Dataset Description

This dataset contains a list of keywords and keyterms used in U.S. LTER documents and datasets. It was jointly created by the Information Management Committee of the U.S. LTER.
Publications using data from the Virginia Coast Reserve Long-Term Ecological Research Project should cite the dataset and its originators. Additionally, they should include the following paragraph:
Some data used in this publication was provided by the Virginia Coast Reserve LTER project, which was supported by National Science Foundation grants BSR-8702333-06, DEB-9211772, DEB-9411974, DEB-0080381 and DEB-0621014.

General Methods

Lists of words and terms, along with the identity of the source documents, number of sites where a word was used and total number of uses were tallied. The lists were combined and tallied using the SPSS program listed below:
