New laboratory to study the oceans and air
November 21, 2003Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate.
Examples include ocean uptake of greenhouse gases such as carbon dioxide and production of tiny atmospheric particles from gases emitted by marine algae which can have large impacts on climate. To date there has been little research on these kinds of exchanges particularly in remote ocean areas.
"Greenhouse gas emissions and ozone depletion are now recognised threats, these new facilities will help us to address some of these problems and answer some of the current unknowns," said Professor Tim Jickells, Director of the Laboratory for Global Marine and Atmospheric Chemistry (LGMAC).
LGMAC houses state-of-the-art facilities including an ultra-clean laboratory for the study of air and water composition, measuring minute quantities free from the impact of local pollution such as car fumes. There is also a specialist laboratory for the use of lasers to study atmospheric chemical reactions.
A trace gas laboratory in LGMAC, with simulated Antarctic conditions, will allow the study of ancient ice cores. These ice cores contain tiny trapped bubbles of air, which when released can tell us more about past climatic conditions, in turn helping improve predictions of future climate.
The LGMAC facilities, worth £7m, were funded through a successful bid to the Government's Joint Infrastructure Fund (JIF).
The Laboratory for Global Marine and Atmospheric Chemistry will be opened on Friday November 28 by Nobel Prize-winner Professor Paul Crutzen. Professor Paul Crutzen shared the 1995 Nobel Prize for Chemistry for his work on atmospheric chemistry, particularly the formation and decomposition of ozone.

As Americans prepare for a day without cigarettes and tobacco products as part of the American Cancer Society Great American Smokeout (R) (November 20), new research gives them more reasons to extend that break to a lifetime.
Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.
Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes.
2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006.
International Field Campaign examines impact of beetle kill on Rocky Mountain weather, air quality
Mountain pine beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.
Pine Bark Beetles Affecting More than Forests
Pine bark beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.
IMPACTS: On the Threshold of Abrupt Climate Changes
Abrupt climate change is a potential menace that hasn't received much attention. That's about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy's Office of Biological and Environmental Research (OBER) recently launched IMPACTS - Investigation of the Magnitudes and Probabilities of Abrupt Climate Transitions - a program led by William Collins of Berkeley Lab's Earth Sciences Division (ESD) that brings together six national laboratories to attack the problem of abrupt climate change, or ACC.
Pollution, everyday allergens, may be sources of laryngitis
Everyday exposure to environmental tobacco smoke, allergens, and air pollution may be the root of chronic cases of laryngitis, says new research presented at the 2008 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL.
Breaking harmful bonds
Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes.
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight.
