gsw_SA_from_SP {gsw} | R Documentation |
Calculate Absolute Salinity from Practical Salinity, pressure, longitude, and latitude.
gsw_SA_from_SP(SP, p, longitude, latitude)
SP |
Practical Salinity (PSS-78) [ unitless ] |
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
.
