Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

South Cascade Glacier, Washington; hydrologic and meteorological data, 1957-67

Historic hydrologic and meteorological data are compiled for South Cascade Glacier, Washington, USA, a site selected by the U.S. Geological Survey for long-term study of the response of a glacier to climate change and its effect on water resources. The data consist of stream discharge and meteorological data, including precipitation, air...

Mass balance, meteorological, and runoff measurements at South Cascade Glacier, Washington, 1992 balance year

Values of winter snow accumulation and summer snow, firn, and ice ablation were measured at South Cascade Glacier, WA, to determine the winter and net balance for the 1992 balance year. The 1992 winter balance, averaged over the glacier, was 1.91 m, and the net balance was -2.01 m. This extremely negative balance continued a trend of negative...

Geometry and flow conditions of subglacial water at South Cascade Glacier, Washington State, USA; an analysis of tracer injections

The comparison between the travel time of the tracers and stream discharge indicated that the single conduit was pressurized in July and partly filled in August and September. To estimate the flow geometry (e.g. path length, flow depth and velocity), the advection-diffusion equation was formulated to express the water velocity as a function of...

Mount St. Helens: Instrumentation and Dome Growth, Nov-Dec 2004

By late October 2004, a whaleback-shaped extrusion of solid lava (called a spine) emerged from Mount St. Helens' crater floor. The 2004–2008 lava dome grew by continuous extrusion of degassed lava spines that had mostly solidified at less than 1 km (0.62 mi) beneath the surface. Scientists deployed monitoring equipment and made visual observations to assess the hazards
