 The first part of the cruise, station numbers 1 to 80 was made aboard the 

 HUGH M. SMITH in April and May 1959 on its last cruise for the Honolulu

 part of the cruise was made along the west coast of the United States aboarr 

 the SCOFIELD a California State Fish and Game vessel. 400 was added to the 

 station numbers of SCOFIELD so in the table SCOFIELD stations are numbered -109
