New research from the University of Washington and the Pacific Northwest National Laboratory links the brightness of clouds in the sky to airbone gasses produced by plankton all the way down on the ocean floor. Read about their research published in Science Advances on EurekAlert!.

Hitchhiking to Caribbean coral
Recently-introduced algae in Caribbean offers short-term benefits but could have serious long-term negative effects. New evidence shows it likely arrived via cargo ships from the Pacific.

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.

Little-known quake, tsunami hazards lurk offshore of Southern California
While their attention may be inland on the San Andreas Fault, residents of coastal Southern California could be surprised by very large earthquakes -- and even tsunamis -- from several major faults that lie offshore, a new study finds.

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.
