into the ocean basins.
Warming temperatures causes ocean water to expand, which raises sea level and glacial ice to melt that creates water that makes its way
into ocean basins.
Not exact matches
They are derived from the idea that if the ice buttress for one of these big
basins in East Antarctica were to go, you might get lots of ice sliding
into the
ocean very quickly, then sea level stabilizing after that most unbalanced ice is released.

basin into the single largest polluter of the Pacific
Ocean.
Using supercomputers, the researchers found that this dense piece of
ocean floor material (called a lithospheric slab) is slowly sinking
into the Earth's mantle and is responsible for the formation of the Lake Eyre Basin, one of the Earth's largest internally drained
basins and home to the lowest point in Australia at 15m below sea level, as well as the Murray - Darling Basin, home to the largest river system in Australia.
For scientific purposes, the Antarctic ice sheet is often divided
into catchment
basins so that comparative measurements can be taken to work out how the ice in each
basin is changing and discharging ice to the
oceans.
Along one string of sites, or «stations,» that stretches from Antarctica to the southern Indian
Ocean, researchers have tracked the conditions of AABW — a layer of profoundly cold water less than 0 °C (it stays liquid because of its salt content, or salinity) that moves through the abyssal ocean, mixing with warmer waters as it circulates around the globe in the Southern Ocean and northward into all three of the major ocean ba

into the opening of a nascent

Dr. Kevin Trenberth and his team have made a unique contribution through the investigation of climate variability and trends in the past, and through the use of models and other creative efforts to reconstruct river discharge
into the
oceans across the planet for almost 1000 river
basins.
Here's a hint though: Earth's rotation, and the division of the
ocean into basins by the continental land mass configuration, play a large role in Ekman pumping and suction.
The massive water system is thought to stretch for 3,700 miles across the Amazon
basin with an average width of about 200 miles, flowing west to east
into the Atlantic
Ocean at a rate of 350 feet a year.
So the challenge is to try to resolve that evidence with the
ocean heat data that shows that the energy is going
into other
ocean basins.
All one needs to do is divide the global
oceans into tropical and extratropical subsets per
ocean basin.
Whether the
ocean surface warms more than that is totally dependent on how long it takes excess surface layer energy to be diluted
into the entire
basin.
Even scientists like Gavin Schmidt and Judith Curry were almost as quick as me to recognize that
ocean surface warming, once diluted
into the much larger
basin, can never again spontaneously concentrate in the surface layer.
Any precipitation or glacial meltwater flowing
into an endorheic
basin could require centuries to thousands of years to flow back to the
oceans.
ii) The 60 year PDO Oscillation appears to be internal to the
ocean system as the initial ENSO effects carry
into the other
ocean basins and then feed back to the Pacific by way of what you call a stadium wave but which I previously called he net interaction between the various
ocean oscillations.
The resulting Common Water, also called Antarctic Circumpolar water, flows northward at depth
into the three
ocean basins (primarily the Pacific and Indian
Oceans).
Two reasons why this should be so in the real world are that, first, the Southern Hemisphere subtropical gyres are situated mostly in the Southern
Ocean and South Atlantic, and second, that some of the heat coming
into the Pacific
Ocean basin doesn't actually stay there.
In the northern hemisphere the land masses prevent this and the
ocean circulation is broken
into smaller gyres in the Atlantic and Pacific
basins.
Most of the deep
ocean warming is occurring in the subtropical
ocean gyres - vast rotating masses of water in each
ocean basin where near - surface currents converge and are forced downward
into the
ocean interior.
Trade winds transport some of this water vapor out of the Atlantic
Ocean basin, across the Isthmus of Panama, and
into the Pacific
Ocean basin.
We show that the influx of water
into the volume created by this subsidence produces a sea - level fall at locations distant from these margins — indeed over the major
ocean basins — that is comparable in amplitude to the syphoning mechanism isolated by Mitrovica and Peltier (1991).»
Since the East Indian and West Pacific
Oceans are not isolated by landmass,
ocean currents spread this cumulative warming
into the adjoining
ocean basins.
The recent papers looking at
ocean ingress
into the
basin is also a worry when we look at the SST's of those waters in Fram and Bering.
And study authors found that 2 C to 5 C warming of local
ocean waters with somewhat greater local air temperature increases was capable of flooding these basins in stages — forcing Totten's glacial ice to flow out into the Southern Ocean and provide significant contributions to sea level

I have illustrated and document that there are multiyear aftereffects of ENSO events that cause the positive trends in SST and TLT anomalies outside of the tropical Pacific, and I have shown that the rise in global OHC, when broken down
into logical
ocean basin subsets, is dominated by natural variables.
These and other observations can be integrated
into a model with feedbacks and having two unstable end ‐ points that is consistent both with classical studies of past climate states, and also with recent analysis of ice dynamics in the Arctic
basin by Zhakarov, whose oscillatory model identifies feedback mechanisms in atmosphere and
ocean, both positive and negative, that interact in such a manner as to prevent long ‐ term trends in either ice ‐ loss or ice ‐ gain on the Arctic Ocean to proceed to an ultimate s

The western part of the Tethys evolved
into the Mediterranean Sea not long after it had been cut off from the global
ocean system about 6 million to 5 million years ago and had formed evaporite deposits which reach up to several kilometres in thickness in a land - locked
basin that may have resembled Death Valley in present - day California.
Runoff is collected over geographically realistic river
basins and mixed
into the

If an «ice plug» near the coast of Wilkes

«Third, in a period when
ocean basins were similar to modern, ice age climate sensitivity to pCO2 changes is underestimated by climate models even when long term changes in solar forcing and ice sheet size and distribution are taken
into account, implying that internal positive feedbacks are stronger than previously thought.»
Freshening of the Arctic is so intense (McPhee et al. 2009) that the Arctic

These experiments provide new insight
into mechanisms of past climate changes on Earth, which have been driven in part by tectonic changes in
ocean basins and consequent changes in
ocean circulation and heat transport.
You can just plug a huge pneumatic hose
into the nearest volcano and inflate the earth with CO2, and that way the
ocean basins would increase in area and volume, and the sea level would fall again.
