PACKAGE DESCRIPTION: This dataset includes profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, temperature, salinity, oxygen and CFCs obtained during R/V Oden Lomonosov Ridge off Greenland (LOMROG) expedition (EXPOCODE 77DN20070812) in the Arctic Ocean from 2007-08-12 to 2007-09-19. The R/V Oden expedition is the oceanographic component of LOMROG focuses on constraining and understanding the pathways of the Atlantic water and deep water across the Lomonosov Ridge between the Eurasian Basin and Canadian Basin and through the western Fram Strait.

VARIABLES / PARAMETERS:
| Dissolved Inorganic Carbon | |
|---|---|
| Abbreviation: | TCARBN |
| Unit: | UMOL/KG |
| Observation type: | Discrete, bottle |
| Measured or calculated: | Measured |
| Sampling instrument: | coulometric titration method |
| Analyzing instrument: | SOMMA |
| Detailed sampling and analyzing information: | Total dissolved inorganic carbon (DIC) was determined by a coulometric titration method having a precision of ~1 µmol kg-1, with the accuracy set by calibration against certified reference materials (CRM), supplied by A. Dickson, Scripps Institution of Oceanography (USA) |
| Preservation method: | mercuric chloride solution |
| Preservative volume: | 100 mL |
| Uncertainty: | precision was better than 2 micromol kg-1 |
| Quality flag convention: | WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value |
| Researcher name: | Leif Anderson |
| Researcher institution: | University of Gothenburg |
| Total alkalinity | |
|---|---|
| Abbreviation: | ALKALI |
| Unit: | UMOL/KG |
| Observation type: | Discrete, bottle |
| Measured or calculated: | Measured |
| Type of titration: | potentiometric titration |
| Cell type (open or closed): | open |
| Detailed sampling and analyzing information: | Total alkalinity (ALKALI) was determined by potentiometric titration, precision ~1 µmol kg-1, with the accuracy set the same way as for DIC. |
| Quality flag convention: | WOCE quality control flags are used: 2 = good value, 3 = questionable value, 4 = bad value |

| pH | |
|---|---|
| Abbreviation: | PH_TOT |
| pH scale: | Total Scale |
| Observation type: | Discrete, bottle |
| Measured or calculated: | Measured |
| Sampling instrument: | Niskin Bottles |
| Detailed sampling and analyzing information: | The determination of pH was performed by the use of a diode-array spectrophotometer using a sulphonephtalein dye, m-cresol purple, as indicator and measured in a 1 cm flowcell thermostated to 15 C (pH15). The precision and accuracy for the pH15 measurements were +/- 0.0005 and +/- 0.002 pH units, respectively. |
