INTRODUCTION 



The data contained in this report represents 

 the beginning of the time-series study by the 

 U. S. Coast Guard of the oceanographic envi- 

 ronment at Ocean Station NOVEMBER 

 (30°00'N, 140°00'W). The location of NOV- 

 EMBER in relation to the other Ocean Stations 

 of the world is shown in Figure 1. The Ocean 

 Station vessels presently make daily Nansen 

 bottle casts to 1500 metei-s on altei-nate 21 day 

 patrols. Serial observations of temperature and 

 salinity are made at all stations. This report 

 contains the data for 76 oceanographic stations 

 at NOVEMBER during July 1966-Febi-uary 

 1967, taken by three U. S. Coast Guard cutters. 

 They were the CGC GRESHAM, 31 July-24 

 August 1966; CGC KLAMATH, 11 Septem- 

 ber-1 October; CGC WACHUSETT, 19 Nov- 

 ember-3 December 1966; and the CGC GRES- 

 HAM, 10-28 February 1967. 



PROCEDURES 



For daily casts the prescribed sample depths 

 are 0, 10, 30, 50, 75, 100, 150, 200, 300, 400, 

 600, 800, 1000, and 1500 meters. For deep casts 

 they are 2000, 2500, 3000, 4000, 4500, and 4600 

 meters (near bottom). A pair of deep-sea re- 

 versing thermometers is fitted to each Nansen 

 bottle, and in addition, on five bottles from 200 

 to 1500 meters, an unprotected thennometer 

 is paired with the two protected ones for the 

 thermometric determination of the sampling 

 depths. Depths which are determined thenn- 

 ometrically are preceded by a "T" in the sta- 

 tion data. Field obsei-vations are transmitted 

 via radio teletype to the Coast Guard Ocean- 

 ographic Unit (CGOU) for real-time quality 

 control and data processing. Procedures used 

 in recording and processing the temperature 

 data essentially follow those outlined in U.S.- 

 N.H.O. Pub. No. 607 (1955) and LaFond 

 (1951). CGOU uses a Digital Equipment Cor- 

 poration PDP-5 computer to process the tem- 

 perature data. 



Salinity samples are drawn from each Nan- 

 sen bottle, and the salinity is detennined 

 aboard ship using inductive salinometers. Du- 

 plicate samples are drawn from the top and 

 bottom bottle at each station and delivered to 

 CGOU for quality control when the vessel re- 

 turns to port 



Processed temperature and salinity were 

 recorded on form NHO/NODC 3167/(1-61), 



Physical and Chemical Data form for ocean- 

 ographic stations and delivered to the National 

 Oceanographic Data Center (NODC). The in- 

 terpolated temperatures and salinities for 

 standard depths, sigma-t, specific volume 

 anomalies (aD), and sound velocities were 

 computed by NODC and listings provided for 

 the preparation of Tables I-IV. 



On the first Coast Guard Oceanographic 

 patrol at NOVEMBER during 31 July-24 

 August 1966, the CGC GRESHAM successfully 

 occupied 25 stations. The U.S. Naval Ocean- 

 ographic Office and the Scripps Institute of 

 Oceanography had made previous investiga- 

 tions.' Twenty-three stations had maximum 

 useful depths between 1350 and 1800 meters. 

 One station had a maximum sample depth of 

 1009 meters due to a malfunction of the bottom 

 bottle. One deep cast was made to a depth of 

 3696 meters in a water depth of 4389 meters. 

 Salinity samples were not taken on station 16 

 and 21-25 due to a breakdown of the salino- 

 meter and a shortage of sample bottles. The 

 distribution of the stations about the center of 

 NOVEMBER is shown in Figure 2. The data 

 is carried by NODC as Ref. No. 31-749GH and 

 listed in Table I of this report. 



On the 11 September-1 October 1966 patrol 

 of the CGC KLAMATH, twenty-one ocean- 

 ographic stations were occupied. Nineteen sta- 

 tions had maximum useful depths between 

 1350 and 1700 meters. One station had a maxi- 

 mum depth of 1015 meters due again to a mal- 

 function of the 1500 meter bottle. One deep 

 cast was made to a depth of 4422 meters in an 

 estimated depth of water of 4500 meters. The 

 distribution of the stations about the center of 

 November is shown in Figure 3. The data is 

 listed by NODC as Ref. No. 31-768KL and as 

 Table II of this report. 



The CGC WACHUSETT occupied 12 ocean- 

 ographic stations on the 19 November-3 De- 

 cember 1966 patrol. Eleven stations were rou- 

 tine shallow casts with maximum useful depth 

 between 1350 and 1800 meters. One deep-cast 

 was accomplished to a depth of 4399 meters in 

 a water depth of 4481 meters. The distribution
