Fig. 80. Showing the vertical distribution of 



Metridia gerlachei, Giesbr. 

 down to 500 m. on lines of stations in the South 

 Georgia December-January 1926-7 survey. 



The scale represents the numbers per 50 m. vertical haul 

 taken by closing (N 70 V) nets in a series of hauls : 500-250, 

 250-100, 100-50 and 50-0 m. (as far as depth will allow). 

 For distribution at greater depths see Appendix II. For 

 accompanying hydrological conditions see Figs. 7 and 8.
