Description
CTD data from 83 deployments during the RV Investigator voyage IN2024_V03, which took place from May 01 to May 31, 2024. The data were collected using a Sea-Bird SBE911 CTD unit and auxiliary sensors, processed with automated quality control, and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre. The voyage aimed to untangle causes of change in the southeast marine ecosystem over 25 years.
Use Cases
Analyzing water column profiles based on conductivity, temperature, and depth (CTD) data.
Studying dissolved oxygen dynamics based on calibrated sensor data.
Investigating relationships between chlorophyll-a, CDOM, and PAR measurements for marine productivity.
Assessing data quality and sensor performance based on the documented calibration and QC procedures.
Strengths
Data from 83 CTD deployments provides multiple sampling points.
Final conductivity calibration achieved a standard deviation of 0.0018351 PSU, within the target of better than 0.002 PSU.
Dissolved oxygen calibration fit had a standard deviation of 0.83297 μM, with good agreement between CTD and bottle data noted.
Includes auxiliary sensor data for altimeter, PAR, CDOM, chlorophyll-a, and scattering.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
CTD had minor issues at the beginning of the voyage, and LADCP had a battery failure for the first three casts.
