.
HOW TO CITE DATA IN PUBLICATIONS
Our data is licensed as CC-BY, which allows use (i.e., scientific and commercial) of the data but with proper attribution (citation). All EDI datasets provide formal data citations on the package summary page. E.g.
