High-Frequency Observations of Carbonate Chemistry Inside and Outside a Sugar Kelp Farm

Fiona Teevan-Kamhawi's dataset contains high-temporal-resolution measurements of surface temperature, salinity, dissolved oxygen, and pH taken every 30–60 minutes from December 2022 to May 2023. The data was collected inside and outside a 2-acre Saccharina latissima (sugar kelp) farm in Point Judith, Rhode Island, to evaluate the farm's role in mitigating local ocean acidification. The study concluded that the kelp farming provided negligible local mitigation over the full growing season.

Use Cases

• Modeling local-scale carbonate system dynamics based on high-frequency pH and dissolved oxygen measurements.
• Assessing the temporal impact of macroalgae growth on surface water pCO2 based on paired inside/outside farm observations.
• Evaluating the potential of small-scale seaweed aquaculture for ocean acidification mitigation based on a full-season case study.

Strengths

• High-temporal-resolution measurements taken every 30–60 minutes over a full growing season.
• Includes paired observations from inside and outside the 2-acre kelp farm for controlled comparison.
• Data is associated with a specific, peer-reviewed study evaluating a clear scientific hypothesis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (902.8 KB) and its scope is limited to a single, relatively small (2-acre) farm over one season.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
