A turbulent hidden history. (IMAGE)
Caption
The sediment core was previously described as being made up of “homogeneous hemipelagic mud” (fine-grained mud with sediment from the land and ocean). To the naked eye, on X-ray and CT images (a), there do not appear to be any major differences between layers. However, by using radiocarbon dating (b), the team found multiple layers of deposition from geophysical events, revealing a more complex history.
