IN2025_V06: Gravity Data from the Coral Sea Frontier Voyage

74 raw data files totalling 5785 MB of gravity measurements collected aboard the RV Investigator voyage IN2025_V06. The Coral Sea Frontier voyage departed Brisbane on 10 October 2025 and returned on 14 November 2025, using a MicroG Lacoste Air-Sea II gravity meter. Data are stored by CSIRO, with additional information in a GSM data acquisition and processing report.

Use Cases

• Modeling regional gravity anomalies based on ship-track survey data.
• Calibrating satellite-derived gravity data based on in-situ sea surface measurements.
• Studying geological structures of the Coral Sea seafloor based on gravity variations.
• Integrating gravity data with other marine geophysical datasets for crustal studies.

Strengths

• 74 raw data files provide a substantial volume of measurements for analysis.
• Data collection includes wharf tie calibrations using a Scintrex Autograv CG-5, which suggests quality control procedures.
• The voyage has a defined temporal coverage from 10 October to 14 November 2025.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Data may reflect geographic bias inherent to the single Coral Sea voyage track.
