CO2/CLIVAR Repeat Hydrography Program CO2 Synthesis Science Team


Andrew G. Dickson (SIO)

RESEARCH OBJECTIVES AND SPECIFIC PLANS TO ACHIEVE THEM

The NOAA/NSF Repeat Hydrography CO2/tracer Program is a component of the Carbon Cycle Science Program (CCSP) and is a collaborative effort between NOAA and NSF to conduct a global decadal time-scale sampling of ocean transports and inventories of climatically significant parameters. It provides a core set of carbon and tracer measurements and anticipates that additional carbon/CLIVAR measurements will be added to the cruises on an “as required” basis. The sequence and timing for the sections takes into consideration the CCSP objectives, and considers the timing of national and international programs. The new data from this program needs to be synthesized into a globally consistent data set (e.g., corrected for analytical errors and systematic biases) and combined with similar data sets from our international partners working on this same problem.

The CO2 Science Team has been formed to meet these goals. It meets at least once a year, and corresponds in between meetings working to ensure that the surveys are carried out in an efficient manner, and that the data obtained are consistent and correct.

RESEARCH ACCOMPLISHMENTS

The Science Team funded by this grant (Project Director, Dr. R. Feely, NOAA/PMEL) met in Miami, FL on February 7–8, 2007, where preliminary results from the program, as well as planning for the coming years, were discussed. In addition, the team has continued discussions of data archival and planning for the preparation of publications. Since that time, Dr. Dickson has continued to work on ensuring data from his SIO group is in the appropriate form for public release. An additional task carried out as part of this work is working with Dr. C. Sabine (NOAA/PMEL) to revise the 1994 DOE Handbook of measurement techniques for oceanic CO2 measurements. This should be published towards the end of 2007.
