Figure F3. Quantities averaged through the upper 30 m of the model, which correspond roughly to the Ekman layer and the mixed layer depth (with exceptions as noted below). A. Annual average temperature (top) and salinity and current vectors (centimeters per second) (bottom) in this layer. B. AMJ average temperature and streamlines (top) and AMJ salinity and current vectors (centimeters per second) (bottom) in the Ekman Layer (upper 30 m). C. OMD average temperature and streamlines (top) and OMD salinity and current vectors (centimeters per second) (bottom) in the Ekman Layer (upper 30 m). D. Annually averaged upwelling into the upper 30 m (Ekman Layer) (top) and streamlines (bottom) are shown. Green to blue = regions of weak upwelling, white = areas of mean downwelling. Estimated seawater
