CCS - CCS_SF_01 Mooring data May 2018 deployment

Full description

Project 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.

Description:

Measurements 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]).

Relevant component details: make, model, serial number, firmware version, settings:

Sensor | Make | Model | Serial Number | Calibration

pH | Seaphox | SeaFET | 444 | 2017-05, factory calibrated, verified by CSIRO lab

DO | Seabird | SBE-37-SMP-ODO | 15557 | as above

T and S | Seabird | SBE-63 | 1683 | as above

Calibration Information (if applicable)

SBE 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

pH (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.
