From the Arctic to the Antarctic: the major, minor, and trace elemental composition of echinoderm skeletons
Abstract Biogenic carbonate production in benthic marine ecosystems is dominated by representatives of the Echinodermata. Carbon and other major, minor, and trace elements are exported to the seabed where they accumulate or dissolve. Preserved carbonates (Mg-calcite) have applications in oceanograph...

Abstract Biogenic carbonate production in benthic marine ecosystems is dominated by representatives of the Echinodermata. Carbon and other major, minor, and trace elements are exported to the seabed where they accumulate or dissolve. Preserved carbonates (Mg-calcite) have applications in oceanography and geochemistry and are used to reconstruct various parameters of ancient seawater, such as temperature (from Mg/Ca, Sr/Ca), seawater Mg/Ca (from Mg/Ca), and pH (from B/Ca). In general, the benthos is widely ignored for its role in the global carbon cycle despite the importance of echinoderms as a carbon sink (∼0.1–0.2 Pg C/yr). Echinoderms produce their skeletons from Mg-calcite, which is more soluble than pure calcite and, therefore, more vulnerable to ocean acidification (OA). Minor and trace elements can also destabilize the calcite lattice, increasing the mineral's solubility. Little is known about the concentration of such elements in echinoderm tests.
