As part of our ongoing evaluation of the shell weight proxy, measurements were carried out on plankton species from South Atlantic cores. The results portray a complex picture. Whereas ideally these weights should be influenced only by surface water carbonate ion concentration (growth weight) and deep water pressure‐normalized carbonate ion concentration (extent of weight loss due to dissolution), it appears that other environmental factors may influence growth weight and that variable pore water ‐ bottom water offsets may complicate the extent of dissolution.
