NetCDF output for 8 stations using the circum-Antarctic biological model (CIAO). Two different scenarios were run, one where meltwater from ice shelves were a source of iron (20 nM) and one where meltwater from ice shelves were set to 0. A previous calculated model (see related dataset) was used as input.
NetCDF output for 8 stations using the circum-Antarctic biological model (CIAO) using model output of dFe dyes & physics as input. Two different scenarios were run, one where meltwater from ice shelves were a source of iron (20 nM) and one where meltwater from ice shelves were set to 0. A multi-year run was performed. Output is included of the second year model output.

For our model simulations we used the following output of the last year run of the circum-Antarctic ROMS model: horizontal (u and v direction) and vertical velocities, ice concentration and thickness, snow thickness, ice shelf thickness, temperature and salinity fields, heat fluxes, short and longwave radiation (see https://www.bco-dmo.org/dataset/782848).
For model description, see Taglibue & Arrigo publications (2005 and 2006). Additional modifications were made to match Fe inputs with the other data set in the project, see Arrigo et al. (2020) publication.
