Hidden values of open ocean
A team of scientists has for the first time attached a dollar value to several of the leading 'ecosystem services' -- or natural benefits -- provided by the Eastern Tropical Pacific Ocean, an immense region stretching west from the west coasts of North and South America.

Ocean forecast offers seasonal outlook for Pacific Northwest waters
A new study evaluates the skill of a seasonal forecast for predicting future conditions in the Pacific Northwest marine environment.

94 million-year-old climate change event holds clues for future
A major climate event millions of years ago that caused substantial change to the ocean’s ecological systems may hold clues as to how the Earth will respond to future climate change, a researcher said.

Caribbean Sea acts like a whistle and can be 'heard' from space
A study of the Caribbean Sea has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from space in the form of oscillations of the Earth's gravity field.

Understanding rogue ocean waves may be simple after all
An international team of scientists has developed a relatively simple mathematical explanation for the rogue ocean waves that can develop seemingly out of nowhere to sink ships and overwhelm oil platforms with walls of water as much as 25 meters high.

Coral reefs facing a hot time and increased bleaching, especially along US coasts
A new NOAA outlook shows that many coral reefs across around the world will likely be exposed to higher-than-normal sea temperatures for an unprecedented third year in a row, leading to increased bleaching - and with no signs of stopping. While the bleaching event is global, it will hit the US hard.

Breathing space for the Gulf Stream
The salinity of the waters around Greenland plays an important role in driving the Gulf Stream. There are concerns that a freshening by the increasing ice losses from the Greenland ice sheet could weaken the current system. New model calculations conducted by an international research team suggest, however, that a large fraction of this meltwater is removed from the most sensitive areas by boundary currents, delaying the influence on the Gulf Stream.

Marine debris on the shores of an isolated tropical atoll in the Indian Ocean
The huge volumes of litter we leave in the oceans is one of the greatest environmental problems of our time. Scientists have studied how the beaches on a remote atoll in the Indian Ocean have been covered with litter, even though the atoll has no permanent residents.

Life as we know it most likely arose via 'long, slow dance'
The first eukaryote is thought to have arisen when simpler archaea and bacteria joined forces. But researchers now propose that new genomic evidence derived from a deep-sea vent on the ocean floor suggests that the molecular machinery essential to eukaryotic life was probably borrowed, little by little over time, from those simpler ancestors.

Researchers release 'Frankenturtles' into Chesapeake Bay
Researchers are working to reduce sea turtle mortality by trying to pinpoint where the hundreds of dead loggerhead sea turtles that wash up on Chesapeake Bay beaches each summer may have succumbed. They are doing so by tracking the path of made-in-the-lab 'Frankenturtles' as winds and currents disperse them from a mid-Bay release site.

El Nino drives fastest annual increase on record of carbon dioxide
The rising concentration of atmospheric carbon dioxide has passed a symbolic threshold early due to the fastest annual increase on record, report scientists.

Earth scientists push boundaries of 3D modeling
Earth scientists are changing the way they study the geological record, thanks to new advances in three-dimensional modeling. This work will have major implications for the study of geomorphology, geodynamics and climate, say authors.

El Nino made a nuisance of itself in 2015
The frequency of nuisance tidal flooding in many U.S. cities increased as predicted for the 2015 meteorological year, from May 2015 to April 2016, according to a new report.

Average 'dead zone' predicted for Gulf of Mexico in 2016
Scientists forecast that this year's Gulf of Mexico dead zone -- an area of low to no oxygen that can kill fish and marine life -- will be approximately 5,898 square miles or about the size of Connecticut, the same range as it has averaged over the last several years.

On land and at sea, large animals are in 'double jeopardy'
Large animals hunted for their parts -- such as elephant ivory and shark fins -- are in double jeopardy of extinction due to their large body size and high value, according to a new analysis. The study reveals underappreciated risk to marine species similar to that of iconic terrestrial species, but elevated by key differences in the sea.

Greenland's 2015 melt records consistent with 'Arctic amplification'
Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study provides the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Artic amplification.

Fishing prohibitions produce more sharks along with problems for fishing communities
Scientists have good news about fishing closures established in Indonesia's shark sanctuary, which are good for sharks and other fish. The bad news: People who rely on shark fishing for their livelihoods have few other options but to fish in unprotected areas and sometimes turning to illegal practices.

Danger from extreme storms, high seas to rise, warn Australian researchers
Storms that battered Australia's east coast are a harbinger of things to come and a stark reminder of the need for a national effort to monitor the growing threat from climate change, coastal researchers warn.

In a three-year effort to understand the effects of known stressors such as overfishing and nutrient pollution on coral reefs, scientists made a totally unexpected finding: A normally healthy interaction between fish and coral had turned deadly. The new work also shows how rising ocean temperatures are potentially lethal for coral reefs.
