Dear ferreters,
I want to calculate the density with pressure instead of depth (more accuate way), but when I get the pressure with the following scipt to convert the depth to pressure,
let x0 = sin(y[g=v]*3.1415926/180);
let c1 = 5.92E-3 + x0*x0 * 5.25E-3;
let pres = ((1-c1)-(((1-c1)*(1-c1))-(8.84E-6 * z[g=v]))^0.5) / 4.42E-6;
then let rho=rho_un(salt,temp,pres)-1000;
But the results are obviously wrong. Do you have any suggestions?
