nitude as in the cases of other meanders which have been charted 

 from thne to time. It is, of course, difficult to make an accurate 

 estimate of the distance moved but the rate of progression of this 

 meander would seem to have been about 2 or 3 miles per day whereas 

 others have usually moved about 4 miles per day in this part of the area. 

 The volume of flow, mean temperature and heat transport of the 

 Labrador Current have been determined for each of 19 sections occu- 

 pied during the 1952 season and postseason cruises. Some of these 

 sections have been occupied in other years and m the case of three 

 sections, T, U, and W, numerous occupations in earlier years have 

 provided a rough approximation to seasonal normals. The locations 

 of sections T, U, and W are as follows: Section T extends south- 

 easterly from about 46°20' N., 49°00' W.; section U extends eastward 

 from the Grand Banks at about the 45th parallel; and section W ex- 

 tends southward from the Grand Banks at about the 50th meridian. 

 The tentative normal seasonal variations in the Labrador Current at 

 these sections have been given in bulletin number 36 of this series. 

 Although little is known of the seasonal variation in the Labrador 

 Current off South Wolf Island, Labrador, this section has been occu- 

 pied once during each of 15 summers between 1928 and 1952 and 

 average values at this section have been used for comparison with the 

 results obtained in 1952. An insuflScient number of earlier occupa- 

 tions of the Bonavista triangle sections and sections F, G, and H, 

 intermediate between the triangle and Flemish Cap, are available for 

 derivation of even average values for these sections. 



Values found in 1952 are summarized in table 1 in which they are 

 compared with such normal values as are available. In this table, as 

 well as in the followmg discussion the volume transport is given in 

 millions of cubic meters per second, the mean temperature and mini- 

 mum observed temperature are given in degrees centigrade, and the 

 heat transport is given in millions of cubic meter degrees centigrade 

 per second. 



It will be noted that the volume of flow of the Labrador Current in 

 the Grand Banks region was subnormal in both the second and thnd 

 surveys with the largest anomaly occuring at section W. The partial 

 recovery at section T between the second and third surveys was 

 accompanied by a larger diversion of this water southward of that 

 section. This diversion, accomplished by the sahent of Atlantic 

 Current water also showed up in the mean temperature in which the 

 anomaly changed from negative to positive values. The minimum 

 temperatures were not as cold as normal in either survey. 



Northward of Flemish Cap there was an increase in volume of flow 

 at section G between the first and second surveys and very little 

 change between the second and third surveys. The volume transport 

 across the northwest section of the Bonavista triangle showed a marked 

 mcrease between the first cruise and the post-season cruise, although
