eReefs GBR4 Hydrodynamic SHOC Model v1.85

eReefs GBR 4 km resolution complete hydrodynamic Sparse Hydrodynamic Ocean Code (SHOC) model data v1.85 contains all tracers present in the SHOC model for the Great Barrier Reef. The output is a non-CF compliant 'standard' SHOC ALL file based on the Arakawa-C grid, with velocities on face centres and tracer values cell centred. This sample dataset was decommissioned in May 2022 and is no longer available via the original NCI THREDDS server.

Use Cases

• Simulating ocean currents and water transport based on the Arakawa-C grid velocity fields.
• Analyzing biogeochemical tracer distributions (e.g., salinity, temperature, nutrients) across the reef system.
• Validating and calibrating other regional ocean models against the SHOC model outputs.
• Studying long-term hydrodynamic trends in the Great Barrier Reef using the complete time-series model data.

Strengths

• Provides a complete set of hydrodynamic tracers from a well-defined model (SHOC v1.85).
• Offers structured geospatial data on a standardized Arakawa-C grid at 4 km resolution.
• Represents a major, cross-platform referenced model output for the Great Barrier Reef.

Limitations

• Dataset is decommissioned and unavailable via its original public server.
• Output format is explicitly non-CF compliant, which may hinder interoperability with standard tools.
• Critical metadata (row count, size, license, author) is consistently missing across all source entries.
