It is noteworthy that the results demonstrating the importance of southerly induced Ekman transport for the recruitment of fish larvae to PLE may be underestimated by model constraints.
Northerly winds favored larval dispersion along the continental shelf, and under this condition, Ekman transport was towards offshore and prevented organisms to enter the estuary.
After that time period, surface water starts moving in a direction 90 degrees to the right (in the northern hemisphere), in a phenomena known as the Ekman transport
. If you're focusing your efforts on well-developed weedlines, then that wind would make a difference, because the weeds would become scattered weeds and it's hard to troll through scattered weeds.
The spatial variations of wind stress cause divergence and convergence of Ekman transport, leading to a vertical motion, Ekman pumping (downward) or suction (upward) velocity [w.sub.EK] = 1/[rho][DELTA] x ([tau]/f), at the base of the Ekman layer.
Individual low transport events are caused by both a decrease in the northward Ekman transport as well as an increase in the southward interior transport; thus the overturning weakened as the gyre strengthens (McCarthy et al.
Wind driven ocean currents and Ekman transport

Everywhere wind blows across the surface of the ocean, currents are created, but here the interaction has a powerful additional result: As the barrier wind blows over the ocean's surface, a basic principle of physical oceanography called Ekman transport
takes charge of the actual flow.
Flux and direction of the Ekman transport

melanops) rockfish off northern California over 21 years and evaluated the relationship of abundance to oceanographic variables (sea level anomaly, nearshore temperature, and offshore Ekman transport
The environmental data are in the form of monthly averages of five local variables (air temperature, sea surface temperature, mean sea level, turbulence index and Ekman transport
) recorded at weather and oceanographic stations located on the coast of Antofagasta (23[degrees]26'S).
The offshore Ekman transport
[ILLUSTRATION OMITTED] that results gives rise to intense upwelling along the coast, where cold, nutrient-rich water is brought up to the surface, and to convergence and downwelling in the central and eastern part of the Arabian Sea.
Monthly averages (1950-2002) of the following variables, recorded at coastal stations in the study area, were also analyzed: SST, average sea level (ASL), air temperature (AT), and wind direction and magnitude for estimating Ekman transport
(ET; Bakun et al., 1974) and the turbulence index (TI; Elsberry & Garwood, 1978).
