CCS - CCS_OA_07 Mooring data May 2018 deployment

\t\n\nProject Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.\n\n--o--\n\nDescription:\n\nMeasurements are made Seabird Seaphox (for dissolved oxygen, pH, Seawater Temperature and Salinity), mounted on a lander. The Seaphox takes a reading every hour in the UTC hour and is transmitted real time through acoustic and/or 3G modems. The Seaphox consists of a SeaFET (pH) and SBE-37-SMP-ODO CTD (SW temperature, Salinity and Dissolved Oxygen [SBE63]).\n\nRelevant component details: make, model, serial number, firmware version, settings:\n\nSensor | Make | Model | Serial Number | Calibration\n\nfCO2 sensor | Battelle | 192 | Pre and post deployment calibration; Continuous (see below).\n\npH | Seaphox | SeaFET | 1003 | 2017-05, factory calibrated, verified by CSIRO lab\n\nDO | Seabird | SBE-37-SMP-ODO | 15643 | as above\n\nT and S | Seabird | SBE-63 | 1697 | as above\n\nCalibration Information (if applicable)\n\nBattelle:\n\nThe LI-COR 820 in the Battelle pco2 sensor response is checked before and after each deployment using a range of CO2-in-air reference gases (0, 260, 370, 450 micromol/mol) at CSIRO, Hobart. The sensor measurement using factory calibrations for the LI-CO2 820 is typically within 1 micromol/mol of the reference gas value. If the LI-COR 820 measurements and the CO2-in-air reference gas values are different by more than 2 micromol/mol, a correction is applied to Li-CO2 820 output based the reference gas values. A seawater bath operated over a range of temperatures and CO2 expected in the field is then used to check the MapCO2 system (equilibrator and LI-COR 820 measurement) against a General Oceanics 8050 CO2 sensor to ensure the systems agree within 2 micromol/mol. Pressure measurements are made using the LI-COR 820 pressure sensor, checked against a Druck DPI142 pressure indicator and verified to agree within 0.5 kPa before and after each deployment.\n\nSeaphox:\n\nSBE 37 (T, S, DO) and the SeaFET (pH) are calibrated by the factory and verified in the CSIRO laboratory. The pH reported in the files is flagged questionable for the pre-deployment calibrated data due to possible calibration changes which can occur after deployment\n\npH (calibrated) is further processed after the recovery using in situ bottle sample where available, using Total Alkalinity (TA) and Dissolved Inorganic Carbon (DIC), which will be converted to pH using CO2SYS, where the Lueker k1k2 dissociation constant is used.\n\nLocation: -38.2382, 147.4517
