Abstract--Offsets from isotopic equilibrium in biogenic carbonates have complicated paleoclimate recon-
structions for decades. A new archive of climate, deep-sea corals, is used to evaluate the calcification
processes, independent of photosynthesis, that contribute to these offsets. Carbon and oxygen stable isotope
data from six modern deep-sea corals show strong linear trends between 13
