High-Resolution CTD Profiles from the Indonesian Indian Ocean (1991-1994)

140 CTD casts from the Indonesian research vessel BARUNA JAYA I provide 112,303 high-resolution vertical profiles of ocean properties. Data includes temperature, salinity, density, and possibly dissolved oxygen or transmissivity, recorded at depth intervals as fine as 1 meter. This dataset captures conditions in the Arafura Sea, Bali Sea, and other parts of the Indian Ocean over a nearly three-year period.

Use Cases

• Analyzing vertical thermohaline structure based on temperature and salinity profiles.
• Studying oceanographic variability over time from the 1991-1994 time series.
• Validating regional ocean models using in-situ conductivity-temperature-depth measurements.
• Calculating derived oceanographic parameters like density (sigma-t) from the core data columns.

Strengths

• Contains a substantial volume of 112,303 individual data records.
• Provides high-resolution vertical profiles with sampling as fine as 1-meter intervals.
• Covers a specific multi-year time range from July 1991 to February 1994.

Limitations

• Metadata completeness is low: specific column names, license, and author are not provided.
• There is a conflict in the 'last updated' date between sources (1994 vs. 2026), suggesting potential metadata staleness.
• Documentation gaps exist regarding data processing details like averaging or interpolation methods.
