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 ...
Once calculated the radial velocity of currents, distance to target, and the angular direction to target it is possible to determine the current vector and to construct current vector maps. In fact, for the area in which vector data from two CODAR sites overlap, it is possible to calculate the velocity and direction of the current and ...
A 2-dimensional or 3-dimensional velocity map, showing the spatial velocity difference of the subsurface, can thus be created for observing the geological structures. Subsurface mapping by ambient noise tomography can be applied in different fields, such as detecting the underground void space, [ 4 ] monitoring landslides , [ 5 ] and mapping ...
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.
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.
December 11, 2024 at 2:01 PM Frigid conditions are expected over a large swath of the contiguous U.S. in the aftermath of a powerful cold front moving through the East Coast on Wednesday ...
