While the study is unlikely to settle the scientific debate it does support the idea that Earth's global warming continues in the ocean even
whether ocean heat storage is responsible for the hiatus versus not enough heat reaching the surface of the Earth said study co-author Ka-Kit Tung of the University of Washington in Seattle.
Earth's Tallest Mountain to Deepest Ocean Trench Global storage closet Scientists have blamed the oceans for the global warming pause before
However in seeking to test this idea with temperature data oceanographer Xianyao Chen of the Ocean University of China in Qingdao
Tung and Chen then searched ocean by ocean until they hit on the North Atlantic where the heat was playing hooky The pair primarily relied on Argo floats which record ocean temperature
Unfortunately the massive array of ocean temperature measurements by Argo floats has only been made after the early 2000s just
So being conclusive about each ocean basin is limited by data availability. Tung and Chen noticed that the North Atlantic's heat content (a measure of stored energy) shifted in 1999 about
The ocean started absorbing heat at depths below 984 feet (300 m).(The South Atlantic ocean also took up some heat.
These regions stored more heat energy than the rest of the world's oceans combined even the enormous Pacific ocean the researchers'temperature data show.
The AMOC is part of a worldwide ocean conveyor belt. Here's how the AMOC works: In the North Atlantic salty tropical water flowing north cools off and sinks.
When the water sinks it traps heat in the ocean depths. Ocean surface temperatures drive the current:
fast when cold slow when warm. Images: The World's Biggest Oceans and Seas Between 1945 and 1975 the cycle was in a cool phase sucking up atmospheric heat at a rapid pace.
Toward the end of this cycle in the 1970s scientists noticed a suspected global cooling that was touted as the beginning of a possible Ice age.
Finally in 1999 the current switched back to a cold speedy plunge into the ocean depths taking extra heat along with it.
I still think the Pacific ocean is playing the lead role in this ocean heat uptake but this study is important as it points to an additional role from the Atlantic
and Southern Oceans said England who co-authored the Aug 3 Nature Climate Change study. Email Becky Oskin or follow her@beckyoskin. Follow us@livescience Facebook & Google+.
Rapid erosion of these mountains contributed large amounts of sediment to lowlands and shallow ocean basins.
Sea levels were high with much of western North america under water. Climate of the continental interior regions was very warm during the Devonian period and generally quite dry.
The Devonian period was a time of extensive reef building in the shallow water that surrounded each continent and separated Gondwana from Euramerica.
Reef ecosystems contained numerous brachiopods still numerous trilobites tabulate and horn corals. Placoderms (the armored fishes) underwent wide diversification

The collapse refers to an unstoppable self-sustaining retreat that would drop millions of tons of ice into the sea.
However the race to the sea is happening at different rates. Recently the fast-flowing Pine Island Glacier stabilized slowing down starting in 2009.
The slowdown was only at the ice shelf where the glacier meets the sea. Further inland the glacier is still accelerating.
To see Thwaites this monster glacier start accelerating in 2006 means we could see even more change in the near future that could affect sea level Mouginot said.
Pine Island Glacier's acceleration reached up to 155 miles (230 km) inland from where it meets the ocean.
Mouginot said warmer ocean waters contributed to the speed up. The huge ice streams flowing from West Antarctica are held back by floating ice shelves that act like dams.
Several recent studies have suggested that warmer ocean water near Antarctica is melting and thinning these ice shelves from below.

#'Mummy Lake'Used for Ancient Rituals, Not Water Storage In Colorado's Mesa verde national park a large 1000-year-old structure long thought to be an Ancestral Puebloan water reservoir may not have been built to store water after all a new study suggests.
Instead the so-called Mummy Lake which isn't a lake and has never been associated with mummies likely held ancient ritual ceremonies researchers say.
Mummy Lake is lined a sandstone circular pit that was originally 90 feet (27.5 meters) across
Several subsequent studies of Mummy Lake have supported also this view leading the National parks Service to officially name the structure Far View Reservoir in 2006.
Far View refers to the group of archaeological structures located on the northern part of the park's Chapin Mesa ridge where Mummy Lake is situated also.
In the new study researchers analyzed the hydrologic topographic climatic and sedimentary features of Mummy Lake and the surrounding cliff area.
See Images of Mummy Lake in Mesa verde The fundamental problem with Mummy Lake is that it's on a ridge said study lead author Larry Benson an emeritus research scientist for the U s. Geological Survey and adjunct curator
Mummy Lake and other buildings. Previously scientists had thought Mummy Lake the northernmost structure#was a key part of a large water collection
and distribution system that transported water between these structures to areas south of the reservoir.
They proposed that a gathering basin was located once uphill from Mummy Lake and that a hypothetical feeder ditch connected the two locations.
Studies have shown that another shallow foot-paved ditch runs south from Mummy Lake to Far View House
Lake Natron Gives Up Its Dead The prevailing idea was that precipitation would first collect in the basin
and then travel down to Mummy Lake along the ditch; from there some of it could then travel to the rest of the village providing water for drinking
I think it's appealing to think of Mummy Lake as a reservoir Benson told Live Science noting that the Ancestral Puebloans of Mesa verde lived in a region without any natural bodies of water.
They found that the ditches leading from Mummy Lake to the southern structures couldn't have functioned as water canals or irrigation distribution systems.
Next the team used climate models to investigate Mummy Lake's potential to store water.
if a hypothetical feeder ditch could actually provide Mummy Lake with water. The engineering and sediment transport work showed that any water in the ditch would start moving so much dirt that it would block the path Benson said.
That is soil would have clogged quickly the ditch after regular rainfall preventing the water from reaching Mummy Lake.
Benson and his colleagues propose Mummy Lake is unroofed an ceremonial structure not unlike the ancient kivas and plazas elsewhere in the Southwest.
Furthermore the ditches connecting Mummy Lake to Far View Village Spruce Tree house and Cliff Palace aren't canals to transport water
Benson and his colleagues suspect the same thing happened at Mesa verde. Mummy Lake was built as early as A d. 900 around the same time as the rest of the Far View group of structures;
We could probably call it'Mummy Lake'again. The study was detailed in the April issue of the Journal of Archaeological Science.

Sodium traces hint at subsurface ocean on Enceladus: Nature Newsthe water plumes erupting from the south pole of Saturn's moon Enceladus could be caused by a liquid ocean lurking many kilometres underground rather than by geysers erupting from a salty ocean just beneath the moon

because liquid water elsewhere in our solar system is the most promising place to look for signs of life.
if it had verified the near-surface ocean geyser theory. An alternative explanation is that a salty liquid ocean exists deep underground
and is evaporating releasing pure water as a jet of steam and leaving the salty residue behind.
Frank Postberg at the Max Planck Institute for Nuclear physics in Heidelberg, Germany, likes the ocean idea.
if there is a liquid ocean close to Enceladus's mineral-rich rocky core, deep beneath the thick icy crust, says Postberg.
Postberg says the vapour evaporating from the ocean will also contain other gases, and bubbles of those gases carry salty water droplets through vents in Enceladus's crust, to be frozen suddenly once they get there.
Salt-rich grains are frozen directly ocean water dragged up by strong vapour flow says Postberg.
But other models exist to explain Enceladus's plumes apart from oceans or geysers. One of these suggests that reservoirs of clathrates gassy molecules locked up in the lattice of another molecule exist below the surface.
Sodium isn't the proof of a liquid ocean, she says. Sodium can be locked up in the ice of an icy clathrate model.
