Shevenell, Amelia E.; Kennett, James P.; Lea, David W. (2004): Middle Miocene Southern Ocean cooling and Antarctic cryosphere expansion. American Association for the Advancement of Science, Washington, DC, United States, Science, 305 (5691), 1766-1770, georefid:2005-032178

Magnesium/calcium data from Southern Ocean planktonic foraminifera demonstrate that high-latitude ( approximately 55 degrees S) southwest Pacific sea surface temperatures (SSTs) cooled 6 degrees to 7 degrees C during the middle Miocene climate transition (14.2 to 13.8 million years ago). Stepwise surface cooling is paced by eccentricity forcing and precedes Antarctic cryosphere expansion by approximately 60 thousand years, suggesting the involvement of additional feedbacks during this interval of inferred low-atmospheric partial pressure of CO (sub 2) (p (sub CO2) ).
