Long-Term Measurements at the Arctic LTER Site
Ecologists are collecting a number of long-term datasets at the widespread sites of the National Science Foundation’s (NSF) Long-Term Ecological Research (LTER) Program. The goals of the LTER are to carry out basic ecological research on questions best studied over years and decades and over large areas. In this chapter, we illustrate the decisions taken at one site, the Arctic LTER, about the questions appropriate for long-term study, and we show the multitude of ways in which long-term datasets have contributed to our understanding of the Arctic.
