HYDROGRAPHIC CORRELATIONS 



The hydrographic data for stations adjacent to the place of capture and at depths corresponding to 

 the probable depth of capture, are summarized in Table 8. Selected mean values used for plotting 

 are given in Table 9. The writer is deeply interested in the distribution of bathypelagic marine 

 organisms in relation to water types and has suggested the use of temperature-salinity charts for the 



Table 9. Selected or interpolated values of temperature and salinity at the most probable mean 

 depth of capture, derived from Table 8 and used in plotting the distribution in relation to water 



types {Figs. 2, 3 and 4)
