The following tables contain the corrected temperature and salinity 
data for the 127 oceanographic stations occupied by the U.SS. 
Hannibal between March 9, 1933, and May 24, 1933, in the Pacific 
Ocean. These are stations H-17 to H—102, located in the Gulf of 
Panama and occupied between March 9 and March 24, and stations 
H-105 to H—-145, situated off the Pacific coast of Costa Rica and 
Panama and occupied between May 16 and May 24. . The prefix 
‘‘H-”’ has been used to denote the collecting vessel, namely, the 
U.S.S. Hannibal. H-103 was a test station run in shallow water 
and the results are not included. The serial number H-104 was 
accidentally omitted. 
The tables contain the temperature observations, which have been 
carefully corrected and checked, and the chlorinity and salinity 
determinations, which were made at the Scripps Institution of Ocean- 
ography. All of this material has been checked and all doubtful 
observations thrown out. For those stations at which the collections 
were not obtained at the standard depths, tables have been prepared 
that give the interpolated temperature and salinity values at stand- 
ard depths. This has been done to facilitate comparisons between 
stations and to simplify the dynamic computations. For the stations 
H-105 to H-145, for which the preliminary dynamic computations 
have been made, the o;, and V,, ;, , values are included in these tables. 
The temperature observations have been corrected in the following 
ways. For those thermometers for which the V, value was known, 
the temperature readings were corrected from tables compiled from 
data based on Schumacher’s formula. The V, is the volume of 
mercury in the thermometer when reversed at 0° C. expressed in 
degrees. For those thermometers for which the V, value was not 
given the corrections were made from tables compiled from graphs 
for each thermometer based upon the calibration data supplied by 
the United States Bureau of Standards. After these corrections had 
been applied it was found that certain of the thermometers showed 
small constant errors. These were determined by comparison with 
trustworthy thermometers and the necessary corrections applied. 
The probable error of the corrected temperature observations was
