README FOR SKOGAFOSS CRUISE AOML_SKO713 The electronic data in comma delimited ASCII form (.CSV) can be found at: http://www.aoml.noaa.gov/ocd/gcc/ ****************** Use of AOML CO2 Underway Data ************************** * [Adapted from NOAA Earth System and Diagnostic Laboaratory (ESDL) * ************* Carbon Cycle Greenhouse Gasses (CCGG) web site] ************* These data are made freely available to the public and the scientific community in the belief that their wide dissemination will lead to greater understanding and new scientific insights. The availability of these data does not constitute publication of the data. We rely on the ethics and integrity of the user to assure that AOML receives fair credit for our work. Please send manuscripts using this data to AOML for review before they are submitted for publication so we can insure that the quality and limitations of the data are accurately represented. *********************** Reciprocity Agreement ***************************** * [Adapted from NOAA Earth System and Diagnostic Laboaratory (ESDL) * ************* Carbon Cycle Greenhouse Gasses (CCGG) web site] ************* Use of these data implies an agreement to reciprocate. Laboratories making similar measurements agree to make their own data available to the general public and to the scientific community in an equally complete and easily "accessible form. Modelers are encouraged to make available to the community, " "upon request, their own tools used in the interpretation of the AOML data," namely well documented model code and any additional information necessary for other scientists to repeat the work and to run modified versions. *************************************************************************** For a full description of the instrumentation and procedures, see the MASTER README file accessible thru the MASTER README link located in the left navigation bar of the Skogafoss web pages. Class of data: Surface ocean carbon dioxide concentrations Dataset identifier: AOML_SKO713 Cruise Dates: 30 Mar, 2007 - 15 Apr, 2007 Measurement platform identifier: M/V Skogafoss Scientists responsible for technical quality of this dataset: Rik Wanninkhof Rik.Wanninkhof@noaa.gov Denis Pierrot Denis.Pierrot@noaa.gov Kevin Sullivan Kevin.Sullivan@noaa.gov Timestamp for initial submission of dataset: 14-November-07 Timestamp for most recent update of dataset: 14-November-07 The following gas reference standards were used for this cruise: From October 24, 2006 to present STANDARDS/CONC TANK # Std 1 197.74 fa02271 Std 2 453.77 ja02299 Std 3 373.20 ja02282 Std 4 249.51 fa02450 Comments: The temperature reading in the equilibrator occasionally was not read. For these single data records the preceding and following values were averaged. The response of the water channel was drifting negative, which is estimated to add an uncertainty of ~2 ppm in the reported CO2 concentrations.
