Kelly, D. Clay (2002): Response of Antarctic (ODP Site 690) planktonic Foraminifera to the Paleocene-Eocene thermal maximum; faunal evidence for ocean/climate change. American Geophysical Union, Washington, DC, United States, Paleoceanography, 17 (4), georefid:2003-069544

Abstract:
High-resolution study of Antarctic planktonic foraminiferal assemblages (Ocean Drilling Program Site 690, Weddell Sea) shows that these microplankton underwent a stepwise series of changes during the Paleocene-Eocene thermal maximum (PETM). Initiation of this response coincides with the onset of the carbon isotope excursion (CIE) but precedes the benthic foraminiferal mass extinction. The "top-to-bottom" succession in the biotic response indicates that the surface ocean/atmosphere was affected before the deep sea. The earliest stage of the faunal response entailed a conspicuous turnover within the shallow-dwelling genus Acarinina and a succession of stratigraphic first appearances. (modified journ. abst.)
