Quick look: Population growth and changes in land use have the potential to affect water quality and quantity in the upper Gunnison River Basin. In 1995, the U.S. Geological Survey (USGS), in cooperation with the Bureau of Land Management, City of Gunnison, Colorado River Water Conservation District, Crested Butte South Metropolitan District, Gunnison County, Hinsdale County, Mount Crested Butte Water and San Comparison of 2008-2009 water years and historical water-quality data, upper Gunnison River Basin, Colorado(Released: Fri, 12 Oct 2012 00:00 -0500)
Quick look: Carbon nanotubes (CNTs) are hydrophobic in nature and thus tend to accumulate in sediments if released into aquatic environments. As part of our overall effort to examine the toxicity of carbon-based nanomaterials to sediment-dwelling invertebrates, we have evaluated the toxicity of different types of CNTs in 14-d water-only exposures to an amphipod (Hyalella azteca ), a midge (Chironomus Toxicity of carbon nanotubes to freshwater aquatic invertebrates(Released: Thu, 11 Oct 2012 00:00 -0500)
Quick look: Areal cover and occupancy of woody riparian species near 456 streamgages in the western United States were obtained from site visits during the growing seasons of 1996-2002. We made concomitant estimates of grazing intensity, channel stabilization and incision, gradient, sediment particle size, and nearby planting of Russian olive. The purpose of this publication is to describe the data set and ma Woody riparian vegetation near selected streamgages in the western United States(Released: Thu, 11 Oct 2012 00:00 -0500)

Mount St. Helens’ Runaway Glacier: A time-lapse video of Crater Glacier’s response to lava dome growth
Quick look:
From 2005 to 2010, the U.S. Geological Survey-Cascades Volcano Observatory operated a remote camera on the northwest flank of Mount St. Helens. Looking into the crater, the camera captured hourly photographs of volcanic dome growth during the 2004-2008 eruption. The station also captured the ad...
Latest Audio or Podcast ShakeOut Drill: Preparing for Earthquakes
Quick look:
The next Great ShakeOut earthquake drill will be held on October 18, 2012. During the drill, participants will "drop, cover, and hold on" to practice how to protect themselves during an earthquake.
To give us some details on ShakeOut, we are joined by two guests. First is Mike Blanpied,...
