Error distribution for horizontal (a,b) and vertical (c,d) directions. a and c represent the error distribution of nitrate concentration, while b and d represent the error distribution of phosphate concentration. In areas with high data density, errors are relatively low. The vertical distribution of errors shows an increasing trend in the thermocline (approximately 300 m).
