| **Introduction and         Background**

Paleoceanographers use the distribution of planktic         foraminifers in sediment samples to estimate past oceanographic and paleoclimatic         conditions (see Murray, 1995 for review).  Analysis of climate and         environmental variability on the decadal to millenial scale requires a         taxonomically stable and well-dated core-top calibration data set.          Databases used in global reconstructions of the last glacial maximum (Cline         and Hays, 1976; CLIMAP, 1976; 1981), last interglacial (CLIMAP, 1984),         and middle Pliocene (Dowsett et al., 1999) do not always meet these requirements.          In this report we present planktic foraminifer faunal census data and         AMS 14C data which can be be used in investigations of climate         variability in the Gulf of Mexico region (eg. Poore et al., in review).         More comprehensive interpretation and analysis of these data, aimed at         developing a temporally and taxonomically stable data set will follow         in other publications (see Dowsett et al., 2002). |
