High-resolution (4-km) circum-Antarctic ocean-ice shelf model: Whole Antarctica Ocean Model (WAOM4)
The Whole-Antarctic Ocean Model (WAOM) is based on the Regional Ocean Modelling System (ROMS) with thermodynamic ice shelf interactions following Galton-Fenzi et al. (2012)¹. WAOM simulations of the present-day (year 2007) were used to investigate the physical drivers of Antarctic ice shelf basal melting via an ocean heat budget in a longitudinal framework. Ice shelves buttress the Antarctic Ice Sheet and therefore are critical in the dynamics of ice sheet instability and its contribution to sea level rise. New insights into the seasonal melting mechanisms and its importance at circum-Antarctic scale were investigated in Dias et al (2025)².

Resource lineage
- Statement
- The Whole-Antarctica Ocean Model is based on the Regional Ocean Modelling System (https://www.myroms.org/) and is an open-source model; the specific ROMS version contains modification for the ice shelf coupling (https://github.com/bkgf/ROMSIceShelf_devel). All the model forcings are also open-source (ERA-Interim, ECCO2, SOSE initiatives). The model runs in a HPC environment at the National Computational Infrastructure (NCI), and all its outputs are stored in the Gadi gdata (gv90 and e14 projects). Model pre- and post-processing scripts are publicly available in my GitHub (https://github.com/fabiobdias/waom_notebook).
