Northerly North Pacific High (NPH) winds generate a southward surface flow and a consequent offshore Ekman transport inducing upwelling. 4.2 Main features
The Ekman transport relation implies a corresponding pattern of convergences and divergences in the Ekman transport that should be detectable through the Ekman pumping of ocean current gyres (Fig. 2). For example, the theory suggests that the persistent easterly Trade Winds in the tropics will force a poleward Ekman transport; the mid-latitude westerlies will force an equatorward Ekman transport. In Ekman layer …to place, so does the Ekman transport, forming convergence and divergence zones of surface water. A region of convergence forces surface water downward in a process called downwelling, while a region of divergence draws water from below into the surface Ekman layer in a process known as upwelling.

Transport estimated from the observed currents is mostly equatorward and in good agreement with the Ekman transport computed,from four different gridded wind products. Ekman transport piles up surface water in some areas of the ocean and removes water from other areas, producing variations in the height of the sea surface, causing it to slope gradually. One consequence of a sloping ocean surface is the generation of horizontal differences (gradients) in water pressure. Ekman-Jensen Maskin och Transport AB - Org.nummer: 5592064421.
Sökresultaten By combining Ekman theory with rotary signal-processing techniques, we have used high-frequency sea-ice velocity as a proxy for the strength of Ekman transport, and thereby of high-frequency ice-ocean dynamics important for the exchange of heat and momentum between polar oceans and the atmosphere.

Mr. Lima discusses how the surface winds and the coriolis effect combine to create current patterns that circulate nutrients and heat throughout the oceanic Ekman transport moves the surface layer 90 o to the right of the wind, meaning the net Ekman transport is in an offshore direction. The water displaced near the coast is replaced by cold, nutrient-rich deeper water that is brought to the surface through upwelling, leading to high productivity (Figure 9.5.3). History. Ekman developed the theory of the Ekman layer after Fridtjof Nansen observed that ice drifts at an angle of 20°–40° to the right of the prevailing wind direction while on an Arctic expedition aboard the Fram.Nansen asked his colleague, Vilhelm Bjerknes to set one of his students upon study of the problem. Bjerknes tapped Ekman, who presented his results in 1902 as his doctoral thesis.

Oceanographers have long sought to verify the theoretical Ekman transport relation, which predicts that a steady wind stress acting together with the Coriolis fo

This current then gives rise to Ekman transport which is essentially the mass transport per meter that is perpendicular to the Ekman Spiral (see the You Tube
Ekman transport is the direct wind driven transport of seawater; Boundary layer process; Steady balance among the wind stress, vertical eddy viscosity & Coriolis
Ekman transport – the movement of ocean water caused by wind blowing steadily over the surface layers – is one of the most important variables in the study of
Because of the Earth's rotation, the surface ocean transport induced by the wind is directed (outside the equatorial regions) This is called the Ekman transport.

Ekman transport describes horizontal and vertical motion in the mixed layer in response to a steady-state wind forcing. ▷ Sverdrup transport describes the zonal
The Swedish scientist Walfrid Ekman d Ekman Transport Water in the ocean can be divided roughly into three regions based on density: surface water, the pycnocline, and deep water. The pycnocline (also called the thermocline or halocline: recall that seawater density (pycno) is determined by temperature (thermo) and salinity (halo).

Figure 1: Transport timeseries obtained from the first 14.4 years of observations at 26.5°N. The different curves show the MOC (red line) and its constituents, i.e. the transport through the Florida Straits (blue line), the Ekman transport (black line), and the density driven transport obtained from the mooring data (pink line).
Where Ekman transport moves surface waters toward the coast, the water piles up and sinks in the process known as coastal downwelling. Upwelling and downwelling illustrate mass continuity in the ocean; that is, water is a continuous fluid so that a change in distribution of water in one area is accompanied by a compensating change in water distribution in another area.
