Stable isotope and chemical studies of volcanic exhalations and thermal waters from the Rabaul caldera in Papua New Guinea, aggregated by the Australian Ocean Data Network. The data includes D/H and O18/O16 ratios, anion ratios, and trace metal contents (Fe, Mn, Zn) for waters in Matupi Harbour and Sulphur Creek, and fumarolic exhalations from Tavurvur and Rabalankaia volcanoes. The dataset was last updated on 2026-04-10.
Use Cases
- Modeling geothermal fluid mixing processes based on stable isotope (D/H, O18/O16) ratios.
- Investigating water-rock interaction and leaching potential based on trace metal (Fe, Mn, Zn) contents.
- Comparing hypotheses of fluid origin (meteoric vs. marine) based on combined isotope and anion ratio data.
- Characterizing near-surface geochemical evolution of acid, mineralized geothermal waters.
Strengths
- Includes stable isotope data (D/H, O18/O16 ratios) grouped into distinct areas.
- Contains complementary chemical data including anion ratios and trace metals (Fe, Mn, Zn).
- Focuses on a specific, well-defined volcanic system (Rabaul caldera, 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 is provided in PDF/HTML formats, which may require extraction for computational analysis.
