rently with 1 5 1 bucket temperatures. XBT surface temperatures, corrected for the XBT 

 system error, were compared with the bucket temperatures. The results of these com- 

 parisons are summarized in figure 1 1. On the average, the bucket temperatures were 

 0.04°C, with a standard deviation of 0.10°C, which was higher than the corrected XBT 

 surface temperatures. The differences varied from -0.22°C to 0.24°C. 



During RAPLOC/DEEPTOW CTD/SV, surface temperatures were measured 

 concurrently with 1 1 bucket temperatures. These comparisons showed that the bucket 

 temperatures were higher than the CTD/SV measured temperatures. The average of the 1 1 

 comparisons was 0.07°C, with a standard deviation of 0.05°C. 



It is concluded that the CAPER bucket thermometer errors were -0.04° C for both 

 the MOANA WAVE and DE STEIGUER thermometers, and that the RAPLOC/DEEPTOW 

 bucket thermometer error was -0.07°C.
