Within the Southern California Bight, a sub-region of the California Current has unique physical properties. Upwelling is fairly weak in the California Bight and Smith and Eppley (1982) stated that the 16-year average for primary production was 0.402 grams carbon/(meter-squared × day), or approximately 150 grams carbon/(meter-squared × year).
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.
The California Current System comprises the eastern boundary of the North Pacific Subtropical Gyre and flows south along the coast of California. Here coastal upwelling drives the eastern boundary current and an undercurrent that flows poleward. In the western region of the North Pacific, the surface of the Subtropical Gyre generally has a "C ...
In oceanography, the Davidson Current is a coastal countercurrent of the Pacific Ocean running north along the western coast of the United States from Baja California, Mexico to northern Oregon, ending at about latitude 48°N, [1] [2] Its flow is adjacent to the California Current, but it flows north rather than south and hugs the coastline.

So, the counter current is called South Equatorial Counter Current (SECC) here. The NEC sits right on the equator, across a longitude from 45°-100°E. The typical speed in the winter can reach up to 50 c m ⋅ s − 1 {\displaystyle 50cm\cdot s^{-1}} , thanks to the northeast seasonal wind from the continent.
