Coral reef ecosystems and anthropogenic climate change
Another important study reported on the EPOCA blog Coral reef ecosystems are among the most biologically diverse ecosystems on the planet. In addition to their value in terms of biodiversity, coral reefs provide food and resources for over 500 million people. Despite their importance, coral reefs are declining at a

Sr/Ca sensitivity to aragonite saturation state in cultured subsamples from a single colony of coral: mechanism of biomineralization during ocean acidification
Posted on EPOCA: 12 Dec 2012 Using a new and rapid NanoSIMS-based method, we quantified the sensitivity of skeletal Sr/Ca in coral to the aragonite saturation state of seawater (ΩSW). Skeletal Sr/Ca is a common proxy for temperature while ΩSW is a parameter that varied in the past ocean and is
