|---|
| 26 | !! Updates for the ROAM project include: |
|---|
| 27 | !! - addition of DIC, alkalinity, detrital carbon and oxygen tracers |
|---|
| 28 | !! - addition of air-sea fluxes of CO2 and oxygen |
|---|
| 29 | !! - periodic (monthly) calculation of full 3D carbonate chemistry |
|---|
| 30 | !! - detrital C:N ratio now free to evolve dynamically |
|---|
| 31 | !! - benthic storage pools |
|---|
| 32 | !! |
|---|
| 33 | !! Opportunity also taken to add functionality: |
|---|
| 34 | !! - switch for Liebig Law (= most-limiting) nutrient uptake |
|---|
| 35 | !! - switch for accelerated seafloor detritus remineralisation |
|---|
| 36 | !! - switch for fast -> slow detritus transfer at seafloor |
|---|
| 37 | !! - switch for ballast vs. Martin vs. Henson fast detritus remin. |
|---|
| 38 | !! - per GMD referee remarks, xfdfrac3 introduced for grazed PDS |

|---|
| 45 | !! - option to use PML or MOCSY carbonate chemistry (the latter is |
|---|
| 46 | !! preferred) |
|---|
| 47 | !! - central calculation of gas transfer velocity, f_kw660; previously |
|---|
| 48 | !! this was done separately for CO2 and O2 with predictable results |
|---|
| 49 | !! - distribution of f_kw660 to both PML and MOCSY CO2 air-sea flux |
|---|
| 50 | !! calculations and to those for O2 air-sea flux |

|---|
| 2263 | !! This version of MEDUSA offers a choice of three methods for |
|---|
| 2264 | !! handling the remineralisation of fast detritus. All three |
|---|
| 2265 | !! do so in broadly the same way: |
|---|
| 2266 | !! |
|---|
| 2267 | !! 1. Fast detritus is stored as a 2D array [ ffastX ] |
|---|
| 2268 | !! 2. Fast detritus is added level-by-level [ ftempX ] |
|---|
| 2269 | !! 3. Fast detritus is not remineralised in the top box [ freminX ] |
|---|
| 2270 | !! 4. Remaining fast detritus is remineralised in the bottom [ fsedX ] |
|---|
| 2271 | !! box |
|---|
| 2272 | !! |
|---|
| 2273 | !! The three remineralisation methods are: |
|---|
| 2274 | !! |
|---|
| 2275 | !! 1. Ballast model (i.e. that published in Yool et al., 2011) |
|---|
| 2276 | !! (1b. Ballast-sans-ballast model) |
|---|
| 2277 | !! 2. Martin et al. (1987) |
|---|
| 2278 | !! 3. Henson et al. (2011) |
|---|
| 2279 | !! |
|---|
| 2280 | !! The first of these couples C, N and Fe remineralisation to |
|---|
| 2281 | !! the remineralisation of particulate Si and CaCO3, but the |
|---|
| 2282 | !! latter two treat remineralisation of C, N, Fe, Si and CaCO3 |
|---|
| 2283 | !! completely separately. At present a switch within the code |
|---|
| 2284 | !! regulates which submodel is used, but this should be moved |
|---|
| 2285 | !! to the namelist file. |
|---|
| 2286 | !! |
|---|
| 2287 | !! The ballast-sans-ballast submodel is an original development |
|---|
| 2288 | !! feature of MEDUSA in which the ballast submodel's general |
|---|
| 2289 | !! framework and parameterisation is used, but in which there |
|---|
| 2290 | !! is no protection of organic material afforded by ballasting |
|---|
| 2291 | !! minerals. While similar, it is not the same as the Martin |
|---|
| 2292 | !! et al. (1987) submodel. |
|---|
| 2293 | !! |
|---|
| 2294 | !! Since the three submodels behave the same in terms of |
|---|
| 2295 | !! accumulating sinking material and remineralising it all at |
|---|
| 2296 | !! the seafloor, these portions of the code below are common to |
|---|

|---|
| 2602 | !! separation of what's remineralised sinking through the final |

|---|
| 2604 | !! remineralisation of material that reaches the seafloor (i.e. |
|---|
| 2605 | !! the model assumes that *all* material that hits the seafloor |
|---|
| 2606 | !! is remineralised and that none is permanently buried; hey, |
|---|
| 2607 | !! this is a giant GCM model that can't be run for long enough |

|---|
| 2609 | !! |
|---|
| 2610 | !! in a change to this process, in part so that MEDUSA behaves |
|---|
| 2611 | !! a little more like ERSEM et al., fast-sinking detritus (N, Fe |
|---|
| 2612 | !! and C) is converted to slow sinking detritus at the seafloor |
|---|
| 2613 | !! instead of being remineralised; the rationale is that in |
|---|
| 2614 | !! shallower shelf regions (... that are not fully mixed!) this |
|---|
| 2615 | !! allows the detrital material to return slowly to dissolved |
|---|
| 2616 | !! nutrient rather than instantaneously as now; the alternative |
|---|
| 2617 | !! would be to explicitly handle seafloor organic material - a |
|---|
| 2618 | !! headache I don't wish to experience at this point; note that |
|---|
| 2619 | !! fast-sinking Si and Ca detritus is just remineralised as |

| 2625 | !! seafloor can now be added to sediment pools and stored for |
|---|
