Palmyra Atoll in the tropical Pacific is a "living laboratory" for multi-disciplinary research on coral reef ecosystems, insular terrestrial ecosystems, climate change, and the lingering effects of Cold War nuclear testing.
Article from American Scientist on study of the San Francisco Bay estuary as a component of the global climate system showing that natural fluctuations might be mistaken for anthropogenic trends affecting waterflow and salinity.
This report serves as an environmental review and framework for developing USGS programs in the south Florida ecosystem, especially the Everglades and its watershed, and stresses the critical role of water in natural and human environment.
