Calcium isotope ratios of marine carbonates and sea water
Listed in PANGAEA and DataCite — shown once because both records carry DOI 10.1594/pangaea.707903
Significant variations in the isotopic composition of marine calcium have occurred over the last 80 million years.
Description
These variations reflect deviations in the balance between inputs of calcium to the ocean from weathering and outputs due to carbonate sedimentation, processes that are important in controlling the concentration of carbon dioxide in the atmosphere and, hence, global climate. The calcium isotopic ratio of paleo-seawater is an indicator of past changes in atmospheric carbon dioxide when coupled with determinations of paleo-pH.
