Ship Codes & Quality Codes

Ship codes
The ship code appearing in the ASCII data file may be used to facilitate along-track filtering of the data, as well as for detecting potential errors associated with a given voyage. The ship codes are:

Ship Code	Ship Name
Alis	R/VAlis
Atal	R/V l'Atalante
Chal	Challenger
Expl	Explorer
Lady	Lady Geraldine
Yeye	Yewene Yewene
Mari	Mariner
Rons	Ronsard
Noro	R/V Le Noroit
Rimb	Rimbaud
Voya	Voyager
Pais	Pacific Islander
Thom	Thomson
Suro	R/V Le Suroit
Prov	Providence
Khib	Kyowa Hibiscus
Ante	R/V l’Antea
Wash	Washington
Kcat	Kyowa Cattleya
Lond	London
Rome	Rome
Kaim	R/V Ka’ Imimoana
Arst	Argentina Star
Mira	R/V Mirai
Robr	R/V Ron Brown
Cois	Coral Islander

Quality code
The quality code appearing in the data file is based on the utilisation of various criteria used to detect, delete or correct dubious measurements. The seven quality codes are as follows:

Code 1: visual detection/correction of errors
Code 2: Code 1 + comparison with climatological mean and standard deviation.
Code 3: Code 2 + utilisation of simultaneous water samples and/or CTD measurements
Code 4: Code 1 + utilisation of the pre/post calibration coefficients of the sensors
Code 5: Code 2 + utilisation of the pre/post calibration coefficients of the sensors
Code 6: Code 4 + utilisation of simultaneous water samples and/or CTD measurements
Code 7: Code 5 + utilisation of simultaneous water samples and/or CTD measurements
