EIGHTH CRUISE, "MODOC," JULY 9-12 



The Modoc took up the patrol at 8 a. m., July 9. A course was set 

 for the northwest corner of the unsearched area, at a speed to bring 

 the vessel up with the area shortly before daylight on the 10th. As a 

 "high" was due in the area to be searched, the Modoc increased her 

 speed to take advantage of all the good weather. 



wSearch by rectangular method was begun at 5 a. m. of July 10 

 under ideal conditions, with clear skies and highest visibility, and was 

 continued until sunset. The last portion of the ex]>]ored area be- 

 tween rarallels 42° 00' and 44° 00' and between meridians 49° 30' 

 and 52° 00' was covered on July 11 and the patrol commander noti- 

 fied at Halifax by radio, through Cape Race and Camperdown, at 

 3 p. m., forty-fifth meridian time, that the search had been com- 

 pleted. 



At 8 a. m., forty-fifth meridian time, of July 12 advice was received 

 from the patrol commander that the International Ice Patrol was 

 discontinued for the season, and this infoimation was transmitted 

 by broadcast from the Modoc to all vessels and stations as of noon, 

 Greenwich civil time. 



Junction was made with the Tampa at 5.30 a. m. on the 15th in 

 latitude 42° 30' N., longitude 65° 23' W., where transfer of the 

 oceanographic ] arty was effected to that vessel. From this point 

 the Modoc proceeded for her station at Wilmington, N. C, and the 

 Tampa ])roceeded to Boston, Mass. 



During this cruise of the Modoc only 75 teni] erature reports were 

 received from steamei-s. This was far below the average and is 

 probably explainable by the belief on the j^art of many that the 

 necossit}' for the reports had passed. 



No ice was seen or reported during the cruise. Seven requests 

 for information regarding the ice situation weie received and one 

 request for medical advice. Two rej)orts of drifting wj-eckage were 

 received and forwarded to the Hydrograrhic Office. 



The weather experienced during this cruise was very good, encoun- 

 tering no gales and very little fog. (See Charts Nos. 15 and 16.) 



There was a remarkable change of temperature during this cruise. 

 The characteristic southeast tongue still existed, l)ut was much 

 smaller. No water below 42° was found south of latitude 47° 00'. 

 The Banks water became uniformly warmer, reaching as high as 

 56°. The Arctic water had completely disaj^] eared. (See Chart 

 No. 15.) 



Messages of appreciation were transmitted to various land radio 

 stations for assistance rendei-ed bv theni during the season.
