Sentences with phrase «deep water formation»

To drive a mean deep water formation, you need a mean surface flux.

The thermohaline circulation of the global ocean is controlled in part by freshwater inputs to northern seas that regulate the strength of North Atlantic Deep Water formation by reducing surface seawater density.

The GSA seems to have originated from a large discharge of ice from the Arctic to the key deep water formation regions of the North Atlantic.

A good way to estimate the effect of the thermohaline part of the heat transport is to shut it down by dumping a lot of freshwater into the north Atlantic in a climate model, which stops deep water formation there.

Enormous amounts of freshwater were released into the North Atlantic following deglaciation, and an influx of freshwater into the North Atlantic Deep Water formation zone can potentially trigger abrupt climate changes.

This will be a surprise to many Arctic researchers who believe deep water formation shuts down during glaciations.»

Most deep water formation (in today's climate) occurs where fairly saline water is chilled to near freezing.

Why are any changes in (imbalances of) deep water formation so critical?

In addition to the main threshold for a complete breakdown of the circulation, other thresholds may exist that involve more - limited changes, such as a cessation or diminishment of Labrador Sea deep water formation (Wood et al., 1999).

In a version of the model without Drake Passage the temperature distribution is symmetric about the equator, due in large part to the fact that the meridional overturning in the ocean is symmetric about the equator with deep water formation in both hemispheres.

For global warming scenarios, additional forcing comes into play: surface warming and enhanced high - latitude precipitation, which will also reduce density of northern surface waters (an effect which alone has shut down deep water formation in some model experiments, e.g. Manabe and Stouffer 1993, 1994).

«The North Atlantic zone of deep water formation,» said Kullenberg, «is a very considerable carbon sink.»

Modelling uncertainty currently is such that in some climate models, this amount of freshwater (without any other forcing) would shut down deep water formation, in some it wouldn't.

[Response: You're talking of cold events that are a response to massive freshwater influx to the Atlantic and a subsequent shut - down of deep water formation.

This suggests that the associated changes in North Atlantic Deep Water formation and in the large - scale deposition of wind - borne iron in the Southern Ocean had limited impact on CO2.

At mid-depth (500 to 2,000 m), the Atlantic and southern end of the Pacific section show widespread change, but the North Pacific signal is weaker and shallower because it has only weak intermediate water formation (and no deep water formation).

Changes in Arctic Sea Ice suggest that there have been changes in deep water formation.

Ferreira, D., P. Cessi, H. K. Coxall, A. de Boer, H. A. Dijkstra, S. S. Drijfhout, T. Eldevik, N. Harnik, J. F. McManus, D. P. Marshall, J. Nilsson, F. Roquet, T. Schneider, R. C. Wills, 2018: Atlantic - Pacific asymmetry in deep water formation.

A shutoff in North Atlantic Deep Water formation and the associated Atlantic THC can occur if sufficient freshwater (and / or heat) enters the North Atlantic to halt density - driven North Atlantic Deep Water formation (41).

Martinson, D. G. in Deep Convection and Deep Water Formation in the Oceans (eds Chu, P. C. & Gascard, J. C.) 37 — 52 (Elsevier Oceanography Series, 1991).

, 1985: North Atlantic Deep Water Formation.
