New evidence shows carbon's importance to ocean life's survival 252 million years ago
A new study led by UT Arlington Earth & Environmental Scientists shows for the first time how carbon offered a mode of survival for some ocean life after one of the greatest mass extinctions in the history of Earth.

NASA catches a tropical cyclone's birth in 3-D
Tropical Cyclone 05W was born in the Northwestern Pacific Ocean on April 3 west of the island of Pohnpei when the GPM satellite passed over it and analyzed its rainfall rates. That GPM data was made into a 3-D image that showed some high thunderstorms northwest of its center.

Virginia Tech, Ecuadoran scientists study rare 'Pinocchio Lizard' in effort to save it
A long lizard nose is an important part of their social interactions and a unique aspect of the natural history of this remarkable lizard. Scientists say the more they know about its behavior, the better the chances they have to save it.

NASA's ISS-RapidScat: Typhoon Maysak's strongest winds tightly wound
The RapidScat instrument that flies aboard the International Space Station saw Typhoon Maysak's strongest winds wrapped tightly around its center, extending outward to over 30 miles from the eye. Maysak weakened as a result of increasing wind shear.

TRMM satellite makes direct pass over Super Typhoon Maysak
The Tropical Rainfall Measuring Mission satellite delivered a remarkable image of Super Typhoon Maysak on March 31. TRMM obtained an image straight over the top of a super typhoon with a double eye-wall, Super Typhoon Maysak, as it roared through the warm waters of the West Pacific south of Guam.

New study finds a natural oil dispersion mechanism for deep-ocean blowout
A first-of-its-kind study observed how oil droplets are formed and measured their size under high pressure. They further simulated how the atomized oil spewing from the Macondo well reached the ocean's surface during the Deepwater Horizon accident.

Ocean-scale dataset allows broad view of human influence on Pacific coral reef ecosystems
A study published today by scientists at the University of Hawai'i at Manoa, the National Oceanic and Atmospheric Administration, and the University of Victoria in the journal PLOS ONE draws on data from nearly 40 islands and atolls across the central and western Pacific, including 25 unpopulated islands, to investigate the relative influence of environmental variation and human presence on reef fish assemblages. The resulting message is sobering.

NOAA study provides detailed projections of coral bleaching

Story tips from the Department of Energy's Oak Ridge National Laboratory, April 2015
By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.

Oxygen-depleted toxic oceans had key role in mass extinction over 200 million years ago
Changes in the biochemical balance of the ocean were a crucial factor in the end-Triassic mass extinction, during which half of all plant, animal and marine life on Earth perished, according to new research involving the University of Southampton.

Agricultural contaminant impacts fish reproductive behavior
A common growth-promoting hormone used worldwide in the cattle industry has been found to affect the sexual behaviors of fish at a very low concentration in waterways -- with potentially serious ecological and evolutionary consequences.

Polar bears unlikely to thrive on land-based foods
Polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey -- ice seals.

Better method for forecasting hurricane season
A better method for predicting the number of hurricanes in an upcoming season has been developed by a team of University of Arizona atmospheric scientists. The UA team's new model improves the accuracy of seasonal hurricane forecasts for the North Atlantic and the Gulf of Mexico by 23 percent. The team's research paper was published online in the journal Weather and Forecasting on March 25.

Bacteria play an important role in the long term storage of carbon in the ocean
The ocean is a large reservoir of dissolved organic molecules, and many of these molecules are stable against microbial utilization for hundreds to thousands of years. They contain a similar amount of carbon as compared to carbon dioxide in the atmosphere. Researchers at the Helmholtz Centre for Environmental Research, the University of South Carolina and the Helmholtz Centre Munich found answers to questions about the origin of these persistent molecules in a study published in Nature Communications.

Scientists discover elusive secret of how continents formed
An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion years ago -- and how those processes have continued within the last 70 million years to profoundly affect the planet's life and climate.

Discovery of 2 new species of primitive fishes
Working with an international team, paleontologists at the University of Zurich have discovered two new species of Saurichthys. The ~242 million year old predatory fishes were found in the fossil Lagerstätte Monte San Giorgio, in Ticino. They are distinct from previously known Saurichthys species in the shape of the head and body, suggesting different habitats and diet.

UNH geologist identifies new source of methane for gas hydrates in Arctic
Researchers have identified a new source of methane for gas hydrates -- ice-like substances found in sediment that trap methane within the crystal structure of frozen water -- in the Arctic Ocean. The findings, published online now in the May 2015 journal Geology, point to a previously undiscovered, stable reservoir for methane that is 'locked' away from the atmosphere, where it could impact global climate change.

Massive study is first to explore historical ocean response to abrupt climate change
A new study reports that marine ecosystems can take thousands, rather than hundreds, of years to recover from climate-related upheavals. The study's authors -- including Peter Roopnarine, Ph.D., of the California Academy of Sciences -- analyzed thousands of invertebrate fossils to show that ecosystem recovery from climate change and seawater deoxygenation might take place on a millennial scale.

NASA's ISS-RapidScat sees Typhoon Maysak's stronger winds become more uniform
A tropical cyclone does not always have consistently strong winds all the way around it, and NASA's ISS-RapidScat instrument confirmed that was the case with Typhoon Maysak as it was strengthening in the Northwestern Pacific Ocean. Over the course of three days, As the tropical cyclone strengthened, RapidScat saw strongest sustained winds around Typhoon Maysak expand and spread from the northern quadrant to other quadrants of the storm.
