13C) of carbonates has been widely used to implicate paleoclimate and paleoecology.
However, results from field observations and laboratory experiments have shown that the δ
13C difference between calcite and solution can vary up to 3‰ even under a similar set of solution composition and temperature, raising uncertainties on implications for paleoclimate and paleoecology.
Researchers from the Institute of Geochemistry of the Chinese Academy of Sciences (IGCAS) reveal that the different thicknesses of the stagnant liquid layer between solid and well mixed bulk solution (i.e., diffusion boundary layer, DBL) may cause the large δ
13C difference between calcite and solution in nature.

The ancient burrowers of the seafloor have been getting a bum rap for years.
These prehistoric dirt churners a wide assortment of worms, trilobites, and other animals that lived in Earth s oceans hundreds of millions of years ago are thought to have played a key role in creating the conditions needed for marine life to flourish. Their activities altered the chemical makeup of the sea itself and the amount of oxygen in the oceans, in a process called bioturbation.
