Scientists triple known types of viruses in world’s oceans
Researchers report they've tripled the known types of viruses living in waters around the globe, and now have a better idea what role they play in nature. The discovery could influence carbon reduction efforts.

Antarctic mystery solved?
Tiny ocean fossils distributed widely across rock surfaces in the Transantarctic Mountains point to the potential for a substantial rise in global sea levels under conditions of continued global warming, according to a new study. The study indicates the massive East Antarctic Ice Sheet (EAIS) has a history of instability during ancient warm periods and could be vulnerable to significant retreat and partial collapse induced by future climate change.

Hurricanes, storm surges and icebergs: How warmer seas are changing our planet
Severe hurricanes, storm surges and an increase in the number of icebergs are just some of the changes planet Earth has experienced due to warming oceans over the last 20 years, according to a new report.

The difficulty of predicting an ice-free Arctic
The Arctic is nearing its seasonal sea ice minimum this month, but predicting exactly when the region will see its first ice-free summer may be more difficult than previously believed, according to the results of new research.

Heatwaves in the ocean: Risk to ecosystems?
Marine ecosystems are responsible for about half of global annual primary production and more than one billion people rely on fish as their primary protein source. Latest studies show that enormous warm water bubbles in the ocean are having a noticeable impact on ecosystems. How should we interpret these changes?

How wave dynamics and water flows affect coral reefs
While climate change threatens coral reefs in oceans around the world, not all reefs are affected equally. As oceans warm, physical forces like wave strength and water flow influence which reefs thrive and which die, according to a study. The results offer new insight into how climate change will affect reefs on a local level -- and also hint at steps conservationists can take to reduce the impact of warming on these fragile ecosystems.

2016 ties with 2007 for second lowest Arctic sea ice minimum
The Arctic's ice cover appears to have reached its minimum extent on September 10, 2016, according to scientists. Arctic sea ice extent on that day stood at 4.14 million square kilometers (1.60 million square miles), statistically tied at second lowest in the satellite record with the 2007 minimum.

First U.S. marine national monument created in Atlantic
Deep in the oceans exist some of the world's oldest and most mysterious sea canyons and mountains, or seamounts. Formed millions of years ago by extinct volcanoes and sediment erosion, sea canyons and seamounts are biodiversity hot spots -- home to many rare and endangered species.

'Funneling' behind severe flooding on the Clyde
A “funneling” effect has been a major factor in severe flooding on the River Clyde in recent years, according to a study by English mathematicians.

Taking a fault's temperature
Ever think about taking a fault's temperature? What would you learn? A unique experiment where temperature was continuously measured for nearly a year inside the fault that made the catastrophic 2011 magnitude 9.0 Japan Earthquake reveals the thermal signature of pulses of water squirting out of fractures in response to other earthquakes on neighboring faults.

Larger marine animals at higher risk of extinction, and humans are to blame
In today's oceans, larger-bodied marine animals are more likely to become extinct than smaller creatures, according to a new report. It's a pattern that is unprecedented in the history of life on Earth, and one that is likely driven by human fishing.

Whales might be hidden, but these new buoys can help find them
How do you find whales that dive so deep and spend so little time at the surface that some species have never been observed alive? Sometimes you just have to listen closely.

All polar bears across the Arctic face shorter sea ice season
A new study finds a trend toward earlier sea ice melt in the spring and later ice growth in the fall across all 19 polar bear populations, which can negatively impact the feeding and breeding capabilities of the bears. The paper is the first to quantify the sea ice changes in each polar bear subpopulation across the entire Arctic region using metrics that are specifically relevant to polar bear biology.

New insights into the impacts of ocean acidification
A new study offers clues to the potential impact of ocean acidification deep-sea, shell-forming organisms. Increasing atmospheric carbon dioxide (CO2) is also increasing oceanic CO2. Ocean acidification is therefore one of the most important research areas regarding the effects of elevated CO2 on deep-sea marine calcifiers and the marine ecosystem in general, say the researchers.

Coastal occupation affects tropical reefs in Brazil
Researchers in Brazil warn of the negative environmental impacts of unplanned coastal occupation on tropical reefs and consequently on the conservation of marine biodiversity. Researchers state that this process has already taken place in Western Mediterranean.

After a strong El Nino winter, NASA model sees return to normal
Not too hot, not too cold -- instead, water temperatures in the equatorial Pacific Ocean should be just around normal for the rest of 2016.
