Davidson Current

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. The current is active year-round at 650 feet (200 meters) below sea level, but surfaces during the winter months, generally from mid-November through mid-February.[1] In these months, northerly winds weaken and are replaced to some extent by southwesterly winds.[3][4]

The Davidson Current was discovered by the American geodesist, astronomer, geographer, surveyor and engineer George Davidson,[5] who was associated with the early California Academy of Sciences (CAS) in San Francisco, California.
