Humic Fulvic Index: A Temporal Fluorescence Index for Iron Carrying Capacity

Heerah, Kavi from Borealis Harvested Dataverse created a dataset supporting a new fluorescence index for dissolved organic matter to track iron carrying capacity. The data includes a year of sampling with fresh and salinity 35 samples. It contains iron measurements and absorbance measurements.

Use Cases

• Develop predictive models for iron speciation based on fluorescence index values.
• Analyze temporal trends in iron carrying capacity over a one-year sampling period.
• Compare water chemistry between fresh and saline (salinity 35) sample conditions.
• Calibrate optical absorbance measurements against direct iron concentration assays.

Strengths

• Data covers a full year of sampling, providing temporal context.
• Includes measurements for both fresh and saline (salinity 35) water samples.
• Contains direct iron measurements alongside absorbance data for method validation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
