As XBT probes Sippican "Deep Blue" only were launched. The 
specification given by the manufacturer is as follows: 
Temperature:

-2 °C to 35.5 °C 
± 0.2 °C 
to 0.01 °C 
Range

to 760 m 
± 2 % of depth 
65 cm 
Owing to the fact that the probes were deployed from the wing 
of the navigation bridge (height: 30 m) a depth accuracy in 
fluencing effect should be expected (Krause, 1986), however, 
its quality cannot be given. 
To date, no sea surface temperatures are measured indepen 
dently aboard CMS "Koln Atlantic" as a reference. Thus, for 
the WOCE field phase it is hoped to install a thermometer 
within the ship at the ship's side, equipped with a display 
on the navigation bridge. Furthermore, a vertical extension 
of measurements down to 1500 m is planned.
