As waters clear, scientists seek to end a muddy debate
12-13-2007 · EurekAlert!Geologists have long thought muds will only settle when waters are quiet, but new research by Indiana University Bloomington and Massachusetts Institute of Technology geologists shows muds will accumulate even when currents move swiftly. Their findings appear in this week's Science.

- Study finds fecal microbes high in New Orleans sediments following Hurricanes Katrina and Rita
05-03-2007 · EurekAlert!
In a new study documenting the microbial landscape of New Orleans and Lake Pontchartrain in the wake of Hurricanes Katrina and Rita, scientists report that sediments in interior portions of the city appear to be contaminated with fecal microbes, a chronic condition they say persisted in the area before the hurricanes, and that the resulting water quality in the city and in nearshore waters of the lake continues to be impacted by discharges from this contamination.

- Protecting our beaches
09-03-2007 · EurekAlert!
Bathing beaches and lakes could fail the new cleanliness standards set by the 2006 Bathing Waters Directive, but a new risk assessment tool developed by rural studies and water management experts may help reduce the transfer of disease causing bacteria from the farmed environment, according to scientists speaking today, Sept. 4, 2007, at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs Sept. 3-6, 2007.

- CO2 emissions could violate EPA ocean-quality standards within decades
09-19-2007 · EurekAlert!
In a commentary in the Sept. 25, 2007, issue of the Geophysical Research Letters, a large team of scientists state that human-induced carbon dioxide emissions will alter ocean chemistry to the point where it will violate US Environmental Protection Agency Quality Criteria (1976) by mid-century if emissions are not dramatically curtailed now. This is the first recognition that atmospheric CO2 emissions will cause ocean waters to violate EPA water quality criteria.

- Researchers Setting Up Observatories to Examine Arctic Changes from Under the Ice
04-16-2007 · Woods Hole Oceanographic Institution (WHOI)
WHOI researchers are venturing to the North Pole to deploy instruments
that will make year-round observations of the water beneath the Arctic
ice cap. Scientists will investigate how the waters in the upper layers
of the Arctic Ocean are changing from season to season and year to year
as global climate fluctuates.

- Salty oceans provide early warning for climate change
06-08-2007 · EurekAlert!
Monitoring the saltiness of the ocean water could provide an early indicator of climate change. Significant increases or decreases in salt in key areas could forewarn of climate change in 10 to 20 years time. Presenting their findings at a recent European Science Foundation (ESF) conference, scientists predicted that the waters of the southern hemisphere oceans around South Africa and New Zealand are the places to watch.

- Researchers setting up observatories to examine changes under the Arctic ice
04-16-2007 · EurekAlert!
Researchers from the Woods Hole Oceanographic Institution are venturing this month to the North Pole to deploy instruments that will make year-round observations of the water beneath the Arctic ice cap. Scientists will investigate how the waters in the upper layers of the Arctic Ocean -- which insulate surface ice from warmer, deeper waters -- are changing from season to season and year to year as global climate fluctuates.

- 2 MSU professors spearhead international water project
06-22-2007 · EurekAlert!
Two MSU professors are leading an international partnership of environmental engineers and scientists from four research universities, including U.S., to purify the world’s waters. With the biggest funding of its kind -- a $2.5 million grant -- by the National Science Foundation, the team leaders are bringing together domestic and international expertise, as well as investing in students, to develop water purifying strategies using what are called “membrane-based” technologies.

- Scientists seek to assess the microbial risks in the water we drink
12-11-2007 · EurekAlert!
Disease outbreaks sometimes originate from a source that most people in the United States and other developed countries trust unquestioningly: drinking water. However, there is much we do not know about the causes and likelihood of waterborne illness, and we can and should do more to assess the risks, according to a new report, Clean Water: What is Acceptable Microbial Risk?, released by the American Academy of Microbiology.

- Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.

- Genome-wide search unearths surprising clues for diabetes and triglycerides
04-26-2007 · EurekAlert!
Scientists from the Broad Institute of Harvard and MIT, Lund University and Novartis today announced the discovery of three unsuspected regions of human DNA that contain clear genetic risk factors for type 2 diabetes, and another that is associated with elevated blood triglycerides. The study is among the first to apply a suite of genomic resources to clinical research, including the Human Genome Project, the SNP and HapMap Projects, and genome-scale laboratory and analytical tools.
