! Basic settings for biogeochemical model
!
!  bio_calc        -> calculation of the bio model 'bio_model' (.true./.false.)
!  bio_model       -> choice of the bio model:
!                  1: NPZD                     (4 variables)
!                  2: IOW-ERGOM                (9 variables)
!                  3: Suspended matter only    (1 variable)
!                  4: Fasham et al. 1990       (7 variables)
!                  5: IOW-ERGOM MaBenE version (9 variables)
!                  6: ISMER model              (9 variables)
!
!  bio_eulerian    -> state variables are Eulerian (.true./.false.)
!
!  cnpar           -> Cranck-Nicolson parameter for vertical diffusion
!
!  w_adv_discr     -> advection scheme for vertical motion
!                  1: first order upstream
!                  2: not coded yet
!                  3: third-order polynomial
!                  4: TVD with Superbee limiter
!                  5: TVD with MUSCL limiter
!                  6: TVD with ULTIMATE QUICKEST
!
!  ode_method      -> ODE scheme for source and sink dynamics
!                  1: first-order explicit (not positive)
!                  2: second order explicit Runge-Kutta (not positive)
!                  3: fourth-order explicit Runge-Kutta (not positive)
!                  4: Patankar (first order, not conservative)
!                  5: Patankar-RK (second order, not conservative)
!                  6: Patankar-RK (does not work, not conservative)
!                  7: Modified Patankar (1. order, conservat., posit.)
!                  8: Modified Patankar-RK (2. order, conservat., posit.)
!                  9: Modified Patankar-RK (does not work, conservat., posit.)
!                 10: Ext. Modified Patankar (1. order, conservat., posit.)
!                 11: Ext. Modified Patankar-RK (2. order, conservat., posit.)
!
!  split_factor   -> number of biogeochemical time steps per physical time step
!
!  bioshade_feedback -> feedback of bio-turbidity to temp. eq. (.true./.false.)
!
!  bio_lagrange_mean -> averaging Lagrangian conc. on output (.true./.false.)
!
!  bio_npar       -> total number of Lagrangian particles
