Research Abstract |
We developed a method to identify foraminiferal metabolic activities in situ. Also, we found a novel tool to estimate the degree of denitrification in foraminiferal cells by comparing nitrogen isotopic compositions of amino acids in foraminiferal cell and in organic matter of foraminiferal test. This will be useful proxy to estimate foraminiferal respiration from shallow water to deep-sea.
