Description
Discrete sample and profile data collected from the BARUNA JAYA I research vessel across ten Indonesian seas, including the Bali Sea, Java Sea, and Makassar Strait, from January 28 to February 25, 1994. The dataset includes measurements of chlorofluorocarbons (CFC-11 and CFC-12), dissolved oxygen, salinity, water temperature, and hydrostatic pressure, collected using CTD and bottle instruments. It is part of the GLODAPv2 data collection, focusing on the Indonesian Throughflow region.
Use Cases
Tracing ocean ventilation and water mass age using CFC-11 and CFC-12 concentrations.
Analyzing physical oceanographic properties (temperature, salinity, pressure) for circulation models.
Studying dissolved oxygen levels to assess biological activity and water column health.
Investigating the characteristics of the Indonesian Throughflow using cross-basin profile data.
Strengths
Contains specific, traceable measurements for key oceanographic variables, including CFCs.
Data collected over a defined, nearly one-month cruise (1994-01 28 to 1994-02-25) across a significant geographic region.
Associated with a recognized scientific program (GLODAPv2) and cruise (Arlindo '94).
Limitations
Column names and precise row counts are not provided in any source, limiting structural understanding.
Metadata conflicts: the authoritative source (data.gov) lists a future 'last updated' date (2026-03-05), which is inconsistent.
Dataset is from a single cruise in 1994, representing a snapshot in time rather than a long-term record.
