NEMO v4.2 eORCA1: Antarctic Ice Shelf Cavity Simulations

Antarctic ocean model output from the NEMO v4.2 global configuration comparing simulations with closed and explicitly open cavities beneath the Filchner-Ronne, Larsen C, and Ross ice shelves. The dataset includes namelists, domain files, initial conditions, and model output fields like temperature and salinity for the period 1981-2009. It was produced by Katherine Hutchinson at the Centre National de la Recherche Scientifique.

Use Cases

• Comparing simulated ocean properties with World Ocean Atlas observations based on the provided temperature and salinity fields.
• Analyzing circulation patterns beneath specific Antarctic ice shelves based on the explicitly simulated Filchner-Ronne, Larsen C, and Ross cavities.
• Investigating the impact of cavity representation on melt rates based on the comparison between 'Closed' and 'Open' model runs.
• Visualizing thermohaline and velocity fields in the Filchner-Ronne cavity using the provided extracted data and plotting scripts.

Strengths

• Includes both a reference 'Closed' cavity simulation and an 'Open' simulation for direct comparison.
• Initial conditions are informed by idealized regional configurations merged with World Ocean Atlas data.
• Provides extracted data sections corresponding to real-world CTD measurement dates for validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
