DATA: Oxygen isotope composition of final chamber of planktic foraminifera provides evidence for vertical migration and depth integrated growth H. Pracht, B. Metcalfe, and F. Peeters

Short summary
In palaeoceanography the shells of single-celled foraminifera are routinely used as proxies to reconstruct the temperature, salinity and circulation of the ocean in the past. Traditionally a number of specimens were pooled for a single stable isotope measurement; however, technical advances now mean that a single shell or chamber of a shell can be measured individually. Three different hypotheses regarding foraminiferal biology and ecology were tested using this approach.
