Data provided is from a trailing thermistor with bucket measurements.   
The thermistor data has been calibrated but not quality controlled.   
There were 4 sensors deployed, the first was deployed for the whole 
of the first leg and had drifted by approximately 0.3 degC by the port 
call but seemed stable at this value.   The thermistor was out of the 
water whilst the ship was steaming,  hopefully all this data has been 
removed from this data set  (but may not all have been deleted).
