Table T1. Distribution of Eocene to Oligocene calcareous nannofossils, Hole 177-1090B

Hole 1090B is located in the central part of the Subantarctic Zone on the southern flank of the Agulhas Ridge (42°54'S, 8°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 (Shipboard Scientific Party, 1999). 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 (Shipboard Scientific Party, 1999, doi:10.2973/odp.proc.ir.177.105.1999).
