"Eastward" indicates a vector component which is positive when directed eastward (negative westward). "Northward" indicates a vector component which is positive when directed northward (negative southward). Sea water velocity is defined as a two-dimensional vector, with no vertical component. "component_derivative_of_X" means derivative of X with respect to distance in the component direction, which may be northward, southward, eastward, westward, x or y. The last two indicate derivatives along the axes of the grid, in the case where they are not true longitude and latitude. eastward_derivative_of_northward_sea_water_velocity means (d/dy) of the seawater velocity component u, as derived by ocean data models, keeping all other coordinates (x,z,t) constant.
