(Table 2). The preformed nutrient concentra- 

 tions in the Warm Deep Water and Eastern 

 Weddell Sea Bottom Water are almost identical 

 and significantly lower than that of Antarctic 

 Surface Water. Because of the similarity in 

 preformed values, Warm Deep Water and 



Eastern Weddell Sea Bottom Water can only be 

 separated by temperature, salinity, and oxygen 

 characteristics. The 1970 preformed nutrient 

 concentrations correspond closely with the 1968 

 and 1969 values found by Hufford and Sea- 

 brooke (1970).
