CO2 System Measurements in Hillsborough River, Florida

This dataset contains CO2 system data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center to investigate the effects of HgCl2 on low salinity organic rich estuarine water samples in the Tampa Bay estuary located in west central Florida. Discrete water samples were collected from two 30L Niskin bottles that captured surficial waters. Water samples collected from one Niskin bottle were poisoned with HgCl2 while water samples collected from the second Niskin were left unpoisoned. Water samples were analyzed incrementally over a period of three months at the USGS Carbon Analytical Laboratory in St. Petersburg Florida. This data set contains the experimental results over elapsed time of three CO2 system parameters including: water temperature (Celsius, C), salinity, pHT (pH on the total scale), total alkalinity (AT, micromoles/kg) and total dissolved inorganic carbon (CT, micromoles/kg). For further information regarding data collection and/or processing methods, refer to "An Assessment of HgII to Preserve Carbonate System Parameters in Organic-Rich Estuarine Waters" by Moore and others (2023).
