January 02, 2026 to February 25, 2026 voyage collected hydrology samples from the RV Investigator during the COOKIES expedition. The processed dataset contains measurements of salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, and ammonium from Niskin bottles at various depths. It is archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
Use Cases
- Modeling ocean biogeochemical cycles based on nutrient concentration data (phosphate, silicate, nitrate)
- Analyzing water column stratification based on salinity and temperature profiles from CTD deployments
- Studying dissolved oxygen dynamics in Antarctic waters based on oxygen measurements
- Investigating nutrient sources and sinks in the Cook Ice Shelf region based on ammonium and nitrate data
Strengths
- Data is quality-controlled and processed, as stated in the description
- Specific parameters analyzed are listed: salinity, dissolved oxygen, phosphate, silicate, nitrate plus nitrite, ammonium
- Voyage time range is precisely defined: January 02, 2026 to February 25, 2026
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Description metadata is limited; actual data quality requires manual inspection after download
