New study on coral growth in times of climate change

35 million years ago, an asteroid struck the east coast of North America. Ejected material from the impact site was distributed over an area of at least 7 million square kilometres (Tektite field). In drilling samples taken from the sea floor 400 kilometres from the point of impact (ODP 1073), researchers have now found clear traces of the impact and dated them for the first time using the uranium-thorium-helium technique.

Currently, organic material in the ocean is mainly degraded with oxygen (left). Together with a warming of the ocean this leads to deoxygenation. In a future, warmer ocean (right), more organic material is respirated by denitrification with nitrate. The associated oxygen saving would even exceed the oxygen loss due to warming.
