| log in | [High-Frequency CO2-system observations from a moored sensor in the York River] - (Collaborative Research: Multiple Stressors in the Estuarine Environment: What drives changes in the Carbon Dioxide system?) | These are CO2-system data from a moored sensor in the York River, a tributary of the Chesapeake Bay. Temperature, salinity and pH were acquired hourly over two deployments lasting several months. Sensor data were then averaged to 24-hour resolution. Data were calibrated with discrete dissolved inorganic carbon (TCO2) and alkalinity samples analyzed at the Virginia Institute of Marine Science, following standard procedures. The pH sensor data were then combined with salinity data, and a relationship between alkalinity and salinity, to compute the remaining CO2-system parameters (TCO2, CO2 partial pressure (pCO2), and saturation state of aragonite. There is one file for each deployment (D1, and D2); the data are in a comma-separated (csv) format. Hourly measured temperature, salinity, and pH are given, as well as derived alkalinity, TCO2, pCO2, and saturation state of aragonite are included. Units are in the first row of each file.\n\ncdm_data_type = Other\nVARIABLES:\nDate_Matlab (unitless)\ntime (Datetime, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nTemp_degC (degrees Celsius (°C))\nSalinity (unitless)\npH_total (unitless)\nalkalinity_umol_kg (micromole per Kilogram (umol/kg))\nTCO2_umol_kg (micromole per Kilogram (umol/kg))\npCO2_uatm (microatmospheres (uatm))\nWar (unitless)\nDeployment (unitless)\n | BCO-DMO | bcodmo_dataset_890566_v1 |
