Environmental and biological controls on Na∕Ca ratios in scleractinian cold-water corals

Here we present a comprehensive attempt to correlate aragonitic Na/Ca ratios from Desmophyllum pertusum (formerly known as Lophelia pertusa), Madrepora oculata and a caryophylliid cold-water coral (CWC) species with different seawater parameters such as temperature, salinity and pH. Living CWC speci...

Zusammenfassung:	Here we present a comprehensive attempt to correlate aragonitic Na/Ca ratios from Desmophyllum pertusum (formerly known as Lophelia pertusa), Madrepora oculata and a caryophylliid cold-water coral (CWC) species with different seawater parameters such as temperature, salinity and pH. Living CWC specimens were collected from 16 different locations and analyzed for their Na/Ca ratios using solution-based inductively coupled plasma-optical emission spectrometry (ICP-OES) measurements.
