NOAA led study: Crude oil causes developmental abnormalities in large marine fish
Crude oil from the 2010 Deepwater Horizon disaster causes severe defects in the developing hearts of bluefin and yellowfin tunas, according to a new study by a team of NOAA and academic scientists. The findings, published in the Proceedings of the National Academy of Sciences on the 25th anniversary of the Exxon Valdez oil spill, show how the largest marine oil spill in United States history may have affected tunas and other species that spawned in oiled offshore habitats in the northern Gulf of Mexico.

New study shows heart abnormalities in fish embryos exposed to Deepwater Horizon oil
A new study showed that several Gulf of Mexico fish embryos developed serious defects in heart development following exposure to crude oil from the Deepwater Horizon oil spill. The study is the first to analyze the effects of the primary toxic agents released from crude oil on several commercially important pelagic fish species that spawn in the Gulf of Mexico.

Wayne State receives grant to advance ecological restoration efforts in the Great Lakes
Foreign mussels hitchhiking to the Great Lakes in the ballast water tanks of international freighters are becoming one of the most vexing environmental problems facing the Great Lakes. A group of scientists from Wayne State University, in collaboration with the United States Geological Survey and the Environmental Protection Agency, are working together to battle this problem.

Deep ocean current may slow due to climate change, Penn research finds
A new study by the University of Pennsylvania's Irina Marinov and Raffaele Bernardello and colleagues from McGill University has found that recent climate change may be acting to slow down one of the ocean's 'conveyer belts,' with potentially serious consequences for the future of the planet's climate.

Science
Dust in the wind drove iron fertilization during ice age
A study published in Science by researchers at Princeton University and ETH Zurich confirms a longstanding hypothesis that wind-borne dust carried iron to the region of the globe north of Antarctica, driving plankton growth and eventually leading to the removal of carbon dioxide from the atmosphere.

Ancient clam gardens nurture food security
A three-year study of ancient clam gardens in the Pacific Northwest has led researchers, including three from Simon Fraser University, to make a discovery that could benefit coastal communities' food production. PLOS ONE, a peer-reviewed science journal, has just published their study. The researchers discovered that ancient clam gardens made by Aboriginal people produced quadruple the number of butter clams and twice the number of littleneck clams as unmodified clam beaches.

Tracking endangered leatherback sea turtles by satellite, key habitats identified
Most satellite tagging studies of leatherbacks have focused on adult females on their tropical nesting beaches, so little is known worldwide about males and subadults, the researcher point out. But now, tagging and satellite tracking in locations where leatherbacks forage has allowed the scientists to get a much richer picture of the leatherback's behavior and dispersal patterns on the open ocean.

New airborne GPS technology for weather conditions takes flight
A new technique led by a researcher at Scripps Institution of Oceanography at UC San Diego stands to improve weather models and hurricane forecasting by detecting precise conditions in the atmosphere through a new GPS system aboard airplanes. The first demonstration of the technique, detailed in the journal Geophysical Research Letters, is pushing the project's leaders toward a goal of broadly implementing the technology in the near future on commercial aircraft.

Humans drive evolution of conch size
Smithsonian scientists found that 7,000 years ago, the Caribbean fighting conch contained 66 percent more meat than its descendants do today. Because of persistent harvesting of the largest conchs, it became advantageous for the animal to mature at a smaller size, resulting in evolutionary change.

Oceanography
New statistical models could lead to better predictions of ocean patterns
The world's oceans cover more than 72 percent of the earth's surface, impact a major part of the carbon cycle, and contribute to variability in global climate and weather patterns. Now, researchers at the University of Missouri applied complex statistical models to increase the accuracy of ocean forecasting that influences the ways in which forecasters predict long-range events such as El Nińo and the lower levels of the ocean food chain.

Cultural hitchhiking: How social behavior can affect genetic makeup in dolphins
A UNSW-led team of researchers studying bottlenose dolphins that use sponges as tools has shown that social behavior can shape the genetic makeup of an animal population in the wild. The research on dolphins in Shark Bay in Western Australia is one of the first studies to show this effect -- which is called cultural hitchhiking -- in animals other than people. The research is published in the journal Proceedings of the Royal Society B.

UCLA geographers create 'easy button' to calculate river flows from space
The frustrated attempts of a UCLA graduate student to quantify the amount of water draining from Greenland's melting ice sheet led him to discover a new way to measure river flows from outer space, he and his professor report in a new study. The new approach relies exclusively on measurements of a river's width over time, which can be obtained from freely available satellite imagery.
