Stable isotope and chemical data for thermal waters and fumarolic exhalations from the Rabaul caldera in Papua New Guinea. The dataset includes D/H and O18/O16 ratios, anion ratios, and trace metal contents like Fe, Mn, and Zn. It was published by the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Modeling fluid mixing processes based on stable isotope ratios indicative of meteoric and marine water sources.
- Investigating the leaching potential of geothermal fluids based on enhanced Fe, Mn, and Zn values in springs.
- Reconciling conflicting hypotheses about fluid origins using combined stable isotope and chemical trace data.
- Analyzing the near-surface chemical evolution of acid, mineralised geothermal waters.
Strengths
- Includes stable isotope data (D/H and O18/O16 ratios) grouped into distinct areas.
- Contains chemical data such as anion ratios and trace metal contents (Fe, Mn, Zn).
- Focuses on a specific, active volcanic region: the Rabaul caldera in Papua New Guinea.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in HTML and PDF formats, which may require extraction for analysis.
