Many Dry Tortugas loggerheads actually Bahamas residents
Many loggerhead sea turtles that nest in Dry Tortugas National Park head to rich feeding sites in the Bahamas after nesting, a discovery that may help those working to protect this threatened species.

Genetics provides new clues about lionfish invasion
New genetic data suggest the red lionfish invasion in the Caribbean Basin and Western Atlantic started in multiple locations, not just one as previously believed, according to a new study led by the US Geological Survey.

Dolphins use extra energy to communicate in noisy waters
Dolphins that raise their voices to be heard in noisy environments expend extra energy in doing so, according to new research that for the first time measures the biological costs to marine mammals of trying to communicate over the sounds of ship traffic or other sources.

How oil damages fish hearts: Five years of research since the Deepwater Horizon oil spill
Scientists have shown that toxic compounds in oil target the still-forming hearts of larval fish, leading to developmental defects and reduced survival.

Thawing permafrost feeds climate change
Assistant Professor of Oceanography Robert Spencer writes in Geophysical Research Letters that single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide. Increased carbon dioxide levels, of course, cause the Earth to warm and accelerate thawing.

Study: Photosynthesis has unique isotopic signature
Photosynthesis leaves behind a unique calling card, a chemical signature that is spelled out with stable oxygen isotopes, according to a new study in Science. The findings suggest isotopic signatures could exist for many biological and geological processes, including some that are difficult to observe with current tools.

DNA of bacteria crucial to ecosystem defies explanation
The genome of an important bacteria contains far more 'junk DNA' than scientists expected -- making its genome more closely resemble that of a higher lifeform.

UNH researchers discover new method to detect most common bacteria contaminating oysters
In a major breakthrough in shellfish management and disease prevention, researchers at the University of New Hampshire have discovered a new method to detect a bacterium that has contaminated New England oyster beds and sickened consumers who ate the contaminated shellfish. The new patent-pending detection method - which is available for immediate use to identify contaminated shellfish -- is a significant advance in efforts to identify shellfish harboring disease-carrying strains of Vibrio parahaemolyticus.

First invasive lionfish discovered in Brazil
A single fish caught with a hand spear off the Brazilian coast is making big waves across the entire southwestern Atlantic. In May 2014, a group of recreational divers spotted an adult lionfish -- the voracious invader Pterois volitans -- in the rocky reefs of southeastern Brazil.

Majorities in Arctic nations favor cooperation with Russia despite Ukraine; conflict worries rise
Commissioned by the Gordon Foundation of Toronto and Institute of the North, Anchorage, a survey of 10,000 respondents in countries with Arctic territory reveals major differences of opinion on issues ranging from Arctic co-operation with Russia to the threat of military conflict north of the 60th parallel, to whether the Northwest Passage is a Canadian or international waterway. Tables of the survey results are here:

Calculating how the Pacific was settled
Using statistics that describe how an infectious disease spreads, a University of Utah anthropologist analyzed different theories of how people first settled islands of the vast Pacific between 3,500 and 900 years ago. Adrian Bell found the two most likely strategies were to travel mostly against prevailing winds and seek easily seen islands, not necessarily the nearest islands.

Fishing impacts on the Great Barrier Reef
New research shows that fishing is having a significant impact on the make-up of fish populations of the Great Barrier Reef. Researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University have found that removing predatory fish such as coral trout and snapper, through fishing, causes significant changes to the make-up of the reef's fish populations.

Phytoplankton, reducing greenhouse gases or amplifying Arctic warming?
Scientists with Pohang University of Science and Technology (POSTECH), Max Planck Institute for Meteorology, and Korea Institute of Ocean Science and Technology, presented on Monday, April 20, in Proceedings of National Academy of Sciences online, the geophysical impact of phytoplankton that triggers positive feedback in the Arctic warming when the warming-induced melting of sea ice stimulates phytoplankton growth. The paper is titled 'Amplified Arctic warming by phytoplankton under greenhouse warming.'

Extending climate predictability beyond El Niño
Tropical Pacific climate variations and their global weather impacts may be predicted much further in advance than previously thought, according to research by an international team of climate scientists from the USA, Australia, and Japan. The source of this predictability lies in the tight interactions between the ocean and the atmosphere and among the Atlantic, the Pacific and the Indian Oceans. Such long-term tropical climate forecasts are useful to the public and policy makers.

Ocean currents impact methane consumption
Offshore the Norwegian Svalbard archipelago, methane is seeping out of the seabed in several hundred meters depth. Luckily, bacteria are consuming a large proportion of the methane before it is released to the atmosphere, where it acts as a greenhouse gas. An interdisciplinary study conducted by researchers at the University of Basel and the GEOMAR Helmholtz Centre for Ocean Research Kiel could now show that ocean currents can have a strong impact on methane removal. The renowned journal Nature Geoscience has published the study.

Pruning of blood vessels: Cells can fuse with themselves
Cells of the vascular system of vertebrates can fuse with themselves. This process, which occurs when a blood vessel is no longer necessary and pruned, has now been described on the cellular level by Professor Markus Affolter from the Biozentrum of the University of Basel. The findings of this study have been published in the journal PLOS Biology.

Vampire squid discovery shows how little we know of the deep sea
Among soft-bodied cephalopods, vampire squid live life at a slower pace. At ocean depths from 500 to 3,000 meters, they don't swim so much as float, and they get by with little oxygen while consuming a low-calorie diet of zooplankton and detritus. Now, researchers reporting in the Cell Press journal Current Biology on April 20 have found that vampire squid differ from all other living coleoid cephalopods in their reproductive strategy as well.

Model offers more ease, precision for managing invasive Asian carp
The likelihood of Asian carp eggs being kept in suspension and hatching in the St. Joseph River in Michigan has been further evaluated using a model that examines a range of multiple flow and water temperature scenarios. Results illustrate the highest percentage of Asian carp eggs at risk of hatching occurs when the streamflow is low and when the water temperature is high.

Fish type, body size can help predict nutrient recycling rates
The nutrients excreted by fish in their 'pee' may be critical to the health of coastal ecosystems. But knowing whether generalizations can be made about how to predict these nutrient levels in various ecosystems has vexed researchers -- until now.

Repeated marine predator evolution tracks changes in ancient and Anthropocene oceans
A team of Smithsonian scientists synthesized decades of scientific discoveries to illuminate the common and unique patterns driving the extraordinary transitions that whales, dolphins, seals and other species underwent as they moved from land to sea. Drawing on recent breakthroughs in diverse fields such as paleontology, molecular biology and conservation ecology, their findings offer a comprehensive look at how life in the ocean has responded to environmental change from the Triassic to the Anthropocene.
