The excessive latitudes of the Arctic and Antarctic, including a few mountainous components with glaciers and long-lasting snow, are often referred to as the cryosphere-defined as that part of the planet the place water is perennially or seasonally frozen as sea ice, snow conceal, permafrost, ice sheets, and glaciers.

The committee believes that the promise of an ecosystem-based approach to resource management, which recognizes the changing nature of both the physical environment and species interactions and the fact that many of these changes occur at time scales greater than several years, provides a forceful scientific rationale or conceptual foundation for the GEM program. The other benefit is an explicit recognition that segments of society may have different goals and values concerning marine ecosystems and that those goals and values may conflict.

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. In addition to perhaps providing some ideas to follow as models for GEM, there are opportunities for scientific exchange between scientists working on those LTERs and GEM scientists, and perhaps even the possibility of joint activities, especially where large-scale processes are involved.

The choice among these options requires that existing data be synthesized first. Many of the natural changes in the Gulf of Alaska are thought to cycle at intervals of several decades. 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.
