Sentences with phrase «for deep ocean»

This is a quite rapid process (for the upper oceans), but much slower for deep ocean temperature changes, which results in the above differences in ratios for short term and long term temperature variations...

If someone comes up with a different and cooler estimate for that deep ocean heat content, I wonder what the next «heat hiding place» will be?

The temperature record is less complete for the deep ocean, and its massive volume and separation from the surface subdues its response to climatic changes.

All in all, I don't see a very convincing case for deep ocean sequestration of heat.

At page 3.44 we read «It will take centuries to millennia for deep ocean temperatures to warm in response to today's surface conditions.»

``... Trenberth is correct that it is possible for the deep ocean to warm while surface warming is seemingly by - passed in the process....»

Since it takes several hundred years for the deep ocean water to cycle up to the top, where it can be warmed up and lose CO2, it makes sense to suppose that if a warming event is initiated by something else (like changes in the amount and spatial distribution of incoming solar radiation,) the concomitant rise in atmospheric CO2 (which would enhance the initial warming) might lag behind by several hundred years.

«Whilst the last decade has seen a rapid increase in good observations of the surface and upper ocean, thanks to Argo floats, we have very few for the deep ocean.»

The lag is a different (and mostly unresolved) problem: while the lag during warming periods is explainable as the about 800 year turnover time for deep ocean down / upwelling flows, the much longer delay of CO2 during periods of cooling towards a new ice age is difficult to explain, the more that methane does follow temperature far more closely, thus errors in ice age — gas age difference are not at the base of the lag...

@ - Pablo an ex Pat «As for the Deep Ocean story it's a meme that smacks of desperation: 1) We can't find the «missing» heat in the atmosphere 2) It has to be here as if it isn't our entire CO2 theory falls apart, it has to be somewhere.

Next — what evidence is there for deep ocean warming and if it is occurring how does that communicate with the weather to make it extreme?

On an earlier thread I made a back - of - envelope calculation that, for the deep ocean to «suck» all the heat down from the surface, so that the sea surface layer and troposphere were nowhere more than 3C, the mean temperature of the deep ocean would need to increase only 0.4 C. Maybe someone could check this.

@ - Goldie «Next — what evidence is there for deep ocean warming and if it is occurring how does that communicate with the weather to make it extreme?»

The authors used proxies that are representative for DEEP ocean temperatures.

This means it will take centuries to millennia for deep ocean temperatures to warm in response to today's surface conditions, and at least as long for ocean warming to reverse after atmospheric greenhouse gas concentrations decrease (virtually certain).

These data show that mixing time scales for the upper thermocline are decadal and mixing time scales for the deep ocean are multi-centennial.

Over the altimetry period (1993 — 2010), the rate for the 0 to 700 m depth range is 0.8 [0.5 to 1.1] mm yr — 1 and 1.1 [0.8 to 1.4] mm yr — 1 when accounting for the deep ocean (Section 3.7.2, Table 3.1, Table 13.1).»

That ratio is not 1:50 for CO2, because CO2 in the deep oceans plays no (immediate) role at the surface (except for deep ocean — atmosphere exchanges, but that is a different topic).

Nor does residence time have anything to do with oceanographers» imaginary bottleneck in the boundary layer, where CO2 waits thousands of years for deep ocean sequestration to make room in the surface layer, constrained by equilibrium carbonate equations.

Yes but for the deep ocean to heat up you first need to get rid of antarctic ice, which causes the cold bottom flow.

Yes, it takes a while for the deep ocean to heat up, but we're not measuring deep ocean heat, we're measuring the air temperature in the boundary layer.

But figures are really just guesstimates for the deep ocean.

Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitivity.

It takes decades for permafrost to warm up and centuries for the deep ocean.

Balance time for those surface layers is short, but for the deep ocean, CO2 doesn't diffuse but is gradually carried there by slow moving ocean currents, these may take on the order of a thousand years to complete.

[OOOPS; this nonlinear effect puts their «alternative concept» into the realm of Trump administration «alternative facts» — BD] Although the deep ocean could dissolve 70 to 80 % of the expected anthropogenic carbon dioxide emissions and the sediments could neutralize another 15 % it takes some 400 years for the deep ocean to exchange with the surface and thousands more for changes in sedimentary calcium carbonate to equilibrate with the atmosphere.

«This is very exciting in terms of its implications for the deep ocean and how mid-ocean ridges work,» he told New Scientist.

I am also interested in how long is required for the surface temp to «achieve» 95 % of the ECS change: e.g. if climate sensitivity is 2K, how much time is required for the surface temp to increase by 1.9 K; and then how much longer for the deep oceans to increase by 1.9 K (or whatever 95 % of the projected increase in deep ocean temperature works out to.)

So it might take several hundred years for the deep oceans (where many of the volcanic vents and mid-ocean ridges are) to warm even a single degree.

But that doesn't hold for the deep oceans, where any effect of increasing CO2 in the atmosphere will show up some 800 years later...

Not so for the deep oceans: what sinks in the NE Atlantic, comes back hundreds of years later (probably mixed with other waters) in the Pacific equator.

But that is by far not the case for the deep oceans and the biosphere.

I am also interested in how long is required for the surface temp to «achieve» 95 % of the ECS change: e.g. if climate sensitivity is 2K, how much time is required for the surface temp to increase by 1.9 K; and then how much longer for the deep oceans to increase by 1.9 K (or whatever 95 % of the projected increase in deep ocean temperature works out to.)
