Abstract

Cells of the giant diatom Ethmodiscus Castr. gathered from the upper 15 m were examined for O2 evolution, nitrate reductase activity (NRA), C and N composition, internal NO concentrations, , and 15NO, 15NH , and 32Si uptake in a series of cruises in the central N. Pacific gyre. The δ15N (2.56–5.09 ‰...
