Nitrogen Flux and Travel Time Data from a Restored Massachusetts Wetland, 2016-2024

Tidmarsh, a former cranberry farm restored to a wetland in Plymouth, Massachusetts, is the source of this data. The dataset contains surface water discharge, nitrogen and nitrate concentrations, and specific conductivity measurements collected between 2016 and 2024. It was created by the Department of Agriculture to support watershed-scale modeling and analysis of nutrient retention.

Use Cases

• Watershed-scale water quality modeling to determine nitrogen sources based on discharge and concentration data.
• Quantifying seasonal patterns of nitrate retention based on weekly field measurements.
• Analyzing solute residence time and its effect on nitrate retention based on bi-monthly conservative tracer injections.

Strengths

• Data collection spans 8 years (2016-2024), allowing for long-term trend analysis.
• Includes multiple measurement types: discharge, nitrogen concentrations, and specific conductivity.
• Dataset is licensed as CC0-1.0, permitting unrestricted use.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to a single restored wetland site.
