Survey data collected from Core E53-10, located on the edge of the South Tasman rise
Most globally linked climatic records dealing with continuous longterm change are derived from the ocean sea-floors where sedimentation of microplankton is accumulated on a time scale of several centimetres per 1000 years. Variations in microfossil records over time are used as proxies for changes i...
