Description
41 CTD deployments collected aboard the RV Investigator between October 10 and November 14, 2025, in the Coral Sea Marine Park. The data were processed and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. Measurements include conductivity, temperature, depth, dissolved oxygen, fluorescence, and turbidity from primary and auxiliary sensors.
Use Cases
Modeling deep-sea biodiversity patterns based on water column profiles from 41 CTD deployments.
Analyzing oceanographic conditions in the Coral Sea Marine Park based on conductivity, temperature, and depth data.
Studying phytoplankton dynamics based on chlorophyll fluorescence and PAR sensor data mentioned in the description.
Assessing water quality and clarity based on turbidity and transmissometer measurements.
Strengths
Data from 41 CTD deployments provides repeated spatial and temporal sampling.
Sensor calibration details are provided, including a standard deviation of 0.0025203 PSU for conductivity.
Automated quality control was applied to remove spikes and out-of-range values.
Multiple sensor types were deployed, including dissolved oxygen, fluorescence, and turbidity.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
The final conductivity calibration had a standard deviation marginally outside the target of 'better than 0.002 PSU'.
Row count is unknown, which may limit suitability assessment.
