IN2023_V07: Antarctic Circumpolar Current Acoustic Doppler Profiles, Nov-Dec 2023

Acoustic Doppler Current Profiler (ADCP) data from the RV Investigator voyage IN2023_V07, focusing on smaller scales of the Antarctic Circumpolar Current south of Tasmania. The voyage took place between November 15 and December 20, 2023, departing from and returning to Hobart. Data were collected using the University of Hawaii Data Acquisition System (UHDAS) and post-processed by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.

Use Cases

• Analyzing ocean current velocity and direction based on ADCP profiles collected from a moving vessel.
• Studying mesoscale variability in the Antarctic Circumpolar Current based on data collected in a meander region.
• Calibrating or validating ocean circulation models based on quality-controlled, ship-collected current data.
• Investigating the performance and data characteristics of different ADCP modes (narrowband vs. broadband) as described in the voyage report.

Strengths

• Data is quality-controlled and archived by CSIRO's National Collections and Marine Infrastructure Information and Data Centre.
• Specific voyage dates (November 15 to December 20, 2023) and departure/return port (Hobart) are documented.
• Detailed instrumentation notes are provided, including the use of WH75kHz and OS150kHz ADCPs in specific modes and transducer depth information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific voyage track.
