CSIRO Marine National Facility collected processed hydrology data during the RV Investigator voyage IN2026_V01 from January 02 to February 25, 2026. The dataset contains water quality parameters like salinity, dissolved oxygen, and nutrients from Niskin bottle samples at various depths. Data is archived at the CSIRO National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
- Analyze nutrient concentration gradients based on phosphate, silicate, nitrate plus nitrite, and ammonium measurements.
- Study dissolved oxygen profiles in Antarctic waters based on depth-stratified sampling.
- Model salinity distribution and water column structure based on Conductivity-Temperature-Depth (CTD) deployment data.
- Investigate relationships between chemical parameters and Antarctic marine ecosystems based on the voyage's 'Cook Ice Ecosystems and Sediments' focus.
Strengths
- Data has been processed and quality-controlled.
- Voyage spanned a specific 55-day period from January 02 to February 25, 2026.
- Parameters analyzed include six specific water chemistry measures: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium.
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 specific Antarctic voyage track.
