Pacific Ocean Iodine-129 Levels from Southern California, 2011–2020

A 2011–2020 time series of Iodine-129 concentrations in coastal Pacific Ocean waters near California, collected to detect potential radionuclide signals from the Fukushima nuclear accident. The dataset includes samples from Scripps Pier and Newport Beach, California, USA, and was published by A. J. Timothy Jull under a CC-BY-4.0 license. No distinct Fukushima signal was identified, but a systematic seasonal pattern was recorded.

Use Cases

• Analyzing seasonal patterns in coastal radionuclide concentrations based on the systematic time series record.
• Modeling Pacific Ocean surface current transport of radionuclides based on the monitoring program's temporal and spatial coverage.
• Assessing the long-term environmental impact of the Fukushima nuclear accident based on the 2011–2020 monitoring record.
• Studying coastal circulation variations using the recorded Iodine-129 levels as a tracer.

Strengths

• Provides a 10-year time series (2011–2020) of environmental monitoring data.
• Includes samples from two distinct coastal locations in California: Scripps Pier and Newport Beach.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is contained in a PDF file (166.4 KB), which may require extraction for computational analysis.
