| 23 | !!---------------------------------------------------------------------- |
|---|
| 24 | !! Updates for the ROAM project include: |
|---|
| 25 | !! - addition of DIC, alkalinity, detrital carbon and oxygen tracers |
|---|
| 26 | !! - addition of air-sea fluxes of CO2 and oxygen |
|---|
| 27 | !! - periodic (monthly) calculation of full 3D carbonate chemistry |
|---|
| 28 | !! - detrital C:N ratio now free to evolve dynamically |
|---|
| 29 | !! - benthic storage pools |
|---|
| 30 | !! |
|---|
| 31 | !! Opportunity also taken to add functionality: |
|---|
| 32 | !! - switch for Liebig Law (= most-limiting) nutrient uptake |
|---|
| 33 | !! - switch for accelerated seafloor detritus remineralisation |
|---|
| 34 | !! - switch for fast -> slow detritus transfer at seafloor |
|---|
| 35 | !! - switch for ballast vs. Martin vs. Henson fast detritus remin. |
|---|
| 36 | !! - per GMD referee remarks, xfdfrac3 introduced for grazed PDS |

| 42 | !! Updates with the addition of MOCSY include: |
|---|
| 43 | !! - option to use PML or MOCSY carbonate chemistry (the latter is |
|---|
| 44 | !! preferred) |
|---|
| 45 | !! - central calculation of gas transfer velocity, f_kw660; previously |
|---|
| 46 | !! this was done separately for CO2 and O2 with predictable results |
|---|
| 47 | !! - distribution of f_kw660 to both PML and MOCSY CO2 air-sea flux |
|---|
| 48 | !! calculations and to those for O2 air-sea flux |
|---|
| 49 | !! - extra diagnostics included for MOCSY |

| 2154 | !! This version of MEDUSA offers a choice of three methods for |
|---|
| 2155 | !! handling the remineralisation of fast detritus. All three |
|---|
| 2156 | !! do so in broadly the same way: |
|---|
| 2157 | !! |
|---|
| 2158 | !! 1. Fast detritus is stored as a 2D array [ ffastX ] |
|---|
| 2159 | !! 2. Fast detritus is added level-by-level [ ftempX ] |
|---|
| 2160 | !! 3. Fast detritus is not remineralised in the top box [ freminX ] |
|---|
| 2161 | !! 4. Remaining fast detritus is remineralised in the bottom [ fsedX ] |
|---|
| 2162 | !! box |
|---|
| 2163 | !! |
|---|
| 2164 | !! The three remineralisation methods are: |
|---|
| 2165 | !! |
|---|
| 2166 | !! 1. Ballast model (i.e. that published in Yool et al., 2011) |
|---|
| 2167 | !! (1b. Ballast-sans-ballast model) |
|---|
| 2168 | !! 2. Martin et al. (1987) |
|---|
| 2169 | !! 3. Henson et al. (2011) |
|---|
| 2170 | !! |
|---|
| 2171 | !! The first of these couples C, N and Fe remineralisation to |
|---|
| 2172 | !! the remineralisation of particulate Si and CaCO3, but the |
|---|
| 2173 | !! latter two treat remineralisation of C, N, Fe, Si and CaCO3 |
|---|
| 2174 | !! completely separately. At present a switch within the code |
|---|
| 2175 | !! regulates which submodel is used, but this should be moved |
|---|
| 2176 | !! to the namelist file. |
|---|
| 2177 | !! |
|---|
| 2178 | !! The ballast-sans-ballast submodel is an original development |
|---|
| 2179 | !! feature of MEDUSA in which the ballast submodel's general |
|---|
| 2180 | !! framework and parameterisation is used, but in which there |
|---|
| 2181 | !! is no protection of organic material afforded by ballasting |
|---|
| 2182 | !! minerals. While similar, it is not the same as the Martin |
|---|
| 2183 | !! et al. (1987) submodel. |
|---|
| 2184 | !! |
|---|
| 2185 | !! Since the three submodels behave the same in terms of |
|---|
| 2186 | !! accumulating sinking material and remineralising it all at |
|---|
| 2187 | !! the seafloor, these portions of the code below are common to |
|---|
