ETAS Ocean Model Version 2 - Daily Snapshots

1993-2016 daily snapshots of a high-resolution (~2 km) ocean model for eastern Tasmania. The dataset provides three-dimensional estimates of temperature, salinity, and circulation, organized into yearly files. It is provided by the Australian Ocean Data Network.

Use Cases

• Analyzing long-term temperature and salinity trends based on the 1993-2016 daily estimates.
• Modeling coastal ocean circulation patterns based on meridional, zonal, and vertical current data.
• Studying air-sea interactions based on the included net surface heat flux variable.
• Mapping sea level and density variations for the eastern Tasmanian region.

Strengths

• High spatial resolution of approximately 2 kilometers in the horizontal plane.
• Covers a substantial 24-year time period from 1993 to 2016.
• Provides multiple three-dimensional ocean variables including currents, density, and heat flux.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Data freshness should be verified; the last metadata update is listed as 2026-07-13.
