THIRD CRUISE, "TAMPA," APRIL 24-MAY 8 



The Tampa relieved the Modoc at 11 a. m,, April 24. The oceano- 

 graphic party was received on board, the transfer being effected in a 

 moderate sea. The vessel then stood to the northeastward to search 

 for bergs reported on April 22. On April 25 an intermittent fog 

 being encountered, the Tampa was hove to until midnight when the 

 cruise was again continued. During one of the clearings the French 

 barkentine Annie Cannes was passed close aboard and given her 

 position. A moderate NW. wind was encountered shortl}'- after 

 getting under way which increased to a force of eight and continued 

 blowing during the 26th, 27th, and part of the 2Sth, when it came 

 out from the northward and northeastward with a dense fog which 

 lasted until 10 p. m., April 29. During this time the vessel was 

 practically hove to, but worked very slowly toward the scene of the 

 southernmost ice. 



On the morning of April 29 during a fog a small berg was sighted 

 in latitude 45° 49' N., long. 46° 58' W. As the vessel approached 

 the berg, which consisted of two large pinnacks, it capsized, break- 

 ing into a number of dangerous growlers. This proved to be a part 

 of the large berg later sighted by the Tampa. The search for ice 

 continued and at 11.30 a. m. on the 30th a large berg was found in 

 latitude 45° 58' N., longitude 46° 57' W. This was immediately 

 recognized as No. 7 of the first bergs seen by the Modoc on April 

 22. It was remarkable how little change had occurred during the 

 interval of time that had elapsed, there being no noticeable reduc- 

 tion in size, no old water lines visible, and no new ones formed. 

 This was due no doubt to the fact that the berg had remained in 

 the cold Arctic water until this time and that the temperature of the 

 air was such as not to permit melting or disintegration. Station 

 No. 33 was taken near this berg later on in the day but no Arctic 

 water was found. On the contrary a rise in temperature was 

 noticed shov/ing the rapidity of the invasion of the warmer water 

 from the southward. During the night of April 30, berg No. 7 con- 

 tinued in the eddy of warm water and was carried northwestward 

 and returned to the cold water. It had not changed in shape or size 

 when first observed, but 15 hours later while in the warm water had 

 capsized and commenced disintegrating rapidly. While standing by 

 this berg a report was received from a steamer stating that a large 

 iceberg was seen in latitude 45° 38' N., longitude 48° 51' W. The 

 Tampa proceeded at 3.50 a. m., May 1 for this position. At 9.30 

 a. m. the position was reached but no ice was sighted. The area 

 was thoroughly searched but nothing was seen. At 12 noon a report 

 was received from a steamer stating that a large berg had been 

 sighted in latitude 45° 05' N., longitude 48° 32' W. A course was
