R.I. nitrogen cycle differs in bay and sound
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences between bay and sound sediments, but that raises new questions about what's going on in the Bay to account for those.

Geology
What lies beneath modern New England? Mountain-building and the end of an ancient ocean
When and where did the ancient Iapetus Ocean suture (the most fundamental Appalachian structure) form? Is part of New England made up of ancient African-derived rocks? What is the Moretown terrane? This new Geology study by researchers from Harvard, Middlebury College, Boise State University, and Williams College finds new evidence for an earlier closing of the Iapetus that is farther west than previous studies have reported.

Important migratory corridor for endangered marine species off north-west Australia
The value of Australia's newly established network of marine parks has been highlighted by an international project that used satellites to track the vulnerable flatback sea turtle. Researchers from Deakin University (Australia), Swansea University (United Kingdom) and Pendoley Environmental consultancy used advanced satellite tracking systems to record the passage of more than 70 flatbacks off the north-west Australian coastline. The network of Australian marine reserves may also serve as a template for marine conservation elsewhere in the world.

Metabolism may have started in our early oceans before the origin of life
The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events leading to the origin of life. Wellcome-Trust funded researchers reconstructed the chemical make-up of the earth's earliest ocean and found the spontaneous occurrence of reaction sequences which in modern organisms are essential for the synthesis of organic molecules critical for the cellular metabolism seen in all living organisms.

Microscopic organism plays a big role in ocean carbon cycling, Scripps scientists discover
Scientists at Scripps Institution of Oceanography at UC San Diego have taken a leap forward in understanding the microscopic underpinnings of the ocean carbon cycle by pinpointing a bacterium that appears to play a dominant role in carbon consumption.

Two new US turtle species described
The alligator snapping turtle is the largest river turtle in North America, weighing in at up to 200 pounds and living almost a century. Now researchers from Florida and the University of Vermont have discovered that it is not one species -- but three. One of the new species lives only in the Suwannee River and is highly imperiled.

Too many chefs: Smaller groups exhibit more accurate decision-making
The trope that the likelihood of an accurate group decision increases with the abundance of brains involved might not hold up when a group faces a variety of factors, Princeton University researchers report. Instead, smaller groups actually tend to make more accurate decisions while larger assemblies may become excessively focused on only certain pieces of information.

Scientists identify source of mysterious sound in the Southern Ocean
Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the 'bio-duck,' is the Antarctic minke whale (Balaenoptera bonaerensis). First described and named by submarine personnel in the 1960s who thought it sounded like a duck, the bio-duck sound has been recorded at various locations in the Southern Ocean, but its source has remained a mystery, until now.

AGU: Odds of storm waters overflowing Manhattan seawall up 20-fold, new study shows
Maximum water levels in New York harbor during major storms have risen by nearly two and a half feet since the mid-1800s, making the chances of water overtopping the Manhattan seawall now at least 20 times greater than they were 170 years ago, according to a new study.

Connecticut River watershed study will assess impacts of extreme rain events
A team of Yale researchers will lead a five-year, $3 million study to determine whether an increase in extreme rain events is affecting the transport of dissolved organic matter through the Connecticut River watershed, a phenomenon they say could alter the chemical composition and water quality of the watershed and Long Island Sound. The grant is funded by the National Science Foundation's MacroSystems Biology program.

New electric fish genus and species discovered in Brazil's Rio Negro
Discovery of a new species of electric knife fish in the Amazon Basin in Brazil is leading to a new interpretation of classifications and interrelationships among closely related groups. As the diversity of electric fishes becomes more thoroughly documented, researchers will be able to explore possible causes of this group's adaptive radiation over evolutionary time.

Ancient sea-levels give new clues on ice ages
International researchers, led by the Australian National University (ANU), have developed a new way to determine sea-level changes and deep-sea temperature variability over the past 5.3 million years. The findings will help scientists better understand the climate surrounding ice ages over the past two million years, and could help determine the relationship between carbon dioxide levels, global temperatures and sea levels.
