Hole 1090B is located in the central part of the Subantarctic Zone on the southern flank of the Agulhas Ridge (42 degrees 54'S, 8 degrees 53'E). Hole 1090B was drilled to 397.5 meters below seafloor (mbsf), and Holocene to middle Eocene sediments were recovered. Core recovery of the Eocene to lower Oligocene interval was generally good, even though sediments were recovered by the extended core barrel (XCB) system. Because the paleomagnetic signal and nannofossil assemblages are well documented in this interval, Hole 1090B may represent a reference record to improve knowledge of the Eocene-Oligocene transition. We analyzed the calcareous nannofossil assemblages of the middle Eocene to lower Oligocene interval, focusing especially on the Eocene-Oligocene transition, with quantitative investigations of nannofossil assemblages.
