Abstract

Brachiopods have been employed for environmental and climatic reconstructions in the near and geological past. Traditionally, one datapoint is obtained per shell, providing time-averaged bulk signals. However, brachiopods also have the potential to provide time-resolved information on (sub)annual timescales, but this has been understudied due to difficulties in accounting for brachiopod shell growth. We investigated the distribution of δ¹⁸O, δ¹³C and Element/Ca along growth profiles of three Recent terebratulides from temperate and polar latitudes. We employed a novel approach using the Brody–Bertalanffy equation to transform shell distances into ages, permitting the study of periodicity in the measured signatures. We show that, superimposed on ontogenetic trends, faster-growing temperate species record annual and intrannual changes at collection sites, whereas slower-growing Antarctic species are also controlled by endogenous cycles. δ¹⁸O profiles reflect annual and intrannual variations in midlatitudes and interannual variations at high latitudes. δ¹³C and Element/Ca are additionally influenced by vital effects.
