northward_sea_water_velocity_vertical_mean_over_pelagic_layer The vertical mean of northward sea water velocity in the pelagic layer of the ocean. The northward sea water velocity is a vector quantity. "Northward" indicates a vector component which is positive when directed northward. The pelagic layer considers 3 vertical pelagic layers, The epipelagic layer is the ocean layer with light levels sufficient for photosynthesis. The upper mesopelagic layer is the upper half of the ocean layer that isn't totally dark but has light levels that are insufficient for photosynthesis. The lower mesopelagic layer is the lower half of the ocean layer that isn't totally dark but has light levels that are insufficient for photosynthesis.
