As expected from previous work in the tropics, all dominant tropical species occur in greatest abundance within the photic zone. Many species occur in greatest abundances in the seasonal thermocline in association with the maximum chlorophyll concentration, while a few algal symbiont‐bearing species occur in greatest abundance in the mixed layer. The δ<jats:sup>18</jats:sup>O measurements of planktonic foraminifera shells from core top sediment samples confirm the vertical stratification within the photic zone that is suggested by the relationship between hydrography and abundances found in the plankton tows and found in the statistical study by Ravelo et al. [1990]. Comparison between the measured δ<jats:sup>18</jats:sup>O values of planktonic foraminifera with the predicted δ<jats:sup>18</jats:sup>O profiles of the overlying water column at three core locations indicate that species abundances in the sediment record the seasonally integrated conditions of the photic zone and suggests that the abundance of a species in the sediment depends on whether the preferred ecological conditions of that species may be found within the photic zone of the overlying water column sometime during the year. Species which calcify below the photic zone have only trace relative abundances. Finally, it appears that the total range of δ<jats:sup>18</jats:sup>O values of the dominant species approximates the predicted annual δ<jats:sup>18</jats:sup>O of calcite range in the upper 80 m of the water column.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1583387451214276480","@type":"Researcher","foaf:name":[{"@value":"A.
