Abstract

Subtraction from the new data, of a quadratic surface fitted to the taxonomic diversity data of recent planktonic foraminifera yields a residual surface closely related to ocean current systems. This technique could be applied to fossil materials to develop knowledge of ocean circulation patterns during glacial and interglacial climatic episodes.
