Oceanic Carbon Dioxide
Quality Control

Research Group

The goal of our program is to provide a mechanism for the quality control of oceanic carbon dioxide measurements by providing investigators making such measurements with the following:

Reference materials for the measurement of total dissolved inorganic carbon and total alkalinity that are based on sterilized natural seawater. A well-written set of standard methods that can be used for the various analyses (the DOE Handbook of Methods - published by CDIAC). Organization of collaborative studies and between-laboratory method comparisons to enable laboratories to assess the present quality of their measurement techniques. A bibliography of articles produced by us detailing work carried out in support of this program is provided.

Main Staff

George Anderson (gcanderson@ucsd.edu)
Staff Research Associate: George is responsible for the coulometric analyses of acid (used for alkalinity determinations) that are done both for our laboratories as well as for others. In addition, George performs some of the alkalinity measurements used for certification.

Guy Emanuele (gemanuele@ucsd.edu)

Staff Research Associate (Keeling Carbon Dioxide Research Group): Guy performs the extractions of the reference material bottles that are used to certify the various batches, and also measures the amount of CO2 produced using an electronic constant-volume manometer (ECM).

Katy Piper (co2crms@mpl.ucsd.edu)
Administrative Assistant: Katy is responsible for shipping reference materials to the end users around the world. She keeps track of all the documentation relating to the various batches as well as being our liason with Dr. Keeling's laboratory where the analyses for total dissolved inorganic carbon are performed.
