General Description
The Apollo ASP3 provides sea surface and atmospheric pCO2. An integrated SBE-45 thermosalinograph supports temperature and salinity correction, while the addition of 1-5 calibration gases ensures compensation with reference to known standards. Surface seawater travels through a showerhead equilibrator with a response time of 2 minutes. The equilibrated air is then dried and analyzed with an infrared or lased-based CO2 gas analyzer, the Li Cor LI-7815.

| SAMOS Data Category | |||||||||||||||||||||||||||||||||||
| Description | The corrected partial pressure of carbon dioxide in air at the temperature of equilibrium, derived from the mole fraction of CO2 in air. | The cooling pad temperature, used for diagnostic purposes. | The corrected partial pressure of CO2 in seawater at the temperature of the equilibrator. | The pressure of the equilibrator during measurement, used for diagnostic purposes. | The temperature of the water inside the equilibrator, used for diagnostic purposes. | Flow rate of gas through the system, used for diagnostic purposes. | The datetime associated with a GPS connected to the Apollo ASP3. For deployment on research vessels, this value can typically be ignored and may be null because GPS data are sourced from other equipment on the vessel. | GPS latitude is the latitude provided from a secondary sensor that is connected to the Apollo. Aboard research vessels, the ship's gps may or may not be piped into the Apollo. If gps_latitude data exist in the Apollo output, then it is representative of the ship position. | GPS longitude is the longitude provided from a secondary sensor that is connected to the Apollo. Aboard research vessels, the ship's gps may or may not be piped into the Apollo. If gps_longitude data exist in the Apollo output, then it is representative of the ship position. | Current mode of operation. Manual indicates that the sensor is being manipulated by a user. Auto indicates the sensors is performing its sampling routine. | Timestamp provided by the sensor with respect to the time found by the driving computer. This is used for diagnostic purposes. The preferred timestamp should be datetime_corrected provided by the network. | The cavity pressure of the LI-7815, used for diagnostic purposes. | The cavity temperature of the LI-7815, typical optical cavity temperature ranges from 52 to 58 degrees Celsius. If outside of this range the instrument may not be able to regulate the cavity temperature, used for diagnostic purposes. | Diagnostic code for the LI-7815. 0 = Normal Operation, 1 = Potential Noisy Measurements - Freq Adj, 2 = Potential Noisy Measurements - Laser Temp, 4 = Incomplete Scan, 8 = Potential Noisy Measurements - Startup Mode Finished, 16 = Potential Noisy Measurements - Startup Mode Init, 32 = Spectral fit RMS too high, 64 = Unregulated Pressure or Temp, 128 = Inlet Clogged, 256 = Not Ready. Invalid Measurements | Measurement of water vapor. | Raw measurement of the mole fraction of CO2 in dry air (xCO2), this measurement may represent air, water, or a standard calibration gas as the source. | Under the factory operating mode, the Apollo typically uses the last 10 values in a sampling run to provide a raw CO2 concentration. This value represents the standard deviation of those values and can be used for diagnostic purposes. | The measurement flow rate in air, in ml/min, for diagnostic purposes. | The interval for measurements of air reported in seconds. | The standard deviation of the measurements for each source collected. During normal operations a set of X readings are averaged and a standard deviation is provided. In the event readings are not within a standard deviation of 0.1 ppm this number may change. Used for diagnostic purposes. | The number of measurements for each source collected. During normal operations this is a set of X readings that are averaged and a standard deviation is provided. In the event readings are not within a standard deviation of 0.1 ppm this number may change. Used for diagnostic purposes. | The operator name or initials, used for diagnostic purposes. | Indicator if an overflow alarm is triggered, used for diagnostic purposes. | The flow rate of the purge cycle between different sets of measurements. | The amount of time purging occurs between samples and standards at the given purge flow rate. | Current analysis stream, consists of air, seawater, or standard gas. | In conjunction with the Apollo pCO2 system, this thermosalinograph measures flowthrough sea surface conductivity ranging from 0-7 S/m. Conductivity output from this TSG is used to derive salinity and further correct pCO2 data. | The partial pressure of carbon dioxide in seawater at the in-situ temperature using the equation of Takahashi et al. (2002) that utilizes the sea surface temperature measured at the ship's intake and the temperature measured at equilibration. | In conjunction with the Apollo pCO2 system, data is derived to produce flowthrough sea surface salinity in PSU. Salinity derived from this TSG is used to correct pCO2 data. | In conjunction with the Apollo pCO2 system, this thermosalinograph measures flowthrough sea surface temperature ranging from -5 to 35 degC. The difference between temperature measured at the Main Lab TSG and that of the temperature measured by the SBE-38 at the intake are used to correct for any temperature change due to residence time and further used to correct pCO2 data. | Indicator if a shutoff valve alarm is triggered, used for diagnostic purposes. | The type of test during the measurement, during normal operations the output will read continuous. Used for diagnostic purposes. | The flow rate of the water through the sensor, used for diagnostic purposes. | The water vapor pressure at equilibration calculated using the salinity and temperature values from the intake temperature and salinity. | The corrected xCO2 concentration derived from the raw equilibrator data output and measured and corrected CO2 concentration from standard gases. This applies to both seawater and air measurements. |

| Aug 02 2024 17:00:00 | Black, Ian | test | The Apollo ASP3 was turned on with seawater-air cycles only until the LDEO pCO2 system has the new calibration gas installed and is tested with satisfaction. | ||||
| Aug 02 2024 17:00:00 | Black, Ian | change of use level | Data collected by the Apollo prior to this timestamp and until another change in use level should be considered experimental and likely does not reflect natural changes. | ||||
| Jul 31 2024 18:01:00 | Black, Ian | software update | Users may recalculate bad air_pco2 from CORIOLIX output by using air xCO2, barometric pressure from a shipside source, and water vapor pressure calculated using the intake SBE 38 and SBE45. | ||||
| Jul 31 2024 18:00:00 | Black, Ian | software update | An issue with the air_pco2 value calculation was identified. The incorrect units were used for pressure. air_pco2 data prior to this timestamp are considered bad. A patch was pushed to fix this issue. | ||||
| Jul 30 2024 20:01:00 | Black, Ian | issue | The Apollo sampling routine has been disabled until we can determine the optimal standard sampling pattern and verify there are no more standard leaks. Priority is to keep the LDEO running. | ||||
| Jul 30 2024 20:00:00 | Black, Ian | issue | The 385ppm standard drained overnight. There is concern of a leak and that the Apollo may be drawing more standard than anticipated. The standards to the Apollo have been closed off. | ||||
