Heard Island Ocean Current Measurements from 1990-1991

Current meter data from a single mooring with five instruments deployed near Heard Island in the Southern Ocean. The dataset covers the period from May 1990 to January 1991 and has been processed and archived by the CMR Data Centre in Hobart. Parameters likely include east-west and north-south velocity components, water temperature, pressure, and salinity.

Use Cases

• Modeling ocean circulation patterns based on velocity component data.
• Analyzing seasonal water property changes based on temperature and salinity time series.
• Studying vertical water column structure based on pressure and depth data.
• Validating regional climate models based on in-situ Southern Ocean measurements.

Strengths

• Data is from a defined time range (May 1990 to January 1991).
• Collected from a specific location (Heard Island, Southern Ocean).
• Comes from a processed and archived source (CMR Data Centre).
• Includes data from five instruments on a single mooring.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single, short-term deployment.
