Pacific’s big drop in oxygen blamed on pollution from Asia
For decades, air pollution drifting from East Asia out over the world’s largest ocean has kicked off a chain reaction that contributed to oxygen levels falling in tropical waters thousands of miles...
View Article‘Dirty blizzard’ carried Deepwater oil to the seafloor
A new study offers a clearer picture of the hidden effects of the 2010 Deepwater Horizon disaster—the largest marine oil spill in US history. While oil was undetectable in surface waters a few weeks...
View ArticleSurvey of 6,000 coral reefs uncovers 15 ‘bright spots’
Researchers have discovered a handful of “bright spots” among the world’s embattled coral reefs, suggesting that a radical new approach to conservation may have promise. In one of the largest global...
View ArticleMussel shells aren’t as thick as they used to be
The shells of California mussels collected from the Pacific Ocean in the 1970s are on average 32 percent thicker than those of modern specimens, research shows. Shells collected by Native Americans...
View ArticleWhy Pluto may have an ocean under its icy shell
When the NASA’s New Horizons spacecraft buzzed by Pluto last year, it revealed tantalizing clues that the dwarf planet might have—or had at one time—a liquid ocean sloshing around under its icy crust....
View ArticleHow a ‘bad day at the ocean’ creates rogue waves
Rogue ocean waves can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high. Now, scientists have developed a relatively simple...
View ArticleAcidic oceans make it hard for snails to escape predators
Ocean acidification makes it harder for sea snails to escape from their sea star predators. The findings suggest that by disturbing predator-prey interactions, ocean acidification could have ongoing...
View ArticleZooplankton warn us: Extinction has a tipping point
Experts say the results of a study of ancient zooplankton fossils offer a warning about mass extinction events: There’s a tipping point, at which dramatic declines in populations begin. The researchers...
View ArticlePatchy oxygen in ocean may have stalled evolution
Evolution has slowed to a crawl a few times in four billion years. And an eon or so has passed before more complex life forms, such as simple animals, could arise. Evolution may have been waiting for a...
View ArticleHow salt and temperature ‘herd’ phytoplankton
Subtle and brief differences in ocean salinity or temperature work like physical barriers for phytoplankton, and result in a patchy distribution of the oceans’ most important food resource....
View ArticleCoral larvae wouldn’t survive vast ocean trek
Contrary to a prevailing theory, coral larvae could not survive the 3,100-mile (5,000-km) trip across the Pacific Ocean to replenish endangered corals in the eastern Pacific, according to new research....
View ArticlePacific sea level predicts rise in surface temps
Sea level changes in the Pacific Ocean let scientists estimate future global average surface temperatures, a new report shows. Based on the Pacific Ocean’s sea level in 2015, geoscientists estimate by...
View ArticleIs melting ice lowering the salinity of the Southern Ocean?
Over the past decades, the northward drift of sea ice surrounding Antarctica has strengthened. This not only has increased the extent of the sea ice, but also has freshened the sea water around the...
View ArticleBiggest ocean animals are ‘poised to disappear’
An unprecedented pattern of extinction in the oceans today that largely targets large-bodied animals over smaller creatures is likely driven by human fishing, a new study suggests. “We’ve found that...
View ArticleCool waves from open ocean protect coral reefs
As oceans warm, physical forces like wave strength and water flow influence which coral reefs thrive and which die, research shows. The results, published in a report in the journal Limnology and...
View ArticleTeam estimates size of Pluto’s hidden ocean
There’s growing evidence Pluto has an ocean hiding under its icy shell. Now scientists are estimating how thick that liquid layer might be. They say it’s likely there’s more than 100 kilometers of...
View ArticleToxic algal bloom tied to Pacific’s warm ‘blob’
The unprecedented West Coast toxic algal bloom of 2015 appears to be linked to the unusually warm ocean conditions—nicknamed “the blob”—in the winter and spring of that year. The bloom closed fisheries...
View ArticleDeepwater Horizon spill hit where tuna spawn
The Deepwater Horizon oil spill was one of the largest environmental disasters in history, releasing roughly 4 million barrels of crude oil into the Gulf of Mexico. For Atlantic bluefin tuna, it...
View ArticleLobsters grow larger in protected Scottish bay
The first and only protected marine reserve in Scotland shows promise for marine conservation, say researchers. Adult lobsters there more than doubled in number and increased in size. Conducting...
View ArticleFish adapts to hotter water but would rather move
Coral reef fish, which struggle to adapt to warmer ocean temperatures brought about by global climate change, may instead opt to relocate to cooler parts of the ocean. “When fish have to adapt to...
