The related California Current Conservation Complex is a grouping of federally-designated marine protected areas that have been on the UNESCO list of tentative World Heritage Sites since 2017, which includes the following areas found throughout the current: the Point Reyes National Seashore, the Golden Gate National Recreation Area, the ...
In 2010, retailers of modern CODAR equipments guarantee an accuracy typically < 7 cm/s of the total current velocity and 1–2 cm of the tidal component, in normal environment condition. [13] However, the accuracy of the system depends on several factors, such as signal-to-noise ratios, geometry and pointing errors.
A study by Pacanowski (1987) [8] shows that including ocean current velocity through relative wind stress in an Atlantic circulation model reduces the surface currents by 30%. [9] This decrease in surface current can impact sea surface temperature and upwelling along the equator.

This is associated with a decrease in the speed of current; eastward directed speeds at the surface are typically less than 0.05 m/s (5 cm/s) in the central Pacific. As the NPC approaches the west coast of North America, it divides into two broad currents: the northward flowing Alaska Current and the southward flowing California Current.
There are three major wind patterns that lead to Ekman suction or pumping. The first are wind patterns that are parallel to the coastline. [1] Due to the Coriolis effect, surface water moves at a 90° angle to the wind current. If the wind moves in a direction causing the water to be pulled away from the coast then Ekman suction will occur. [1]
At the surface the circulation will set a current from the divergence zone to the convergence zone and the spacing between these zones are of the order of 1–300 m (3–1,000 ft). Below convergence zones narrow jets of downward flow form and the magnitude of the current will be comparable to the horizontal flow.
