Glass sponges – a new paleoclimate archive
Jochum, Klaus Peter; Andreae, Meinrat O.
SummaryScientists of the Max Planck Institute for Chemistry in Mainz have investigated up to 2.70 m long giant spicules of the deep-sea glass sponge Monorhaphis chuni by new microanalytical techniques. They showed that the lifespan of these biogenic silica structures can be up to 13,000 years. Giant spicules therefore offer a unique opportunity to record changes of past oceanic and climatic conditions.
