! Specify variables related to the equation of state.
!
! eq_state_mode    -> choice for empirical formula for equation of state 
!                  1: UNESCO equation of state by Fofonoff and Millard (1983)
!                  2: equation of state according Jackett et al. (2005)
!
! eq_state_method  -> method to compute density and buoyancy from salinity,
!                     potential temperature and pressure
!                  1: full equation of state (i.e. with the LOCAL
!                     pressure). This implies that T is NOT treated as
!                     the potential temperature but rather as the in-situ
!                     temperature!
!                  2: equation of state with pressure evaluated at the surface.
!                     This implies that T is treated as the potential 
!                     temperature and thus rho as the potential density.
!                  3: linearized equation of state at T0,S0,p0 
!                     (again, use p0=p_surf to work with potential
!                     temperature and density.)
!                  4: linear equation of state with T0,S0,dtr0,dsr0
!
! For the precise definition of the following quantities, see 
! GOTM documentation:
!
! T0               -> reference temperature (deg C) for linear equation of state
! S0               -> reference salinity (psu) for linear equation of state
! p0               -> reference pressure (bar) for linear equation of state
! dtr0             -> thermal expansion coefficient for linear equation of state
! dsr0             -> saline expansion coefficient for linear equation of state
