Carbon Dioxide and Hydrographic Data Obtained During the MP (MANTRA/PIRANA) Cruises in the Pacific Ocean in 2002-2003 (NCEI Accession 0108077)

INVESTIGATOR:
Patricia L. Yager - UGA

PACKAGE DESCRIPTION: This dataset discrete profile chemical and physical data collected from R/V Ka'imikai-O-Kanaloa, R/V Kilo Moana and R/V Roger Revelle in the North Pacific Ocean from 2002-07-01 to 2003-08-21 during the MP-5, MP-6 and MP-9 cruises. These data include total alkalinity, dissolved inorganic carbon, salinity and temperature. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement. These data were collected by Patricia L. Yager of University of Georgia; School of Marine Programs as part of the MP-5 cruise, MP-6 cruise and MP-9 cruise data set.

VARIABLES / PARAMETERS:

Dissolved Inorganic Carbon
Abbreviation: DIC
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Calculated
Detailed sampling and analyzing information: Samples stored cold and dark and returned to UGA for analysis. Samples analyzed using a SOMMA (Single Operator Multi-Metabolic Analyzer) connected to a CO2 coulometer (UIC, Inc) interfaced to a PC. See Johnson et al., 1993; 1998.
Standardization description: The instrument was first calibrated using a standard CO2 gas (99.999%). Certified Reference Material (Dickson 2001) was run twice at the start of every day, after every ten samples, and at the end of the day. Unless daily drift was detected (rare), then we computed the average CRM for the day, calculated the ratio of the expected CRM value to the measured value, and multiplied all the data by this ratio. In the rare case of drift, we corrected to the nearest CRM.
CRM batch number: 55 58
Total alkalinity
Abbreviation: TA
Observation type: discrete
In-situ / Manipulation / Response variable: In-situ observation
Measured or calculated: Measured
Type of titration: Potentiometric titration using an automated burette with 0.1N HCl in 0.7 M NaCl
Cell type (open or closed): Open
Curve fitting method: Calculated using the modified gran approach (Dickson et al., 2003)
TA blank correction: none used
Uncertainty: CRMs were used as primary alkalinity reference standards to back calculate titration acid concentration. This forced the absolute accuracy of samples to CRM standards. Instrument precision (sR, based on duplicate runs of each CRM; n=15) = 1.48 ueq/kg. Sampling precision (sR, based on duplicate samples collected in series from the same Niskin bottle; n=18) = 1.55 ueq/kg.
