Baffin Bay Estuary Carbon Degradation Time Series and Isotope Data

Eight time series from 2017-08-11 to 2017-10-25 investigate photochemical degradation effects on the carbon cycle in Baffin Bay, Texas. The dataset includes measurements of dissolved inorganic carbon, its stable carbon isotopes, dissolved organic carbon isotopes, and chlorophyll a from closed-system incubation experiments. Data originates from a NOAA NCEI project and is hosted on multiple government platforms.

Use Cases

• Calculating photochemical production rates of dissolved inorganic carbon from concentration changes.
• Analyzing the stable carbon isotope composition (δ13C) of photochemically degraded dissolved organic carbon.
• Modeling carbon cycle dynamics in a eutrophic estuary using time-series DIC and DOC isotope data.
• Correlating initial chlorophyll a measurements with subsequent carbon transformation rates in incubations.

Strengths

• Contains eight complete experimental time series, providing repeated measures for analysis.
• Includes stable carbon isotope data for both dissolved inorganic and organic carbon, enabling source tracking.
• Covers a defined temporal range from August to October 2017 for seasonal process study.
• Hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating vetting and importance.

Limitations

• Critical metadata conflicts exist: last update dates are reported as both 2017-10 25 and 2026-03-01.
• Specific column names, row counts, and file sizes are unknown across all provided sources.
• Chlorophyll a was only measured at incubation start, limiting its use as a co-varying time series.
