Sentences with phrase «thermohaline oceanic circulation»

Thermohaline oceanic circulation was initiated at this time much like that of the present day.

Not exact matches

This deep water convection is the engine (pump) of the oceanic thermohaline conveyor circulation.

In the case of oceans the energy does penetrate the surface layers and is often carried away for eventual release elsewhere and at another time, depending on the ocean currents and other internal oceanic mechanisms such as the flow of the Thermohaline Circulation with a period of more than 800 years for a full circuit.

«It is often known, from modelling studies, that a certain mode of climate tipping (of the oceanic thermohaline circulation, for example) is governed by an underlying fold bifurcation.

Deep oceanic currents are driven by thermohaline circulation and by the rotation of the planet.

The Antarctic ice sheet reached the coastline for the first time at ca. 33.6 Ma and became a driver of Antarctic circulation, which in turn affected global climate, causing increased latitudinal thermal gradients and a «spinning up» of the oceans that resulted in: (1) increased thermohaline circulation and erosional pulses of Northern Component Water and Antarctic Bottom Water; (2) increased deep - basin ventilation, which caused a decrease in oceanic residence time, a decrease in deep - ocean acidity, and a deepening of the calcite compensation depth (CCD); and (3) increased diatom diversity due to intensified upwelling.

No less astonishing is the prevalence of notion that the sluggish density - driven currents known as the «thermohaline circulation» are the main mechanism for oceanic heat redistribution.

In my articles to date I have been unwilling to claim anything as grand as the creation of a new model of climate because until now I was unable to propose any solar mechanism that could result directly in global albedo changes without some other forcing agent or that could account for a direct solar cause of discontinuities in the temperature profile along the horizontal line of the oceanic thermohaline circulation.

The global oceanic conveyer belt, is a unifying concept that connects the ocean's surface and thermohaline (deep mass) circulation regimes, transporting heat and salt on a planetary scale.

1) Abstract «Such changes could have significant ramifications for global sea level, the ocean thermohaline circulation, native coastal communities, and commercial activities, as well as effects on the global surface energy and moisture budgets, atmospheric and oceanic circulations, and geosphere - biosphere feedbacks.

In this paper, it is shown that coherent large - scale low - frequency variabilities in the North Atlantic Ocean — that is, the variations of thermohaline circulation, deep western boundary current, northern recirculation gyre, and Gulf Stream path — are associated with high - latitude oceanic Great Salinity Anomaly events.

Thus as sea ice expands in a cooler climate, the high - latitude oceanic heat loss to the atmosphere is inhibited, the thermohaline circulation weakens, and the sinking regions move equatorward, leading to a shallower and weaker deep circulation.
