MARC recordEarly Pliocene deglaciation of the Antarctic ice sheet and Late Pliocene onset of bipolar glaciation / D.M. Harwood, P.-N. Webb.
| Title: | Early Pliocene deglaciation of the Antarctic ice sheet and Late Pliocene onset of bipolar glaciation / D.M. Harwood, P.-N. Webb. |
| Author(s): | Harwood, D. M. Webb, P. -N. |
| Date: | 1990. |
| In: | Eos : transactions, American Geophysical Union. (1990.), Vol. 71(17) (1990) |
| Abstract: | Oxygen isotope shift in deep-sea sediments at 2.4 Ma used to infer onset of northern-hemisphere glaciation also marks significant ice-volume increase in Antarctica. Shift has been attributed to ice growth in northern hemisphere, but geological evidence from Antarctica suggests considerable ice-volume variation before and after Middle Miocene, including major deglaciation during Early Pliocene. Climatic implications discussed. |
| Notes: | Eos : transactions, American Geophysical Union. Vol. 71(17) :538-539 (1990). Abstract for 1990 MSA/AGU Spring Meeting, 29 May-1 June, Baltimore, MD. |
