gsw_SP_from_SA {gsw} | R Documentation |
Calculate Practical Salinity from Absolute Salinity, pressure, longitude, and latitude.
gsw_SP_from_SA(SA, p, longitude, latitude)
SA |
Absolute Salinity [ g/kg ] |
p |
sea pressure [ dbar ] |
longitude |
longitude in decimal degrees [ 0 to 360 or -180 to 180] |
latitude |
latitude in decimal degrees [ -90 to 90 ] |
If SP is a matrix and if its dimensions correspond to the
lengths of longitude and latitude, then the latter are
converted to analogous matrices with expand.grid
.
Note: unlike the corresponding Matlab function, this does not return a flag indicating whether the location is in the ocean.

gsw_SA_from_SP
does the reverse, while gsw_SP_from_SK
, gsw_SP_from_SR
and gsw_SP_from_Sstar
are similar to this.
