Arlindo '98: CTD and Bottle Profiles from Indonesian Seas

NCEI Accession 0157460 contains discrete sample and profile data collected during the Arlindo '98 cruise in February-March 1998. The dataset includes measurements of chlorofluorocarbons, dissolved oxygen, nutrients, salinity, and temperature from the Indonesian seas. It is part of the GLODAPv2 collection and was collected by researchers from Lamont-Doherty Earth Observatory and the University of Miami.

Use Cases

• Analyzing chlorofluorocarbon (CFC-11, CFC-12) concentrations to trace ocean ventilation and circulation patterns.
• Studying nutrient (nitrate, nitrite, phosphate, silicate) distributions to assess marine biogeochemistry.
• Calculating water mass properties using concurrent measurements of potential temperature, salinity, and hydrostatic pressure.
• Investigating the Indonesian Throughflow's physical and chemical characteristics using spatially resolved profile data.

Strengths

• Data covers multiple seas (Banda, Ceram, Flores, Makassar Strait, Molucca) providing regional spatial coverage.
• Includes multiple chemical tracers (CFCs, nutrients, oxygen) alongside core physical parameters.
• Data collection is tied to a specific, well-known research cruise (Arlindo '98) and integrated into the GLODAPv2 compilation.

Limitations

• Exact row count, column names, and dataset size are unknown across all sources.
• Sources provide conflicting last updated dates (1998-03-05 vs. 2026-03-05), indicating potential metadata inconsistency.
• One source lists an author affiliation as unknown, suggesting incomplete provenance metadata.
