Warmer oceans could raise mercury levels in fish
Rising ocean surface temperatures caused by climate change could make fish accumulate more mercury, increasing the health risk to people who eat seafood, Dartmouth researchers and their colleagues report in a study in the journal PLOS ONE.

Native tribes' traditional knowledge can help US adapt to climate change
New England's Native tribes, whose sustainable ways of farming, forestry, hunting and land and water management were devastated by European colonists four centuries ago, can help modern America adapt to climate change.

Genetic study of river herring populations identifies conservation priorities
A genetic and demographic analysis of river herring populations along the US east coast has identified distinct genetic stocks, providing crucial guidance for efforts to manage their declining populations. River herring include two related species, alewife and blueback herring, which migrate between freshwater spawning grounds and the ocean. The species are important for both ecological and economic reasons.

Accurate maps of streams could aid in more sustainable development of Potomac River watershed
Where a stream ends is clear, but where it begins can be more difficult to discern. Researchers from the University of Maryland Center for Environmental Science have developed a new method to solve this problem, resulting in a new map of the Potomac River watershed stream network that significantly improves the information needed for assessing the impact of urbanization on aquatic ecosystems.

Rare research into false killer whales reveals anti-predator partnerships
False killer whales (Pseudorca crassidens) are one of the least studied species of ocean dolphin, but new light has been cast on their behavior by a team of marine scientists from New Zealand. The research, published in Marine Mammal Science, reveals how a population off the coast of New Zealand has developed a relationship with bottlenose dolphins to defend themselves from predation.

October GSA Today: Earth upon Impact
In the October issue of GSA Today, Grant Young of the University of Western Ontario discusses the possible causes of the numerous glaciations that characterized the Neoproterozoic and concludes that a dramatic shift in Earth's climate may have occurred during the Ediacaran, in part due to a large marine impact. According to Young, this shift separates Proterozoic glaciations, which were likely triggered by the effect of supercontinent assembly and breakup on atmospheric carbon dioxide levels.

Longline fishery in Costa Rica kills thousands of sea turtles and sharks
The second-most-common catch on Costa Rica's longline fisheries in the last decade was not a commercial fish species. It was olive ridley sea turtles. These lines also caught more green turtles than most species of fish. These findings and more, reported in the Journal of Experimental Marine Biology and Ecology, indicate that the Costa Rican longline fishery represents a major threat to the survival of eastern Pacific populations of sea turtles as well as sharks.

Understanding soil nitrogen management using synchrotron technology
Increasing the organic matter in soils is key to growing crops for numerous reasons, including increased water-holding capacity and improved tilth. Scientists have recently used the Canadian Light Source to evaluate the effects of various sources of supplemental nitrogen fertilizer on the chemical composition of soil organic matter. Results of their experiments to study this question were recently published in the journal Biogeochemistry.

New technique helps biologists save the world's threatened seagrass meadows
Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world's seagrass meadows.

Cold, salty and promiscuous -- Gene-shuffling microbes dominate Antarctica's Deep Lake
Antarctica's Deep Lake is a saltwater ecosystem that remains liquid in extreme cold. For the first time, researchers describe a complete ecological picture of the microbial community thriving in Deep Lake. The detailed analysis appeared in the journal Proceedings of the National Academy of Sciences the week of September 30, 2013 and was led by scientists from the University of New South Wales, Australia partnered with the US Department of Energy Joint Genome Institute.

Eilat's corals stand better chance of resilience than other sites
Israel's southern Red Sea resort of Eilat, one of whose prime attractions is its colorful and multi-shaped underwater coral reefs, may have a clear advantage in the future over rival coral-viewing sites around the world, scientists at the Hebrew University of Jerusalem and Bar-Ilan University have found.

Breathing underwater: Evidence of microscopic life in oceanic crust
Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere" beneath the sea floor is able to survive and thrive. The new research findings were published in the journal Nature Communications on September 27, 2013, and are helping to redefine our concepts of the limits of life on our planet.

Research reveals bottom feeding techniques of tagged humpback whales in Stellwagen Bank Sanctuary
New NOAA-led research on tagged humpback whales in Stellwagen Bank National Marine Sanctuary reveals a variety of previously unknown feeding techniques along the seafloor. Rather than a single bottom feeding behavior, the whales show three distinct feeding approaches: Simple side-rolls, side-roll inversions, and repetitive scooping. A recently published paper, in the journal Marine Mammal Science, indicates that bottom side-roll techniques are common in Stellwagen Bank National Marine Sanctuary and the Great South Channel study area between Nantucket and Georges Bank.

Future sea level rises should not restrict new island formation in the Maldives
The continued accumulation of sand within the iconic ring-shaped reefs inside Maldivian atolls could provide a foundation for future island development new research suggests. Islands like the Maldives are considered likely to be the first to feel the effects of climate change induced sea level rise, with future island growth essential to counter the threat of rising sea levels.

Can bacteria combat oil spill disasters?
Teams of international scientists have decrypted the effectiveness of two types of bacteria, which could be used in the future to help combat oil spill disasters. According to a report (in Applied and Environmental Microbiology), Alcanivorax borkumensis converts hydrocarbons into fatty acids which then form along the cell membrane. New insights on the bacteria Oleispira antarctica are important to understand their adaptation to low temperatures (in Nature Communications).

Study finds steroids may persist longer in the environment than expected
Certain anabolic steroids and pharmaceutical products last far longer in the environment than previously known, according to a new study led by the University of Iowa. The researchers found that the steroid trenbolone acetate, along with some other pharmaceutical products, never fully degrade in the environment, and in fact can partially regenerate themselves. Results published online in the journal Science.
