PACKAGE DESCRIPTION: This dataset includes discrete, profile, physical and chemical data collected during the R/V Melville CLIVAR Repeat Sections cruise P02 (EXPOCODE 318M200406) in the North Pacific Ocean and Philippine Sea from 2004-06-15 to 2004-08-27. These data include Dissolved inorganic carbon (DIC), total alkalinity (TA), temperature, salinity, oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12, CFC113), dissolved organic carbon (DOC), Chromophoric Dissolved Organic Matter (CDOM), delta carbon-13, delta carbon-14, helium, neon and tritium. The instruments used to collect these data include Alkalinity titrator, coulometer for DIC measurement, CTD, niskin bottles and others. These data were collected by Dennis Hansell of Rosenstiel School of Marine and Atmospheric Science, Andrew Dickson of Scripps Institution of Oceanography and Richard A. Feely of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the CLIVAR_P02_2004 data set. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

Replicate information: |
Over 2700 samples were analyzed for DIC; full profiles were completed at even numbered stations, with replicate samples taken from the surface, oxygen minimum, and bottom Niskin-type bottles. On the odd numbered stations, samples were drawn throughout the upper 1200m; on three occasions were only surface replicates drawn due to equipment problems, resulting in a backlog of samples. All replicate samples were run at different times during the station analysis for quality assurance of the integrity of the coulometer cell solutions. No systematic differences between the replicates were observed. In addition, samples were drawn from the underway seawater system, generally one to two times daily. |
Standardization description: |
The coulometers were each calibrated by injecting aliquots of pure CO2 (99.995%) by means of an 8-port valve outfitted with two sample loops. The instruments were calibrated at the beginning, middle, and end of each station with a set of the gas loop injections. |
