Description (last modified by )
This update includes several enhancements to the BIO_FENNEL ecosystem module. Many thanks to Katja Fennel and Arnaud Laurent for providing the updated fennel.h, fennel_def.h, fennel_inp.h, fennel_mod.h, fennel_var.h, and fennel_wrt.h files.
- The ecosystem model can be configurated up to 15 biological tracers:
NO3 Nitrate concentration NH4 Ammonium concentration chlorophyll Chorophyll concentration phytoplankton Phytoplankton biomass zooplankton Zooplankton biomass LdetritusN Large detritus N-concentration SdetritusN Small detritus N-concentration LdetritusC Large detritus C-concentration if CARBON SdetritusC Small detritus C-concentration if CARBON TIC Total inorganic carbon if CARBON alkalinity Alkalinity if CARBON oxygen Oxygen concentration if OXYGEN PO4 Phosphate concentration if PO4 RdetritusN River detritus N-concentration if RIVER_DON RdetritusC River detritus C-concentration if RIVER_DON
- If P04 is activated, an additional component is added representing phosphate concentration. With this option, the phytoplankton growth can be limited by either nitrogen or phosphorous (see Laurent et al., 2012).
- RIVER_DON is activated, an additional biological tracer (or two if CARBON is defined) is added, representing the non-sinking dissolved organic matter from rivers described in Yu et al. (2015).
- If the RW14_OXYGEN_SC and or RW14_CO2_SC options are used, the model will use Wanninkhof (2014) air-sea flux parameterization of the Schmidt transfer coefficients. With the TALK_NONCONSERV option, alkalinity is affected by biological fluxes, as described in Laurent et al. (2017).
- With the PCO2AIR_DATA option, atmospheric pCO2 uses Laurent et al. (2017) annual climatory curve. The PCO2AIR_SECULARoption provides an alternative time-dependent atmospheric pCO2 evolution. If none of the two options are defined, atmospheric pCO2 is constant.
- WARNING: The input bio_Fennel.in script was modified to include new parameters. Also, several new variables were added to the varinfo.dat metadata file.

Also, included minor updates to few files:
- mp_routines.F: Added Fortran 2003 FLUSH (unit) intrinsic to my_flush subroutine to flush the contents of a unit buffer.
- comp_Jb0.F: Removed CPP conditional around USE mod_scalars to avoid compilation errors.
- Change information format in get_2dfld.F, get_2dfldr.F, get_3dfld.F, and get_3dfldr.F.
