Notes:

(1) Number 17 and 20 are deviations from the reference value of 1000 kg m–3.

(2) The x- and y- components of water velocity are not necessarily equivalent to the u- and v- components (eastward/northward). The x- and y- components strictly follow the defined coordinate system which may or may not follow the eastward and northward directions.
