Data-Base of Antarctic Pre-Pleistocene Sediment Cores

摘要

A listing of high southern latitude (>30 deg S) pre-Pleistocene sediment cores is given for samples obtained by the coring and drilling programs of the Lamont-Doherty Geological Observatory, the Antarctic Program of the Florida State University, the French Museum National d'Histoire Naturelle, and the Deep Sea Drilling Program. Information on geologic age, core length, lithology, bathymetry, and geographic location are given for each sediment sample. Ages of cores are given whenever possible to the nearest sub-epoch (middle Miocene, etc), together with (when known) the fossils used to determine the age, and the source of the age determination. Many core ages are from previously unpublished sources. The listing provides information on approximately 500 different cores. A computer-searchable version of the data base may be obtained by writing to the senior author. A brief analysis of latitudinal and bathymetric patterns of sedimentation is also given for the Paleogene, Miocene, and Pliocene of the Southern Ocean.
