Abstract
PRIMARY oscillations, corresponding to long-period changes in temperature in the upper layer of the sea, have been reported in long cores from Equatorial and North Atlantic, the Caribbean and Mediterranean Seas1–3. These changes, apparently the equivalent of glacial and interglacial periods, have been followed by: oxygen-18/oxygen-16 measurements on selected species of Foraminifera which deposit their tests in the upper layer of the sea; determining the proportions of planktonic Foraminifera characteristic of warm, temperate and cool waters; carbonate analyses and grain size determinations.
