Abstract:
Down water column traverses of core top weights for three planktonic species confirm Lohmann's (1995) relationship between foraminifera shell weight loss and bottom water carbonate ion content. However, they also suggest that the initial shell thickness varies with growth habitat and that the offset between bottom water and pore water carbonate ion concentration varies even on small space scales.
