Carbon associated with CaCO3 was calculated as the difference between two independent analyses of aliquots from the same interval: Total carbon (=CaCO3 and POC) from the bulk sediment and organic carbon measured after pretreatment with hydrochloric acid to remove carbonates. The method is described in Lyle et al. (2000).
