VARIABLES / PARAMETERS:
| Dissolved Inorganic Carbon | |
|---|---|
| Abbreviation: | TCARBN |
| Unit: | UMOL/KG |
| Observation type: | Discrete, profile, bottle |
| Measured or calculated: | Measured |
| Sampling instrument: | Niskin Bottles |
| Analyzing instrument: | VINDTA CT system |
| Detailed sampling and analyzing information: | Samples preserved with HgCl2 and measured in the lab December 2012 over three days using a VINDTA CT system with colometric end point detection. |
| CRM manufacturer: | Andrew Dickson Laboratory at SIO |
| CRM batch number: | CRM batch 116 and 113. |
| Preservation method: | mercuric chloride solution |
| Uncertainty: | The values were corrected using one correction factor for each day, based on the average value of CRM analyzed at the start and end of each cell. The correction corresponded to 5-8 umol/kg. Precision evaluated from the two CRMs analysed each day, better than 2 umol/kg |

| Total alkalinity | |
|---|---|
| Abbreviation: | ALKALI |
| Unit: | UMOL/KG |
| Observation type: | Discrete, bottle |
| Measured or calculated: | Measured |
| Sampling instrument: | Niskin Bottles |
| Analyzing instrument: | VINDTA system |
| Type of titration: | Gran titration |
| Cell type (open or closed): | open |
| Detailed sampling and analyzing information: | Analysed on water left over from CT analyses using Gran titration on a VINDTA system, this took 4 days of December 2012. The titrations were carried out before final salinity data were ready and salinity == 35 was assumed. The TA, reported here, was recalculated from the titration data when final salinty values became available. |
| CRM manufacturer: | Andrew Dickson Laboratory at SIO |
| CRM batch number: | CRM batch 116 and 113 |
| Preservation method: | Mercury chloride |
| Uncertainty: | Corrections corresponded to around 20 umol/kg. Precision evaluated from the two CRMS measured each day, better that 2 umol/kg. |
