The plan could foster research in smaller areas that are believed to be representative of a broader region or habitat type. 3. Species. The plan could focus on one or a few species throughout the geographic area. 4. Hypotheses. The plan could target research toward a restricted hypothesis, for instance, taking measurements that would support or disprove the Pacific Decadal Oscillation as a cyclic climatic shift. 5. Time. The plan could incorporate intentions to develop research projects in different areas over time.

Because little monitoring has been ongoing for such long periods, continuing past measurements may represent the most effective way of testing for variation at this temporal scale. Second, if two existing measurements show striking correlations, measuring new variables can be an effective way of testing the mechanisms of interaction among complex environmental factors. For instance, if ocean survival of salmon varies with phytoplankton production, then measuring forage fish abundance and demography could provide an intermediate food-web linkage.

Scientific leadership. GEM must have strong scientific leadership. , RIDGE 2000). We examined a number of science plans in an effort to define our expectations of the GEM program plan. These plans are described briefly here. 1. The Long-Term Ecological Research (LTER) funded by the National Science Foundation (NSF) is perhaps the premier long-term scientific monitoring program in the United States. , Everglades, Georgia, Santa Barbara) are of particular relevance to the GEM program because they—like GEM—consider the connection between marine and terrestrial ecosystems.
