From finding Nemo to minerals: What riches lie in the deep sea?
As fishing and the harvesting of metals, gas and oil have expanded deeper and deeper into the ocean, scientists are drawing attention to the services provided by the deep sea, the world’s largest environment.

Impact of Deepwater Horizon oil spill on coral is deeper and broader than predicted
A new discovery of two additional coral communities showing signs of damage from the Deepwater Horizon oil spill expands the impact footprint of the 2010 spill in the Gulf of Mexico.

Noise pollution impacts fish species differently
Acoustic disturbance has different effects on different species of fish, according to a new study that tested fish anti-predator behavior. The current study demonstrates species-specific differences in response to noise, potentially driven by a range of underlying behavioral and physiological mechanisms.

15-year analysis of blue whale range off California finds conflict with shipping lanes
A comprehensive analysis of the movements of blue whales off the West Coast found that their favored feeding areas are bisected by heavily used shipping lanes, increasing the threat of injury and mortality. But moving the shipping lanes off Los Angeles and San Francisco to slightly different areas -- at least, during summer and fall when blue whales are most abundant -- could significantly decrease the probability of ships striking the whales.

Major impact of climate change on Antarctic fur seals
Genetic analysis of Antarctic fur seals, alongside decades of in-depth monitoring, has provided unique insights into the effect of climate change on a population of top-predators. The findings show that the seals have significantly altered in accordance with changes in food availability that are associated with climate conditions. Despite a shift in the population towards 'fitter' individuals, this fitness is not passing down through generations, leaving the population in decline.

Calcification in changing oceans
What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers -- organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection.

Research charts ecological impact of microbial respiration in oxygen-starved ocean
A sulfur-oxidizing bacterial group called SUP05 will play an increasingly important role in carbon and nutrient cycling in the world's oceans as oxygen minimum zones expand, according to research. To conduct this study, researchers plumbed the depth of a seasonally anoxic fjord, Canada's Saanich Inlet, to chart how microbial community metabolism changes as oxygen minimum zones form.

Safeguarding Belize's barrier reef with conservation drones
Seeking to gain a high-tech edge over illegal fishers, the Government of Belize will use “eyes in the sky” to enforce fishing regulations in the biodiverse Glover’s Reef Marine Reserve and other reef systems in what is the first use of conservation drones to monitor marine protected areas.

Vulnerability of sharks as collateral damage in commercial fishing shown by study
A new study that examined the survival rates of 12 different shark species when captured as unintentional bycatch in commercial longline fishing operations found large differences in survival rates across the 12 species, with bigeye thresher, dusky, and scalloped hammerhead being the most vulnerable.

Seals forage at offshore wind farms
By using sophisticated GPS tracking to monitor seals' every movement, researchers have shown for the first time that some individual seals are repeatedly drawn to offshore wind farms and pipelines. Those human-made structures probably serve as artificial reefs and attractive hunting grounds, according to a study.

Microplastics worse for crabs and other marine life than previously thought: Enter through gills
The tiny plastic particles polluting our seas are not only orally ingested by marine creatures, but also enter their systems through their gills, according to a new study. When microplastics are drawn in through this method they take over six times longer to leave the body compared with standard digestion.

Nature's strongest glue comes unstuck
Over a 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue. Still far better than anything we have been able to develop synthetically, barnacle glue -- or cement -- sticks to any surface, under any conditions. But exactly how this superglue of superglues works has remained a mystery -- until now.

Atlantic salmon show capacity to adapt to warmer waters
Populations of Atlantic salmon have a surprisingly good capacity to adjust to warmer temperatures that are being seen with climate change, a group of scientists has discovered. The finding about Atlantic species adds to recent research on heat tolerance of Pacific salmon. The study addressed questions around how climate change might affect salmon species distribution and abundance.

Dredging linked to diseased corals by new study
Dredging activity near coral reefs can increase the frequency of diseases affecting corals. researchers say after a a world-first study. 'At dredging sites, we found more than twice as much coral disease than at our control sites,' says the lead author of the study. "Corals require both light and food to survive," researchers explain. "And unfortunately, dredging impacts corals on two fronts: increased turbidity means less light for photosynthesis, while increased levels of sediment falling onto the coral can interfere with their ability to feed."

Indus river dolphin's declining range: Patterns of river fragmentation provide insight into river dolphin conservation
Removal of river water for irrigation and habitat fragmentation by irrigation dams were shown to be the principal factors contributing to the decline of the Indus river dolphin.

Whale shark fringe migration: 16-year study suggests Azore islands may play increasing role in whale shark habitat
At the fringe of the whale shark range, the volcanic Azore islands may play an increasing role for the north Atlantic population as sea surface temperatures rise.

Animal foraging tactics unchanged for 50 million years
Animals have used the same technique to search for food that's in short supply for at least 50 million years, a new study suggests. Researchers analyzed fossilized sea urchin trails from northern Spain and found the tracks reflect a search pattern still used by a huge range of creatures today.

Glowing red in the big blue: Red fluorescence at great depths
Many fish species glow red and can see red light, even at depths where the red part of the sunlight spectrum has been absorbed by the water above. It was long assumed that red light did not play a role at depths of 10m or more. However, researchers have not only discovered and investigated the phenomenon of red fluorescence; they have now described a new detail which offers important clues to the function of glowing red.

Organic pollutants not factor in turtle tumor disease, study finds
A new study casts doubt on long-held suspicions that persistent organic pollutants in the environment make green turtle more susceptible to the virus that causes fibropapilomatosis, a disease that forms large benign tumors that can inhibit the animal's sight, mobility and feeding ability.

New mite species from a Caribbean mesophotic coral ecosystem named after J-Lo
During a recent survey of organisms collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, one pontarachnid mite species new to science was discovered. The new species was named after the famous Puerto Rican singer Jennifer Lopez.
