Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges

US Fish and Wildlife Service completed a regional assessment of salt marsh integrity (SMI)  on 15 National Wildlife Refuges/Refuge Complexes in the northeastern US. Developed within a structured decision making (SDM) framework, the SMI assessment provides essential baseline data on salt marsh condition relative to regional management objectives. These data now provide the basis for applying...

Investigations of Sources of Contaminants of Concern in the San Juan River

Metals attached to suspended sediments or dissolved in river water pose a potential health risk to communities that depend on that water for agricultural and domestic uses. Exceedances of Navajo Nation surface water quality standards for metals (especially lead and arsenic) indicate that communities on the Navajo Nation along the San Juan River are exposed to this potential risk. Sources for...

Pacific Northwest Geologic Mapping: Northern Pacific Border, Cascades and Columbia

The Pacific Northwest is an area created by active and complex geological processes. On its path to the Pacific Ocean, the Columbia River slices through a chain of active volcanoes located along the western margin of the U.S. in Washington, Oregon, and northern California. These volcanoes rest above the active Cascadia subduction zone, which is the boundary where the oceanic tectonic plate...

Coral Reef Project: Puerto Rico

To better understand how waves move across coral reefs and cause flooding on tropical shorelines, USGS scientists have installed video cameras and oceanographic instruments off San Juan and Rincón, Puerto Rico. Their work is part of a study funded by USGS after Hurricanes Irma and Maria. The offshore instruments measure wave heights and speeds; the onshore video cameras show where waves break...
