A geophysics team from the University of Haifa has identified a series of active gas springs on the Haifa Bay sea floor. “Geophysical information enables us to map out the entire system,” says Dr. Uri Schattner, head of the Department of Marine Geosciences.
Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by NCAR. The findings could provide a breakthrough in the longstanding quest to narrow the range of expected global warming.
Corals under attack by toxic seaweed do what anyone might do when threatened – they call for help. A study reported this week in the journal Science shows that threatened corals send signals to fish “bodyguards” that quickly respond to trim back the harmful seaweed.
The 1930s Dust Bowl was a singular event in U.S. history, but Dust Bowl-like droughts and conditions do still occur. Experts are available to discuss what events like the 2012 U.S. drought mean for us now and how we can prepare for similar events in the future.
Most species loss in Bahamas and Greater Antilles explained by loss of land area.
Israel’s first research center for Green Roofs Ecology research will focus on research and development of non-irrigated green roofs that are suitable for Middle Eastern climates; improving biological diversity with green roofs; and developing ecological theories.
Twenty years after its inception, the continued need for water quality improvement has led to a call for further advancement of the Phosphorus Index.
U.S. Forest Service and Oak Ridge National Laboratory scientists have found that rising levels of ozone may amplify the impacts of higher temperatures and reduce streamflow from forests to rivers, streams and other water bodies. A committee formed by the National Academy of Sciences and the National Research Council has released a report (http://www.nap.edu/catalog.php?record_id=13430) of recommendations to accelerate climate modeling to learn more about climate’s regional ramifications and future effects. When four of the nation’s most energy-efficient houses are sold, the new homeowners can opt to allow the research project to continue, providing additional data that could make houses of tomorrow even better. Ethanol blends of 10 to 25 percent could potentially have more fuel pump compatibility issues than higher blends, according to a study conducted by a team led by Mike Kass of Oak Ridge National Laboratory’s Fuels and Engines Research Group.
What is the best course of action when an invading noxious weed threatens to attack crop yields and assault grazing land? Invite a friend to dinner. In this case, the friend is a plant-eating insect—the stem-mining weevil.
A sophisticated study of sea level rise related to global warming shows that flooding and damage to D.C. buildings and infrastructure could be extensive in the next 100 years, particularly during storms.
The St. Francois Mountains, in the southeastern part of Missouri, are home to the state’s highest peaks and only igneous glades. This unique area harbors a diverse flora that is currently under threat from encroaching species. Concern for survival of the glade’s plant communities has prompted a study that will lead to mapping out a conservation management plan.
The Cretaceous Period of Earth history ended with a mass extinction that wiped out numerous species, most famously the dinosaurs. A new study now finds that the structure of North American ecosystems made the extinction worse than it might have been.
Fisheries expert and executive director of Institute for Ocean Conservation Science at Stony Brook University presents assessment of current fisheries management in the journal Science.
In a Perspectives article, “The Risks of Overfishing,” published in the October 26 issue of the journal Science, Dr. Ellen K. Pikitch, executive director of the Institute for Ocean Conservation Science and professor at Stony Brook University, cautions against continuing traditional fisheries management.
Even if the weather outside is frightful, solar cells can still generate a delightful amount of electricity.
Initial results of clay samples from western North Dakota show varying percentages of alumina content, a finding of interest to the North Dakota Geological Survey that commissioned the study. Scientists in a lab at North Dakota State University’s Center for Nanoscale Science and Engineering (CNSE), Fargo, are completing analysis of the clay, often referred to as kaolin, which could eventually play a role in proppants used for hydraulic fracturing in North Dakota oil exploration.
Scientists have published the first range-wide genetic analysis of the bowhead whale using hundreds of samples from both modern populations and archaeological sites used by indigenous Arctic hunters thousands of years ago.
Even small increases in temperature from global warming are causing climatology shifts harmful to ocean life, a new study in the Proceedings of the National Academies of Science shows.
A new study co-authored by the Wildlife Conservation Society identifies countries most vulnerable to declining coral reef fisheries from a food-security perspective while providing a framework to plan for alternative protein sources needed to replace declining fisheries.
