739	Updated the Red Tide model	arango		"The red tide model ('''RED_TIDE''') was updated to include a '''Q10''' mortality rate equation, as a function of temperature. It includes new input parameters in '''red_tide.in''':
 {{{
! Mortality rate Q10 equation parameters, as a function of temperature:
!
!   M_rate = Mor_a * Mor_Q10^[(temperature-MOR_To)/10] + Mor_b

         MOR_a == 0.04d0                         ! amplitude, 1/day

         MOR_b == 0.03d0                         ! intercept, 1/day

       MOR_Q10 == 10.0d0                         ! reaction rate base

        MOR_T0 == 15.0d0                         ! background temperature (C)
}}}

A couple of input parameters are also adjusted in '''red_tide.in''' for the Gulf of Maine:
 {{{

! Maximum growth rate at optimal temperature and salinity [1/day]

          Gmax == 1.05d0                        ! Gmax

! Germination depth [cm]

            Dg == 0.18d0                         ! Dg
}}}

The '''BIO_TOY''' example gives the following Alexandrium Fundyense concentration:

Notice that I am plotting the LOG of the concentration.

Many thanks to '''Yizhen Li''' for the testing and update of the Red Tide Model."	upgrade	closed	major	Release ROMS/TOMS 3.7	Nonlinear	3.7	Done
