Objectives
2 To quantify the relative importance of inorganic nitrogen (autotrophy) vs. organic nitrogen (heterotrophy) in skeletogenesis. 3 To evaluate how varied modes of coral nutrition among three major genera of corals affect the source of nitrogen incorporated in the organic matrix. 4 To identify the spatial distribution patters of carbon and nitrogen within the coral skeletal anatomy (septae, columellae, thecae) , and determine the relative calcification rate within each.
