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

Abstract:

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.

Methods & Sampling

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.

Data is extracted for 8 different stations:

1. Ross Sea: -77.83N -173.1E

2. Western Antarctic Peninsula: -63.87N -65.42E

3. Pine Island Polynya: -74.82N -102.5E

4. Amundsen Sea Polynya: -73.79N -111.9E

8. Under Dotson: -74.47N -112.4E

11. Ross Sea Central Polynya: -73.35N 177.9E

12. Ross Sea under sea ice: -72.59N -162.9E

15. Prydz Bay: -68.49N 72.84E

Data Processing Description

We ran two different scenarios, 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.
