Antarctic Bottom Water Formation Model Outputs from ACCESS-OM2-01

Model outputs from the ACCESS-OM2-01 ocean-sea ice model investigating Antarctic Bottom Water formation, variability, and sensitivity to resolution. The data was produced by a project associated with the Australian Ocean Data Network and was last updated in July 2026. It likely contains results from simulations analyzing interannual variability, resolution sensitivity (1/10°, 1/20°, 1/40°), and the effects of wind and meltwater changes on salinity.

Use Cases

• Analyze interannual variability of Antarctic Bottom Water formation based on simulated formation and export data.
• Assess model sensitivity to horizontal resolution based on comparisons of AABW transport at 1/10°, 1/20°, and 1/40° resolutions.
• Investigate mechanisms of salinity change in the Ross Sea based on simulated effects of wind and meltwater input variations.
• Study the relationship between atmospheric forcing and deep water convection based on the described link between easterly winds and sea ice import.

Strengths

• Based on a high-resolution ocean-sea ice model (ACCESS-OM2-01) used for multiple research projects.
• Includes sensitivity analysis across three defined horizontal model resolutions (1/10°, 1/20°, 1/40°).
• Quantifies specific impacts, such as a 27% increase in AABW transport at 1/20° resolution compared to 1/10°.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is model output; accuracy is contingent on model physics and parameterizations.
