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 ...
The North Pacific Current flows east, eventually bifurcating near the west coast of North America into the northward flowing Alaska Current and the southward flowing California Current. [17] The Alaska Current is the eastern boundary current of the subpolar Alaska Gyre, [ 18 ] while the California Current is the eastern boundary current that ...

Ekman transport is the net motion of fluid as the result of a balance between Coriolis and turbulent drag forces. In the picture above, the wind blowing North in the northern hemisphere creates a surface stress and a resulting Ekman spiral is found below it in the water column.
Ekman spiral – Velocity profile of wind driven current with depth; Ekman transport – Net transport of surface water perpendicular to wind direction; Ekman velocity – Formula for wind induced water current velocity; Tea leaf paradox – Fluid dynamics phenomenon; Stewartson layer – Shear layer connecting differentially rotating regions
A geostrophic current is an oceanic current in which the pressure gradient force is balanced by the Coriolis effect. The direction of geostrophic flow is parallel to the isobars , with the high pressure to the right of the flow in the Northern Hemisphere , and the high pressure to the left in the Southern Hemisphere .
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.
A Wind generated current is a flow in a body of water that is generated by wind friction on its surface. Wind can generate surface currents on water bodies of any size. The depth and strength of the current depend on the wind strength and duration, and on friction and viscosity losses, [1] but are limited to about 400 m depth by the mechanism, and to lesser depths where the water is shallower.
