CSIRO Marine and Atmospheric Research processed hydrology data from a 1984 voyage on the North West Shelf. Water samples from Niskin bottles at various depths provide measurements for temperature, salinity, dissolved oxygen, and nutrients. The dataset is archived by the Australian Ocean Data Network.
Use Cases
- Model historical ocean temperature and salinity profiles based on depth measurements.
- Analyze nutrient cycles (phosphate, nitrate, silicate, nitrite) in shelf waters.
- Study dissolved oxygen levels for marine ecosystem health assessments.
- Calibrate modern sensor data against historical bottle sample records.
Strengths
- Data is processed and archived by a recognized research institution (CSIRO).
- Parameters include a core set of seven oceanographic measurements.
- Voyage provides a specific temporal snapshot (25 January - 25 February 1984).
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 bias inherent to the single North West Shelf voyage.
