Geological Survey - St. Petersburg Coastal and Marine Science Center Online_Linkage: https://doi.org/10.5066/P9HS7ZV0 Description: Abstract: This dataset contains carbonate system data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center to investigate the effects of carbon cycling, coastal and ocean acidification on the Tampa Bay estuary located in west central Florida and eastern Gulf of Mexico. Discrete seawater samples were collected periodically (every few weeks to months) at repeat monitoring locations. Water samples were analyzed by the USGS Carbon Analytical Laboratory in St. Petersburg Florida. This dataset contains time series measurements of carbonate system parameters including: water temperature (Celsius, C), salinity, dissolved oxygen (milligrams/L), total alkalinity (TA, micromoles/kg), dissolved inorganic carbon (DIC, micromoles/kg), pHT (pH on the total scale), nitrate + nitrite (NO3+NO2, micromoles/L), nitrite (NO2, micromoles/L), silicate (SIL, micromoles/L), ammonium (NH4, micromoles/L) and phosphate (PO4, micromoles/L). Purpose: This dataset was acquired to assist USGS staff with the quantification, analysis and interpretation of geochemical ​time series data that will ultimately be used in assessments ​and ​research ​of, or related to​ carbon cycling, coastal and ocean acidification. Data were collected during USGS field activity numbers (FAN) 2018-374-FA, 2019-304-FA and 2019-308-FA.

Measured TA values included in this dataset may not be suitable to use for calculating carbonate system parameters, due to the potential influence of organic alkalinity on these values.

CRM analyses are performed daily before and after analysis of samples. Sample values are corrected to CRMs using a correction factor based on the difference between the known and measured values of the CRMs. Precision is determined by repeat analysis of samples and CRMs. Spectrophotometric pH measurements require no calibration. Precision of pH analysis is determined by repeat measurements of replicate samples. Nutrient analyses were performed by the University of Tampa (Dr. Robert Masserini). YSI meters used to collect ancillary data were calibrated daily. Missing values are denoted with an entry value of -99. Logical_Consistency_Report: The discrete data were generated using certified reference materials to correct measured values and validate the quality of the data reported. Missing data were the result of either technological failure, or lack of data collection due to sampling design or inclement weather. Quality flags indicating the status of individual data points are as follows; Flag 0 = No quality control, Flag 1 = Good data, Flag 2= Probably good data, Flag 3 = Probably bad data, Flag 4 = Bad data, Flag 5 = Changed by analyst due to correction, Flag 9 = The value of the element is missing. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Lineage: Process_Step: Process_Description: Water sampling procedures, analytical methods, QAQC and data quality flagging procedures are described in Yates and others (2019).
