Such are likely victims of mass mortality result- 

 ing from an invasion of hydrogen sulfide water or 

 red water situations which, while reported in 

 Walvis Bay, South Africa (Brongersma-Sanders, 

 1957), do not seem characteristic of the present 

 coastal waters off the Californias. On the other 

 hand, the occurrence of separate scales is likely 

 the incidental result of serious if not fatal trophic 



interactions. Previous investigation has indicated 

 that, with few exceptions, fish scales are deposited 

 in Santa Barbara Basin as individual events 

 (Soutar, 1967). 



Interstitial-water measurements (Sholkovitz, 

 1973) indicate an increase of dissolved phosphate 

 within the anaerobic sediment from 20 m moles 

 POi" near the surface to levels in excess of 100
