either "unesco" or "teos". If the latter, then the
computer must have the TEOS library installed; see teos.
Value
In-situ salinity [PSU].
Details
Finds the salinity that yields the given density, with the
given temperature and pressure. The method is a bisection search with
a salinity tolerance of 0.001. The isopycnal lines on
temperature-salinity diagrams (plotTS) are computed
with this function.
