Abstract

Alkenone paleothermometry has been used for generating late Quaternary records of sea surface temperature from deep-sea core sediments. This paper summarizes its principles, applications, problems and future. A critical problem comes from culture experiments of <i>Emiliania huxleyi</i> and <i>Gephyrocapsa oceanica</i>. The results indicate large variations in the U<sub>37</sub><sup>K'</sup>-temperature relationship among different species or strains. Even single strains show variations in U<sub>37</sub><sup>K'</sup> in different growth phases and culture conditions. These suggest that some physiological or environmental factor, in addition to temperature, affects U<sub>37</sub><sup>K'</sup>. To find this factor is strongly sought for the future application of alkenone paleothermometry.
