Microscopic Sea Shells – Part 2

Posted by Laura Ashby on September 2nd, 2007

On Foraminifera and Radiolaria (which are also microscopic sea shells):

‘The importance of both stems from the fact that radiolaria and planktonic foraminifera live at or near the ocean surface and their shells incorporate a record of surface-water conditions as they grow. But it is the calcareous sediments, formed by the rain of dead planktonic foraminifera through the abyss, that have traditionally formed the backbone of climatic and oceanographic research.’

Richard Corfield, The Silent Landscape: In the Wake of HMS Challenger 1872-1876, London: John Murray, 2004, p.135
