    111111== Units in MEDUSA == 
    112112 
     113Particle fluxes (organic matter and calcite) need to be expressed in MEDUSA as [kg/m2/yr]. The conversion is performed in mod_iloveclim_o2s.F assuming that the units of the particle fluxes coming from OCYCC are [molC/m2/yr]. In flux_to_sediments_mod.f90, particle fluxes are passed to MEDUSA in the variables TPP_mafond and caco3_mafond, which are obtained averaging TPP_ma and caco3_ma, expressed in [molC/m2/day] and multiplying by 360 days to get the values per year. 
     114 
     115TPP_ma is calculated in line 105 of maphot.f taking TPP_m in Tmol and dividing this value by SQRO2 (area in m2) and then dividing the result by a factor of 1.0d-12 which precisely would convert TmolC/m2/year into molC/m2/year, as requested by MEDUSA code. 
     116 
     117Same procedure is repeated in line 262 in maphot.f with caco3_ma.
