Tsunami Research Keeping People Safe

Kara Capelli — Wed, 18 Nov 2009 00:00:00 EST

When a 40 foot tsunami wave hit the shores of American Samoa on Sept. 29, 2009 thousands of locals made it safely to higher ground, thanks to education efforts and research.

Too Much of a Good Thing: Increasing Nitrogen Deposition in Lakes

Marisa Lubeck — Thu, 12 Nov 2009 00:00:00 EST

Increasing nitrogen emissions from motor vehicles, energy production, and agriculture are being deposited in lakes throughout the world, directly affecting lake biology and associated food webs. Alpine lake ecosystems are especially vulnerable to this deposition. USGS scientist Jill Baron, co-author of two new studies on how increased nitrogen pollution can affect lake ecosystems and water quality, discusses the issue.

U.S. Using Less Water Than It Did 35 Years Ago

David Hebert — Thu, 29 Oct 2009 00:00:00 EST

The United States is using less water than during the peak years of 1975 and 1980, according to USGS water use estimates for 2005. Despite a 30 percent population increase during the past 25 years, overall water use has remained fairly stable.

So what else do we know--and not know--about water use in the U.S.? Learn from a USGS scientist and partners, and hear what they're going to talk about at a water use briefing on Capitol Hill.

Tsunamis: Tides have nothing to do with it

ssobie - at - usgs.gov (Steven Sobieszczyk) — Tue, 27 Oct 2009 00:00:00 EST

Farming Carbon to Help the Atmosphere and the Land

jnickles - at - usgs.gov (James Nickles) — Mon, 29 Sep 2008 00:00:00 EST

Long-standing farming practices in California's Sacramento-San Joaquin River Delta expose fragile peat soils to wind, rain and cultivation, emit carbon dioxide (CO2) and cause land subsidence. To capture or contain the carbon, farmers would "grow" wetlands. In doing so, they would begin to rebuild the Delta's unique peat soils, take CO2 out of the atmosphere, ease pressure on the Delta's aging levees, and infuse the region with new economic potential. We learn more from USGS bio-geochemist Robin Miller about how this could help California, the nation, and the world.
