But there's little shipping in the Southern Ocean and Doney said that's a region of high concern.
We used to think energy from the breakdown of chemicals was only substantial in dark places where photosynthesis is impossible like deep oceans.

#Major increase in West Antarctic glacial losssix massive glaciers in West Antarctica are moving faster than they did 40 years ago causing more ice to discharge into the ocean and global sea level to rise according to new research.
--which has a significant impact on sea level rise he said. The researchers studied the Pine Island Thwaites Haynes Smith Pope and Kohler glaciers all of
which discharge ice into a vast bay known as the Amundsen Sea Embayment in West Antarctica.
If melted completely the glaciers'disappearance would raise sea levels another 1. 2 meters (four feet) according to co-author and UC-Irvine Professor Eric Rignot.
The decades of increasing speeds and ice loss are a strong indication of a major long-term leakage of ice into the ocean from that sector of Antarctica noted Rignot.
This region is considered the potential leak point for Antarctica because of the low seabed. The only thing holding it in is said the ice shelf Robert Thomas a glaciologist at the NASA Wallops Flight Facility in Wallops Island Va. who was involved not in the study.
Ice shelves are platforms of permanent floating ice that form where glaciers meet the sea.
In West Antarctica ice shelves prevent the glaciers investigated in the study from slipping more rapidly into the ocean.
Smith and Pope Glaciers nearly tripled the amount of ice they drained into the ocean since 1973.
The research team also found that the Pine Island Glacier is accelerating along its entire drainage system--up to 230 kilometers (155 miles) inland from where it meets the ocean.

because it drowned beneath the Bering sea when sea levels rose. University of Utah anthropologist Dennis O'Rourke and two colleagues make that argument in the Friday Feb 28 issue of the journal Science.
A Frozen Isolated Dawn for the Earliest Americansduring the last glacial maximum thick glacial ice sheets extended south into what now is the northern United states sea levels dropped some 400 feet O'Rourke says.
As the glaciers melted sea levels began to rise reaching current levels 6000 years ago. During the long glacial period Siberia and Alaska were linked by the Bering land bridge
The idea that rising sea levels covered evidence of human migration to The americas has long been cited by researchers studying how early Native americans moved south along the Pacific coast as the glaciers receded and sea levels rose.
Although most such sites are underwater some evidence of human habitation in shrub tundra might remain above sea level in low-lying portions of Alaska and eastern Chukotka (in Russia.

Further the products of these reactions are transported to the oceans in rivers where they ultimately form carbonate rocks like limestone that lock away carbon on the seafloor for millions of years preventing it from forming carbon dioxide in the atmosphere.
Researchers found that non-nitrogen fixing trees become more abundant closer to sea replacing the usually more abundant nitrogen fixing trees in these deserts.
Nutrients are limiting in the desert so this input from the sea through the nitrogen-rich guano has a positive effect for trees that cannot fix nitrogen.
What we found very striking is that trees that do fix nitrogen from the air do not seem to benefit from nutrients coming from the sea
#Oceans hidden waves show their power: Origins of giant underwater waves explainedlarge-scale tests in the lab and the South china sea reveal the origins of underwater waves that can tower hundreds of feet.
Their effect on the surface of the ocean is negligible producing a rise of just inches that is virtually imperceptible on a turbulent sea.
But internal waves which are hidden entirely within the ocean can tower hundreds of feet with profound effects On earth's climate and on ocean ecosystems.
Now new research both in the ocean and in the largest-ever laboratory experiments to investigate internal waves has solved a longstanding mystery about exactly how the largest known internal waves in the South china sea are produced.
or salinity differences that cause ocean water to become stratified. Though invisible to the eye the boundary between colder saltier water below and warmer less-salty water above can be detected instrumentally.
That boundary layer can resemble the ocean's surface producing waves that reach towering heights travel vast distances
and can play a key role in the mixing of ocean waters helping drive warm surface waters downward
Because these internal waves are hard to detect it is often a challenge to study them directly in the ocean.
These are the most powerful internal waves discovered thus far in the ocean Peacock says. These are skyscraper-scale waves.
They are the lumbering giants of the ocean Peacock says. The team's large-scale laboratory experiments on the generation of such waves used a detailed topographic model of the Luzon Strait's seafloor mounted in a 50-foot-diameter rotating tank in Grenoble France
In the years since scientists have come to a greater appreciation of the significance of these giant waves in the mixing of ocean water--and therefore in global climate.
These waves are potentially the key mechanism for transferring heat from the upper ocean to the depths Peacock says so the focus of the research was to determine exactly how the largest of these waves as revealed through satellite imagery of the Luzon Strait region are generated.
The existence of internal waves in oceans has been known for well over a century Peacock says but they have remained poorly understood because of the difficulty of observations Among the new techniques that have helped to propel the field forward is the use of satellite data:
Internal waves can bring nutrients up from ocean depths Peacock says. Matthew Alford an associate professor of oceanography at the University of Washington who was involved in the related field studies for this project says The strong forcing
and ridge geometry at Luzon Strait result in some of the strongest internal waves in the world's oceans.

and ocean variability than at first thought. Observations by a team of scientists at British Antarctic Survey and other institutions show large fluctuations in the ocean heat in Pine Island Bay.
The team discovered that oceanic melting of the ice shelf into which the glacier flows decreased by 50 per cent between 2010 and 2012
The acceleration is thought to be caused by thinning of the floating ice shelf created as the glacier slides into the sea.
and the glacier's response is key to assessing how much it will contribute to rising sea levels.
It's now known that much of the thinning is due to a deep oceanic inflow of Circumpolar Deep Water (CDW) on the continental shelf neighbouring the glacier.
But observations made in January 2012 and reported now in Science show that ocean melting of the glacier was the lowest ever recorded.
High resolution simulations of the ocean circulation in the ice shelf cavity demonstrate that the ridge blocks the deepest ocean waters from reaching the thickest ice.
In January 2012 the dramatic cooling of the ocean around the glacier is believed to be due to an increase in easterly winds caused by a strong La Nin㣠event in the tropical Pacific ocean.
The study stresses the importance of both local geology and climate variability in ocean melting in this region.
We found ocean melting of the glacier was the lowest ever recorded and less than half of that observed in 2010.
This enormous and unexpected variability contradicts the widespread view that a simple and steady ocean warming in the region is eroding the West Antarctic Ice Sheet.
It is not so much the ocean variability which is modest by comparison with many parts of the ocean
but the extreme sensitivity of the ice shelf to such modest changes in ocean properties that took us by surprise.
That sensitivity is a result of a submarine ridge beneath the ice shelf that was discovered only in 2009
when an Autonomous Underwater Vehicle mapped the seabed beneath the ice. These new insights suggest that the recent history of ice shelf melting

As the radiation moves from the forest to the ocean, it is important to set a baseline of knowledge to see how it affects humans and animals in the long run,
And it's also where the much of the ice streams drains out into the sea rather than collect on a large ice shelf.
That means that the ice will flow into the ocean at a faster rate, contributing even more to sea level rise.
Such an acceleration is of particular concern at the Pine Island Glacier, because, among Antarctic glaciers, it's the one that's contributing the most to sea level rise.
In fact, he said, ice flows from that glacier alone account for a quarter to a third of Antarctica's total contribution to sea level rise.
While both polar caps are losing ice as the world's climate warms the Pine Island glacier is melting at an alarming rate, about six meters a year, according to an ABC News report.
