Spotlight on marine litter
The current state of research and of research gaps concerning litter in our oceans is presented in the new open-access book 'Marine Anthropogenic Litter,' published by Springer. Estimates of the amount of litter in the world's oceans, its distribution, effects on humans and biota, and prevention strategies are just some of the topics addressed in the book. Experts from around the globe have contributed their knowledge to this book.

Trouble in the tide pools
A harmful algal bloom is the suspected culprit of a die-off in 2011 of millions of purple sea urchins and six-starred sea stars in Northern California. Their disappearance is predicted to have long-term ecological consequences on their populations. As algal blooms are expected to increase with climate change and ocean acidification, similar mass mortality events are expected to increase.

Frogs face virus risk in garden ponds
Pond owners are being urged not to use garden chemicals, or to release goldfish into ponds, because of the risk they could pose to wild frogs. Researchers from the University of Exeter found that the severity of ranavirosis, a devastating disease that kills thousands of frogs each year, increases in the presence of exotic fish. The use of garden chemicals was also associated with increased severity of the disease.

Pregnant pipefish fathers are not super dads
Few fathers experience pregnancy, but pipefish dads are one exception and it was assumed that they gave their young a head start in life by providing an abundant oxygen supply. However, it now turns out that this assumption is not true: they supply much less oxygen than thought, and when oxygen is scarce the fathers pay the price -- losing weight and condition -- for their young.

How a box jellyfish catches fish
The first feeding study of tropical Australia's Irukandji box jellyfish has found that they actively fish. They attract larval fish by twitching their extended tentacles, highlighting their nematocyst clusters (stinging structures) and using them as lures. It's an impressive feat by any standards, but particularly so for an animal that doesn't have a defined brain.

MBARI researchers discover deepest high-temperature hydrothermal vents in Pacific Ocean
In spring 2015, MBARI researchers discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico. Lying more than 3,800 meters (12,500 feet) below the surface, the Pescadero Basin vents are the deepest high-temperature hydrothermal vents ever observed in or around the Pacific Ocean.

Great Barrier Reef marine reserves combat coral disease
A new and significant role for marine reserves on the Great Barrier Reef has been revealed, with researchers finding the reserves reduce the prevalence of coral diseases. It's been known for some time that marine reserves are important for maintaining and enhancing fish stocks, but this is the first time marine reserves have been shown to enhance coral health on the Great Barrier Reef.

Many endangered species are back -- but face new struggles
A study of marine mammals finds that several once endangered species, including the humpback whale, the northern elephant seal and green sea turtles, have recovered and are repopulating their former ranges. But returning species create a new challenge: some people interpret the return of these animals as a hostile invasion. The study presents strategies for 'lifting baselines' to help manage and celebrate recovering species.

In a study of the effects of increasing climate temperatures on the toxicity of three contaminants in different fish species, researchers found that all pesticides and industrial contaminants studied became toxic.

Ancient algae found deep in tropical glacier

The ebb and flow of Greenland's glaciers
In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, also advance and retreat with the seasons. Now, a new analysis shows some important connections between these seasonal patterns, sea ice cover and longer-term trends.

Hitchhiking to Caribbean coral

Some endangered sawfishes are having babies, no sex required
Some female members of a critically endangered species of sawfish are reproducing in the wild without sex. The discovery, reported in the Cell Press journal Current Biology on June 1, marks the first time living offspring from 'virgin births' have been found in a normally sexually reproducing vertebrate in the wild, the researchers say.

Invasive microbe protects corals from global warming, but at a cost
An invasive species of symbiotic micro-alga has spread across the Caribbean Sea, according to an international team of researchers. These single-cell algae, which live within the cells of coral animals, are improving the resilience of coral communities to heat stress caused by global warming, but also are diminishing the abilities of corals to build reefs.

How did LIPs form and what is their impact?
The origin, evolution, and environmental impact of large igneous provinces represents a topic of high scientific importance because the magmatism associated with these features cannot be directly related to plate tectonics, and because the eruption of flood basalts may have global environmental consequences. Oceanic LIPs are even more poorly understood due to their relative inaccessibility.

Collision course: ONR testing high-speed planing hulls to better understand wave slam
Earlier this month, scientists sponsored by the Office of Naval Research performed experiments to better understand the motions, forces and pressures generated by waves on boats with high-speed planing hulls. Planing hulls are like those used on a speedboat -- they're designed to produce lift and allow the watercraft to glide on top of the water, skimming more quickly over its surface. At higher speeds, 'wave slam' become a problem.

Algae industry to organize to capitalize on growing business opportunities
While Mainers have been harvesting seaweed for nearly 80 years for a variety of uses and products, in recent years wild harvests have not been able to meet market demand for some species. The Maine Technology Institute stepped in to provide $50,000 to help form a Maine algal cluster that would include those involved in macroalgae and microalgae to help the industry take advantage of a growing market.

Scientists use unmanned aerial vehicle to study gray whales from above
NOAA Fisheries scientists are using an unmanned aerial vehicle to take very precise overhead images of migrating gray whale mothers and calves. 'We can't put a gray whale on a scale, but we can use aerial images to analyze their body condition -- basically, how fat or skinny they are,' said NOAA Fisheries scientist John Durban. This research will help scientists understand how environmental conditions control the reproductive success of individual whales and ultimately of the population.

Quasi-sexual gene transfer drives genetic diversity of hot spring bacteria
New work from a multidisciplinary team of scientists used massive DNA sequencing of bacterial populations that grow in the hot springs in Yellowstone National Park to determine their genetic diversity and explore the underlying evolutionary dynamics. They found an unexpectedly high degree of sharing and exchange of genetic material between the tiny, green, photosynthetic cyanobacteria Synechococcus, which are abundant in these scalding, inhospitable environments.
