 HYDROGRAPHIC FIELD REPORT 



by 

 Commander David C. Nutt, USNR 



A principal part of the 1952 project was the carrying out of reconnaissance survey 

 operations in the area from Port Manvers to Saglek Bay, an area where little actual 

 sounding work had previously been done. Approximately 1500 miles of controlled sound- 

 ing lines were run in this area with the purpose of making a preliminary development 

 of the general bottom topography of the area with a more detailed examination of the 

 approaches and runs more generally used and suitable for navigation. 



While in this area and while travelling along the coast examination was made of 

 the Sailing Directions and corrections and additions prepared as practicable. 



Soundings were made from the Blue Dolphin with an NJ-9 recording fathometer; and 

 control was established by bearings of peaks and tangents and by sextant angles. In 

 addition soundings close inshore in certain areas were made from the Blue Dolphin 

 launch which was equipped with an NK-7 portable recording fathometer. 



These reconnaissance survey data will be prepared and submitted to the U. S. 

 Navy Hydrographic Office for analysis and further dissemination.
