Summary: A newly recognized carbonate preservation event (CPE) dated between 11 and 12 Ma was identified in Hole U1361A during Integrated Ocean Drilling Program Expedition 318 in the Southern Ocean based on CaCO3 content and the preservation of foraminiferal tests. High carbonate content occurs within the interval between 311.60 and 349.99 meters below seafloor, whereas CaCO3 content was typically near 1 wt% for the rest of the core. In addition, benthic and planktonic foraminifers were relatively abundant. However, stable isotope measurements carried out within this interval contained unrealistic values, which we ascribe to postdepositional diagenetic alteration by the release of methane. This prohibited quantification of temperature, ice volume, and salinity. The CPE identified at Hole U1361A was also observed at Ocean Drilling Program Site 689, which is correlated to the Mi5 glaciation. We hypothesize that this Southern Ocean CPE and the diagenetic alteration of foraminifers were due to both the Mi5 glaciation and reorganization of ocean circulation.
