JPL, Caltech, Smithsonian scientists improve methodology for monitoring HOx radicals

Scientists have unraveled a mystery about hydrogen peroxide that may lead to a more accurate way of measuring a gas that contributes to depletion of Earth's ozone layer.

New Marine Science Program Will Use the World as Its Lab

New Environmental Science and Engineering program will span the fields of geology, engineering, and chemistry, and give undergraduates experience in field based research.

Environmental Study of Local Area Conducted by Caltech Team

California Institute of Technology researchers have received a $100,000 grant from the Alice C. Tyler Perpetual Trust to study the human impact on land and water in the San Gabriel Valley and San Gabriel River watershed. Ecosystems bordering major metropolitan areas are subject to intense pressures from pollutants produced by transportation, industrial activities, power generation, and recreational activities. This project will measure and document these environmental changes in order to predict future impacts.

Scientists achieve breakthrough in fuel-cell technology

Gasoline averaging $3 per gallon? Oil drilling in an Alaskan wildlife reserve? A need to relax air quality standards? It seems the long-term future of fossil fuels is bleak. One promising solution scientists have been studying is fuel cells, but they've had limitations too. Now, in the April 19 issue of the science journal Nature, the California Institute of Technology's Sossina M. Haile reports on a new type of fuel cell that may resolve these problems.

Scientists Watch Dark Side of the Moon to Monitor Earth's Climate

Scientists have revived and modernized a nearly forgotten technique for monitoring Earth's climate by carefully observing "earthshine," the ghostly glow of the dark side of the moon.

Earthshine measurements are a useful complement to satellite observations for determining Earth's reflectance of sunlight (its albedo), an important climate parameter. Long-term observations of earthshine thus monitor variations in cloud cover and atmospheric aerosols that play a role in climate change.

Caltech Professor Cited for Insights into Atmospheric Phenomena

PASADENA, Ca.- The chemical constituents of Earth's atmosphere are linked together in a complex way. A subtle alteration of one can make significant, often counterintuitive changes to another. For his work in unraveling some of the knotty complexity involved in such atmospheric processes, the California Institute of Technology's John H. Seinfeld has been awarded the Desert Research Institute's 2001 Nevada Medal.

Caltech receives a $10 million grant from BP to conduct methane research.

Packard Foundation Gives Caltech $1 Million

Caltech receives a $1 million grant from the David and Lucile Packard Foundation Science Program.

Caltech Environmental Task Force to Celebrate Earth Day

For Immediate Release April 14, 2000

PASADENA—The California Institute of Technology Environmental Task Force will host the annual Caltech Earth Day Fair Friday, April 21, from 11: 30 a.m. to 2 p.m. outside the Winnett Student Center. It is free and open to the public.

Biological Activity the Likely Culprit of Atmospheric Nitrous Oxide Increases

New research suggests that the changing concentration of nitrous oxide in the atmosphere is largely a result of biological activity.
