plified volume flow computations through sole- 

 noids located along the bottom in shallow water. 

 The volume flow computed has the dimensions 10 G 

 m 3 /sec and the direction of flow is indicated by a 

 plus or minus sign. Thus, each vertical property 

 section is divided into solenoids and the entire vol- 

 ume flow, magnitude, and direction, through the 

 section is determined. 



Property transport of heat and salt are com- 

 puted for each solenoid in the section using the 

 following equations : 



where 



and 



where 



Qt=VXT m (5) 



Q\ =heat transport (10 6 °C. m 3 /sec) 



T m = mean temperature within solenoid 



(°C) 

 V= volume flow (10 6 m 3 /sec) 



M s =VxS m X Pm (6) 



M s =salt transport (10 9 ) gms/sec 

 S m = mean salinity within solenoid 

 p m =mean density of seawater=1.03 

 gms/cm 3 



The processed temperature and salinity data 

 were recorded on form NHO-NODC-31/67/1 

 (9-61), Physical and Chemical Data forms for 

 Oceanographic Stations, and delivered to the Na- 

 tional Oceanographic Data Center (NODC). The 

 interpolated temperatures and salinities for stand- 

 ard depths, sigma-t, specific volume anomalies, 

 geopotential anomalies (AD), and sound veloci- 

 ties were made by NODC and NODC provided 

 listings for the preparation of tables (I-V). 



CRUISE NARRATIVES 



During the 1964-66 period, a total of 22 whole 

 or in part occupations were made on six of the 

 Standard Sections. The cruise number, ships, dates, 

 numbers of stations and NODC accession numbers 

 for these cruises are given in table 1. Section 7 was 

 not occupied during this period, but has been in- 

 cluded in the program in 1967. 



Five of these cruises were made by ocean station 

 vessels returning from Ocean Stations BRAVO 

 and CHARLIE. The data were obtained on these 

 cruises entirely by Nansen bottle casts. The re- 

 mainder of the cruises were made by the U.S. 

 Coast Guard Oceanographic Vessels, the USCGC 

 EVERGREEN and USCGC ROCKAWAY. 



Cruise Al-1 by the USCGC EVERGREEN 

 was part of an oceanographic survey in the west- 

 ern Labrador Sea in the vicinity of Hudson Strait 

 in 1965. The purpose of the survey was to quantita- 

 tively determine the contribution to and the effect 

 of the Hudson Strait outflow on the Labrador 

 Current. The data are published in the U.S. Coast 

 Guard Oceanographic Report No. 12, "Ocean- 

 ography of the Labrador Sea in the Vicinity of 

 Hudson Strait in 1965," Kollmeyer, et al., 1967. 



Cruises A3-1 and A3-2 were accomplished by 

 the USCGC MENDOTA and the USCGC ING- 

 HAM en route to and on the return voyage from 

 Ocean Station CHARLIE, respectively. The data 

 from both these cruises are listed by NODC as 

 Ref. No. 31-223 and as table I of this report. 



Cruises Al-2, A2-2, A3-5 through A3-9, A4-1, 

 and A4-2 were made by the USCGC EVER- 

 GREEN in support of International Ice Patrol 

 research. They were made during the ice season 

 of 1966 and consisted of a quasi-synoptic occupa- 

 tion of sections 2, 3, and 4 between 2 April and 8 

 April 1966 and then a time-series study of section 

 3 between 16 April and 21 April of three nearly 

 complete occupations. During May-June 1966, 

 the USCGC EVERGREEN then reoccupied sec- 

 tions 1, 2, 3, and 4 to investigate the temporal vari- 

 ations in the circulation of the Labrador Current. 

 Cruises A2-1, A3-3, and A3-4 were made by the 

 ocean station vessels USCGC HUMBOLDT 

 (WHEC 372) and USCGC DUANE (WHEC 

 33) prior to the beginning of the Ice Patrol re- 

 search, but the data were presented in graphical 

 form with the 1966 Ice Patrol data. Cruise A3-3 

 by the USCGC DUANE was accomplished en 

 route Ocean Station BRAVO in February 1966. 

 The data are listed by NODC as Ref. No. 31-792 

 and as table II of this report. The data from 

 cruises A2-1 and A3-4 were collected by the 

 USCGC HUMBOLDT also en route to Ocean 

 Station BRAVO in March 1966. The data are listed 

 by NODC as Ref. No. 31-702 and as table III of 

 this report. All these data are published in the 

 U.S. Coast Guard Oceanographic Report No. 13, 

 "Oceanography of the Grand Banks Region and 

 the Labrador Sea in 1966," Wolford, T. C. (in 

 press).
