Description

NetCDF model output of the entire state of the surface layer of the circum-Antarctic model, including ocean and sea ice physical variables, heat and freshwater (negative salt) fluxes between the ice shelves and the ocean, and simulated dFe dyes. Each of the 255 NetCDF (.nc) files contain two five day temporal averages of the model state for the seven years of the model simulation. The additional file "so_grd.rtopo2.2.5km.nc.try16" contains the model grid data (See "Data Files" section).

Methods & Sampling

Model results are from a 5 km horizontal resolution circum-Antarctic Regional Ocean Modeling System circulation model including dynamic sea-ice and static ice shelves (including mechanical and thermodynamic interactions between the floating ice shelves and the water underneath). The results here are just from the surface layer (of 32) of the model, but include all the model state variables (ocean and sea ice), especially the 14 dyes used to represent the different sources of dissolved Fe to the surface waters over the Antarctic continental shelf. Model results are from a seven year period (after a six year spin-up) using repeated 2010 atmospheric forcing. The different dyes are allowed to build up over the continental shelf for the first five years of the simulation and then simulated biological uptake (upper part of water column) and iron scavenging (entire water column) are used during the austral summers to reduce dye concentrations.

More detail on the circum-Antarctic model is in Dinniman et al. (2015) and Dinniman et al. (2020).

Compressed and bundled tar.gz file containing 225 netCDF (.nc) files contain two five day temporal averages of the model state for the seven years of the model simulation.

NetCDF model output of the entire state of the surface layer, including simulated dFe dyes, of the circum-Antarctic.

The number in the netCDF filenames represents the number of model days / 10 from the beginning of the six year model spinup.  Thus, the first file ends at model day 2200 (10 days plus 2190 day spinup) and is numbered 0220.
