Sentences with phrase «deep ocean storage»

The twilight zone plays a prominent role in transferring the atmosphere's excess carbon dioxide (from fossil fuel burning) into deep ocean storage.
It's probing the causes of variations in the Mauna Loa record, so it's really not getting to the issue of deep ocean storage as far as I can tell.
As shown in figure 4, Meehl et al's climate model simulations had the bulk of the ocean heat storage occurring in the Southern Ocean and the Pacific, but most deep ocean storage during IPO - equivalent decades was in the Atlantic and Southern Oceans.

Not exact matches

The high - decibel dispute between Shell and Greenpeace earlier this summer about the state of the deep ocean off western Scotland, where Shell wanted to dump the redundant oil storage rig, has set off a fascinating debate about the deep ocean.
The research also supports a theory that a parallel pause in air temperature rise in recent years may result from storage of heat in the deep ocean.
Additionally, the paper supports the theory that heat storage in the deep ocean may be partly responsible for the parallel pause in Earth's surface temperatures over the past 13 years.
While there are possibilities of storage in wells and deep in the ocean, stabilizing the atmospheric CO2 concentration would require gathering up the equivalent of 1 to 2 times the world's existing above ground vegetation and putting it down abandoned oil wells or deep in the ocean.
These results provide new insights into the role that the deep ocean plays as a storage reservoir for carbon, a process that helps to dampen the effects of human - driven climate change.
Deep ocean heat and carbon storage are dependent on heat transfers driven by mesoscale eddy mixing.

It seems to me that they must show deeper mixing than 50 M, since there is not enough mass in the upper 50 meters of ocean to account for the annual heat storage changes that are implied by observations for the the full integrated 700 meter volume of ocean.
The first place I would look would be energy storage in the deeper ocean basins.
Meehl et al., 2011 (doi: 10.1038 / NCLIMATE1229) show that with a similar radiative imbalance, hiatus periods and non-hiatus periods can occur, and that in the first case larger heat storage in the deep ocean takes place.
And another question, why is the hiatus period during the 1960s not reflected in a larger heat storage in the deep ocean?
There are several reasons for this; for example, aerosol emissions have risen, there has been a preponderance of La Niña events at the end of this timeframe, there has been increased heat storage in the deep oceans, and there was also an extended solar minimum.
Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).
Vast and slow to change temperature, the oceans have a huge capacity to sequester heat, especially the deep ocean, which is playing an increasingly large uptake and storage role.
The decadal mean planetary energy imbalance, 0.75 W / m2, includes heat storage in the deeper ocean and energy used to melt ice and warm the air and land.

Plus the deep ocean heat storage, then the cooling deep ocean and then the missing hot spot.
Physically, C1 can be thought of as representing the concentration of CO2 in long - term stores such as the deep ocean; C1 + C2 as representing the CO2 concentration in medium - term stores such as the thermocline and the long - term soil - carbon storage; and C = C1 + C2 + C3 as the concentration of CO2 in those sinks that are also in equilibrium with the atmosphere on time scales of a year or less, including the mixed layer, the atmosphere itself and rapid - response biospheric stores.
Long - term storage Natural and human emissions Deep ocean Fig. 20 - 6, p. 469
Note that the deep ocean plays a lesser role in heat storage or dissipation from short term forcings (e.g., volcanic eruptions), and so equilibrium in these cases can be nearly complete within decades — a major difference from persistent CO2 forcing.
This is particularly true for a long term response to CO2 forcing, because of the major role of the deep ocean (down to 4000 meters and even below) in long term heat storage needed for equilibrium.
I note what you say about deep ocean heat storage, although the amounts reported by Purkey & Johnson are not huge, have large error bounds and will to some extent already be accounted for in the standard 0 - 3000m ocean heat storage datasets.
In particular there could be significant heat storage changes deeper in the ocean that are inadequately monitored by the existing ocean network.
The latter determines the intensity of convection in the ocean and the timescale of deep - ocean processes affecting CO2 uptake and storage.
This will primarily come from storage in the deep ocean.
In addition, since we have already passed that level to over 400 ppm, and there is no storage seen that can affect us in the future more that 0.06 C (the actual deep ocean temperature rise), there is no long - term effect that happens independently of the level of CO2.
We have lots of data on the surface temperatures and now even the top 700m of water or so, but there is so much energy storage in the deeper oceans that we unfortunately don't know all that much about.
We've gotten better measurements of heat storage in the oceans since sometime in the 1990s (see Roger Pielke Sr.'s blog, lots of entries on this subject, search for «Josh Willis» to start), I think from satellites supplemented by unmanned devices which dive to as deep as 2,000 meters then resurface and send their data to satellite (Argo floats).
The deep ocean is a critical storage area for carbon, keeping it from re-entering the atmosphere as the greenhouse gas carbon dioxide.
