CTD; Calibration; IntercalibrationAbstract
A series of laboratory intercalibrations of a CTD system were undertaken between 1986 and 1990 as part of cooperative
research program between the United States (US) and People's Republic of China (PRC). A comparison of US and PRC calibration
facility standards is carried out using a NBIS/EG&G Marine Instruments Mark IIIb CTD system as a "quasi-transfer standard."
When compared with the quoted accuracy of the calibration facilities, pressure was found to be more accurate and temperatue was
about as accurate as stated. The conductivity standard differences between facilities are difficult to assess because of the CTD
conductivity sensor drift.
