Time Series of Autonomous Carbonate System Parameter Measurements in Middle Tampa Bay, Florida, USA

June 7, 2022

This data set contains time series measurements of carbonate system parameters including water temperature (degrees C), pressure (dbars), salinity, pHT (pH on the total scale), carbon dioxide (ppm), dissolved oxygen (milligrams/L), and photosynthetically active radiation (microEinsteins). These data were collected in Middle Tampa Bay, Florida, by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center using an autonomous instrument package called the Ocean Carbon System version 2 (OCSv2). The OCSv2 consists of four sensors integrated using a Satlantic Stor-X data logger including a Satlantic SeapHOx pH sensor, a Sea-Bird SBE 37-SMP-ODO MicroCAT C-T-ODO (P) Recorder, a Pro-Oceanus CO2-Pro CV sensor, and a Wetlabs Eco-PAR sensor. Each parameter was measured hourly over multiple twenty-four hour time periods, ranging from weeks to months.
