Over the past decade deep-sea (cold-water) corals have emerged as a new archive of ocean dynamics and climate change. Numerous species can be precisely dated, provide rapidly growing aragonite skeletons to investigate novel geochemical tracers and occur with high spatial and temporal coverage throughout the world oceans. Since the late nineties much progress on dating tools, tracer developments and bio-mineralization have been made, indicating climate and oceanic changes from decades to hundreds of thousands of years. Consequently, we invite here to present records of present and past ocean dynamics and climate change including ocean acidification as derived from deep-sea corals and we greatly welcome furthermore studies on cold-water coral bio-mineralization and reef development.
