Sentences with phrase «water mass distribution»

The paleoclimate record suggests that these transitions were accompanied by changes in the ocean's water mass distribution, which likely played a key role in the glacial - interglacial shifts themselves, by affecting ocean carbon storage and thus atmospheric CO2 concentrations.

The highest resolution GFDL model, CM2.6, matched the Northwest Atlantic circulation and water mass distribution most accurately,» said Vincent Saba, a NOAA fisheries scientist and lead author of the study.

The study also found that the warming of the upper 300 meters (roughly 1,000 feet) of the Northwest Atlantic increases salinity due to a change in water mass distribution related to a retreat of the colder, fresher Labrador Current and a northerly shift of the warmer, saltier Gulf Stream.

The aim of my PhD is to use the distribution of diatom species preserved in sediment cores across the Scotia Sea to reconstruct the position of major ocean boundaries and water masses through time.

Changes in the mass distribution of water in Earth's oceans in turn leads to variations in its angular momentum.

Regional variations arise because the Earth's gravity field is affected in multiple ways by the melt of ice, due to the direct effect of surface mass changes (the gravity field is determined by the distribution of mass), the consequent deformation of the Solid Earth (removing a load causes the Earth's surface to rebound, which in turn changes the distribution of the Earth's mass), the consequent redistribution of ocean water (the ocean surface is shaped by the gravity filed) and perturbations of the Earth's rotation axis (because of mass redistribution).

Accounting for the considerable disagreement among satellite - era observational datasets on the distribution of snow water equivalent, CanESM2 has too much springtime snow cover over the Canadian land mass, reflecting a broader Northern Hemisphere positive bias.

Paleonutrient proxies currently provide the strongest constraints on the past spatial distribution of deep water masses.

The closure of the circumtropical seaways is assumed to have triggered and / or strengthened the North Atlantic Deep Water production, initiated the Caribbean Current, strengthened the Gulf Stream, and, therefore, changed the global distribution of deep - water masses, heat and salinity (Haug & Tiedemann1Water production, initiated the Caribbean Current, strengthened the Gulf Stream, and, therefore, changed the global distribution of deep - water masses, heat and salinity (Haug & Tiedemann1water masses, heat and salinity (Haug & Tiedemann1998).

The key to this model lies in the distribution of precipitation on Earth, with maxima in the tropics and in high latitudes, so that the Arctic receives an excess of precipitation over evaporation of about one third, which is associated with the permanent presence of the low salinity surface water mass of the Arctic Ocean, separated by a halocline from the saltier Atlantic water below.

b) volumetric effects — change in the volume of water contained in the oceans and the geometry and areal extent of the ocean basins c) gravitational effects — change in the gravitational attraction of the earth (induced by deformation), by the change in distribution of ice and by the change in self - attraction of the water d) rotational effects — change in the moment of inertia caused by a change in the distribution of mass within the earth and on its surface.

Bigger oceans, different land - mass distribution, different atmospheric chemistry, different sea - water chemistry hotter core / mantle and so on.

In the Arctic that can result in a weaker gulf stream in the North Atlantic, while in the southern ocean, would the same mechanism increase the flow of water into the Humboldt current (what doesn't plunge down has to go somewhere)- behaviour of both currents are different due to land mass distribution.

Primeau, F.W., and M. Holzer, 2006: The ocean's memory of the atmosphere: Residence - time and ventilation - rate distributions of water masses.

In terms of toxic tort and mass tort, we have a national network of top scientific, medical and economic experts in oncology, teratology, epidemiology, toxicology, potable water distribution, contaminant fate and transport, geology, and hydrogeology, among others.
