PDF Wetland fire remote sensing research -- The Greater Everglades example [More info]
The U.S. Geological Survey uses remote sensing to improve fire-management databases in the Everglades, gain insights into post-fire land-cover dynamics, and develop spatial and temporal fire-scar data for habitat and hydrologic modeling.
Whales and walrus: tillers of the seafloor [More info]
Report on sea floor marks in the Northeast Bering Sea and Chukchi Sea that were identified as pits and furrows caused by whales and walruses in the process of feeding on bottom crustaceans.
What is an Ocean Bottom Seismometer? [More info]
Description and uses of the Ocean Bottom Seismometer; a self contained data-acquisition system which free falls to the ocean floor and records seismic data generated by airguns and earthquakes.
What Mobilizes Arsenic in Ground Water? [More info]
Research findings and examples of application to real problems--chemical reactions between nitrate, iron, and oxygen can affect the mobility of trace amounts of arsenic.
What on Earth is plate tectonics? [More info]
Discussion and diagrams on plate tectonics and the structure of the Earth for beginners with link to a detailed version: This Dynamic Earth for more information.
Why Study Paleoclimate? [More info]
It's the only way to understand global environmental conditions that were very different from the way they are today.
PDF Wildfire effects on source-water quality--Lessons from Fourmile Canyon fire, Colorado, and implications for drinking-water treatment [More info]
Stream discharge and nitrate concentration increased downstream of the burned area during snowmelt, but these were probably within the treatment capacity of most drinking-water plants, and limited changes were observed in downstream ecosystems.
Wildland fire managers site [More info]
Site with GIS maps of western wildfire areas with some access limited to wildland fire managers.
Wildland fire research [More info]
Thematic descriptions of research to meet the varied needs of the fire management community and to understand the role of fire in the landscape including fire management support, studies of postfire effects, and fire history and ecology.
Woods Hole Coastal and Marine Geology Field Center [More info]
Site with links to projects of the field center of the Woods Hole Coastal Marine Geology Program on underwater areas between shorelines and the deep ocean, off the U.S. East Coast, the Gulf of Mexico, and in parts of the Caribbean and Great Lakes.
Wyoming drought watch [More info]
Gives map of streamflow conditions in Wyoming with access to streamflow data, real-time, daily and historic, plus information on drought analysis and management.
Yakima River Basin [More info]
Description of the studies of the ground water system in the Yakima River Basin and how it interacts with rivers and streams in the basin. Includes links to project status, datasets, maps, project summaries, news releases and bibliographies.
Yellowstone Volcano Observatory (YVO) [More info]
Homepage of the Yellowstone Volcano Observatory with links to information about the observatory at Yellowstone National Park, volcanic history, photo gallery, monitoring data, publications and products, and Frequently Asked Questions (FAQs).
Yosemite Valley geologic story [More info]
Site describes the present understanding of the various geologic processes that contributed to the valley's creation. Links to Yosemite Valley's geologic maps.
