|Protected waters foster resurgence of West Coast rockfish|
West Coast rockfish species in deep collapse only 20 years ago have multiplied rapidly in large marine protected areas off Southern California, likely seeding surrounding waters with enough offspring to offer promise of renewed fishing, a new study has found.

Wave Glider surfs across stormy Drake Passage in Antarctica
A hardy ocean drone made a first-ever attempt to surf across Antarctica's stormy Drake Passage gathering data about ocean mixing.

Atmospheric effects of Arctic snowmelt
Researchers are exploring the changing chemistry of the Arctic's atmosphere to help answer the question of what happens as snow and ice begin to melt.

End-of-summer Arctic sea ice extent is eighth lowest on record
Arctic sea ice appeared to have reached its yearly lowest extent on Sept. 13, scientists have reported. Analysis of satellite data showed that at 1.79 million square miles (4.64 million square kilometers), this year's Arctic sea ice minimum extent is the eighth lowest in the consistent long-term satellite record, which began in 1978.

'King Tide' mapping project
'Dress rehearsal' will help quantify local flooding risk and validate storm-surge models, while laying groundwork for a long-term network of volunteer data collectors.

People's love of the seas could be the key for plastic pollution solution
Tapping into the public's passion for the ocean could be the key to reducing the threats to it posed by plastic pollution.

Black Sea water temperatures may buck global trend
Scientists have successfully simulated the Black Sea’s long term currents, salt water content and temperature for the first time.

Arctic sea ice once again shows considerable melting
This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, scientists have determined.

Old fish few and far between under fishing pressure
A new study has found that, for dozens of fish populations around the globe, old fish are greatly depleted -- mainly because of fishing pressure. Old fish are increasingly missing in many populations around the world.

Cost of not adapting to climate change would be at least five times higher
A study on damage to coastal considered only real estate loss. If nothing is done, researchers say, losses might be up to ten times higher if the predicament includes the spreading of flood- and global warming -related diseases.

Forest fires are not limited to hot or temperate climates
Evidence of wildfires dating back 20,000 years was recently discovered in the Massif du Queyras, in the heart of the French Alps, 2,240 meters above sea level. This discovery echoes the recent wildfires in the Arctic tundra, where the presence of trees have become increasingly common.

Ancient tree reveals cause of spike in Arctic temperature
A kauri tree trapped in a New Zealand swamp for 30,000 years may have overturned the idea that a slowdown in ocean currents in the North Atlantic may be entirely responsible for Dansgaard-Oeschger events and the characteristic bi-polar see-saw, which sees the Antarctica cool while the Arctic warms during glacial periods. The research reveals a mechanism that generates a 20,000 km long atmospheric bridge, reaching from Antarctica to the Arctic.

How openings in Antarctic sea ice affect worldwide climate
In a new analysis of climate models, researchers reveal the significant global effects that seemingly anomalous polynyas, or openings in sea ice, can have. Their findings indicate that heat escaping from the ocean through these openings impacts sea and atmospheric temperatures and wind patterns around the globe and even rainfall around the tropics.

USA threatened by more frequent flooding
The East Coast of the United States is threatened by more frequent flooding in the future. According to this study, the states of Virginia, North Carolina, and South Carolina are most at risk. Their coastal regions are being immersed by up to three millimeters per year -- among other things, due to human intervention.

Ship exhaust makes oceanic thunderstorms more intense
Thunderstorms directly above two of the world's busiest shipping lanes are significantly more powerful than storms in areas of the ocean where ships don't travel, according to new research.

Direct evidence of sea level 'fingerprints' discovered
The first observation of sea level 'fingerprints' -- tell-tale differences in sea level rise around the world in response to changes in continental water and ice sheet mass -- has been reported by researchers.

Increasing effective decision-making for coastal marine ecosystems
Marine restoration, rather than protection, might be the most cost-effective solution for coastal marine ecosystems suffering from human activities, a new study has found. The study examined how to best benefit coastal marine ecosystems on limited conservation budgets, to help managers better understand the trade-offs.

Unraveling a major cause of sea ice retreat in the Arctic Ocean
Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.

Longer, stronger summers in the Gulf of Maine
Summer in the Gulf of Maine is as much as two months longer and warmer than it has ever been before, according to a new study. The study examined the seasonality of sea surface temperature trends along the northeast coast of the United States.

Warmer world may bring more local, less global, temperature variability
Many tropical or subtropical regions could see increases in naturally occurring temperature variability as Earth warms over coming decades, a new study suggests. These local changes could occur even though Earth's global mean surface temperature variability will likely decrease because of less solar reflection from icecaps at high latitudes.
