- Output from the MEDUSA model (Yool et al., GMD, 2013)
- NEMO resolution 1/4-degree
- Regridded from ORCA025 grid to a regular 0.25-degree grid
- Simulation performed as part of the ROAM project (UK Ocean
- Acidification Research Programme; grant number NE/H017372/1)
- CMIP5 Historical and RCP 8.5 extension (1975-2099 inclusive)
- Simulation described in Yool et al., JGR, 2015:
  Yool, A., Popova, E. E., & Coward, A. C. (2015). Future change in ocean
    productivity: Is the Arctic the new Atlantic? Journal of Geophysical
    Research, 120, 7771–7790.

- Subset of output prepared for Mission Atlantic project by A. Yool in 
  April 2021
- Seafloor fields of physical and biogeochemical properties for the 
  periods 2016-2025 and 2090-2099
- Fields of output produced as follows:
  - din   = dissolved inorganic nitrogen, mmol N / m3
  - dip   = dissolved inorganic phosphorus, mmol P / m3 (= din / 16)
  - flux  = seafloor organic carbon flux, mmol C / m2 / d
  - hplus = [H+] ion concentration, umol / m3
  - omarg = omega aragonite, -
  - omcal = omega calcite, -
  - oxy   = dissolved oxygen, mmol O2 / m3
  - pH    = pH, -
  - sal   = salinity, PSU
  - sil   = dissolved silicic acid, mmol Si / m3
  - tmp   = potential temperature, degrees C
- bathy_area = seafloor depth and grid cell area
- Files are netCDF, and include latitude and longitude fields
