<div><p>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 <a href="https://www.bco-dmo.org/dataset/782848">https://www.bco-dmo.org/dataset/782848</a>). </p>
<p>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.</p>
<p>Data is extracted for 8 different stations:</p>
<p>1. Ross Sea: -77.83N -173.1E</p>
<p>2. Western Antarctic Peninsula: -63.87N -65.42E</p>
<p>3. Pine Island Polynya: -74.82N -102.5E</p>
<p>4. Amundsen Sea Polynya: -73.79N -111.9E</p>
<p>8. Under Dotson: -74.47N -112.4E</p>
<p>11. Ross Sea Central Polynya: -73.35N 177.9E</p>
<p>12. Ross Sea under sea ice: -72.59N -162.9E</p>
<p>15. Prydz Bay: -68.49N 72.84E</p></div>

NetCDF output for 8 stations using the circum-Antarctic biological model (CIAO) using model output of dFe dyes & physics as input.
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.
