RV Investigator Voyage IN2024_V03: Acoustic Doppler Current Profiler Data

Acoustic Doppler Current Profiler (ADCP) data collected during the RV Investigator voyage IN2024_V03, titled 'Untangling the causes of change over 25 years in the southeast marine ecosystem (SEA-MES Voyage 2)'. The voyage took place between May 01, 2024 and May 31, 2024, departing from Hobart and returning to Sydney. Data were processed and archived by CSIRO National Collections and Marine Infrastructure (NCMI) Information and Data Centre (IDC).

Use Cases

• Analyzing ocean current profiles based on ADCP measurements collected during transits and CTD casts.
• Calibrating acoustic instruments based on bottom tracking data collected during the first hour of the voyage.
• Studying changes in marine ecosystems over time based on data from the SEA-MES Voyage 2 mission.
• Investigating continental shelf oceanography based on data collected primarily in that region.

Strengths

• Data were post-processed using the Common Ocean Data Access System (CODAS), a documented standard.
• A processing report is linked, indicating documented quality control.
• Specific instrument configurations are documented, such as the drop keel set at 2 m and nominal transducer depth of 6 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The OS75 and WH75 ADCPs were turned off for the entire voyage, limiting data from those instruments.
