Figures 8 and 9 show a comparison of the traces obtained by the electronic 

 BT's with the corresponding standard Nansen cast and 900 foot mechanical 

 BT. A statistical analysis of the electronic BT data collected on this 

 cruise will be made as compared to other methods of temperature -depth 

 measurements. Data collected from future tests will likewise be analyzed, 

 and from these results a final design will be selected. Figure 10 

 shows the WHOI electronic BT and Figure 11 shows the HYDRO linear electronic 

 BT. 



IV. OCEANOGRAPHIC AND METEOROLOGICAL OBSERVATIONS 



This section is a resume of the kind and quantity of data obtained. 

 These data are tabulated in the Appendixes as indicated below. 



A. TEMPERATURE DATA 



The following methods were used to obtain temperature with depth 

 data. In general, when two or more instruments were used simultaneously, 

 the data agreed well. 



1. Mechanical 900' BT's - 801 BT's were obtained to an average 

 depth of 840 feet. The data, 24360 data points, are presented in 

 Appendix II. 



2. Hydro electronic linear BT - 14 traces down and 

 14 traces up were plotted by the X-Y recorder. 



3. WHOI electronic BT - 19 traces down and 19 

 traces up were plotted by the X-Y recorder. 



4. Thermistor Chain - Approximately 24 hours, or 15,440 data 

 points, of continuous data were recorded. The data have not been completely 

 reduced at this time. 



5. Reversing thermometer - 645 data points were obtained and 

 are presented in Appendix III. 



6. Thermal array - Approximately 26 hours of continuous data 

 were recorded on two 12-point Brown recorders. However, only 17 hours of 

 the data are considered useful and the data taken at the 700' depth are 

 presented in Appendix IV. Data from all sensors total 61,200 data points. 



B. SEA AND SWELL 



Visual observations were made every 15 minutes. Approximately 1/2 

 hour of Splashnik data was recorded on magnetic tape. 



C. CURRENTS 



Eighty-seven current profiles at seven depths were obtained, repre- 

 senting 616 data points. The data are presented in Appendix V.
