_A_r_g_u_m_e_n_t_s:

       S: Salinity, default is 35

       T: Temperature in degrees Celsius, default is 25oC

       P: Hydrostatic pressure in bar (surface = 0), default is 0

    k1k2: "r" for using K1 and K2 from Roy et al. and "m" for using K1
          and K2 from Mehrbach, default is "r"

  phflag: The pH scale is either the total scale (0) or the free scale
          (1), default is 0

     The Roy et al. (1993) constant is recommended by DOE (1994). The
     Merbach et al. (1973) constants used are on the total scale from
     Lueker et al. (2000).
