Nitrogen sources for phytoplankton in the eastern Indian Ocean determined from δ15N of chlorophyll a and divinylchlorophyll a.

Nitrogen and carbon isotopic compositions of bulk SPM (gray squares), chlorophyll a (green circles), chlorophyll b (red circles), divinylchlorophyll a (blue triangles), and divinylchlorophyll b (orange triangles) at the subsurface chlorophyll maximum along 88°E transect in the eastern Indian Ocean. The error bars represent the analytical precision of the nano-EA/IRMS.
