Table 3: Profiles 0 to 163 for float #WMO 3900526 with flags 3 or 4, and proposition of modifications.
Comments :
This float has been controled in delayed-mode in 2010 for its profiles from 0 to 67, and flags onits profiles 1, 3, 10, 46 and 61 have been yet modified.
For this Provor-CTS3, the resolution is equal to 10 dbar from the surface to 800 dbar, then 25dbar from 800 to 2000 dbar. Salinity data between 0 and 10 dbar are acquired when the pump ofthe CTD is turned off, and may be thus suspicious.
