Seawater Chemistry Near Kuei-Shan-Tao Hydrothermal Vents, 2009-2017

Kuei-Shan-Tao volcano off Taiwan provides a time-series of in situ seawater carbonate chemistry, dissolved metals, and environmental parameters from 2009 to 2017. The data captures the impact of a 2016 M5.8 earthquake and a C5 typhoon on local biogeochemistry. Sampling occurred at White and Yellow hydrothermal vents and in a grid offshore, using Niskin bottles and scuba diving.

Use Cases

• Analyzing changes in carbonate system parameters after catastrophic events like earthquakes and typhoons.
• Mapping the distribution of dissolved major and minor metals around shallow hydrothermal vents.
• Studying temporal variability in seawater environmental parameters in a volcanically active coastal region.

Strengths

• Covers an eight-year time series from 2009 to 2017.
• Captures a unique natural experiment with coincident 2016 earthquake and typhoon events.
• Includes data from multiple sampling methods (Niskin bottles, scuba diving) and analytical techniques (ICP-OES/MS, VINDTA).

Limitations

• Specific column names and row counts are not provided in any source.
• Conflicting last updated dates (2017-12-31 vs. 2026-03-05) suggest potential metadata issues.
• License and author information is missing from all platform entries.
