|---|
| 30 | !! Updates for the ROAM project include: |
|---|
| 31 | !! - addition of DIC, alkalinity, detrital carbon and oxygen tracers |
|---|
| 32 | !! - addition of air-sea fluxes of CO2 and oxygen |
|---|
| 33 | !! - periodic (monthly) calculation of full 3D carbonate chemistry |
|---|
| 34 | !! - detrital C:N ratio now free to evolve dynamically |
|---|
| 35 | !! - benthic storage pools |
|---|
| 36 | !! |
|---|
| 37 | !! Opportunity also taken to add functionality: |
|---|
| 38 | !! - switch for Liebig Law (= most-limiting) nutrient uptake |
|---|
| 39 | !! - switch for accelerated seafloor detritus remineralisation |
|---|
| 40 | !! - switch for fast -> slow detritus transfer at seafloor |
|---|
| 41 | !! - switch for ballast vs. Martin vs. Henson fast detritus remin. |
|---|
| 42 | !! - per GMD referee remarks, xfdfrac3 introduced for grazed PDS |

|---|
| 48 | !! Updates with the addition of MOCSY include: |
|---|
| 49 | !! - option to use PML or MOCSY carbonate chemistry (the latter is |
|---|
| 50 | !! preferred) |
|---|
| 51 | !! - central calculation of gas transfer velocity, f_kw660; previously |
|---|
| 52 | !! this was done separately for CO2 and O2 with predictable results |
|---|
| 53 | !! - distribution of f_kw660 to both PML and MOCSY CO2 air-sea flux |
|---|
| 54 | !! calculations and to those for O2 air-sea flux |
|---|
| 55 | !! - extra diagnostics included for MOCSY |

| 145 | !! ** Method : each now biological flux is calculated in function of |

|---|
| 147 | !! depending on the tracer, these fluxes are sources or |
|---|
| 148 | !! sinks. |
|---|
| 149 | !! The total of the sources and sinks for each tracer |
|---|
| 150 | !! is added to the general trend. |
