Species of Globorotalia are among the most dissolution-resistant planktonic foraminifers in sediments of the inner wall of the Middle America Trench; parts of their Phylogenetic history have been recognized in sediments of Leg 107 (Glacon and Bourgois, 1985). These species can be integrated into the biostratigraphic scheme on the basis of calcareous and siliceous nannoplankton and calibrated on the basis of paleomagnetism (Keller, 1980, 1981; Keller et al., 1982; Barron and Keller, 1982). Data compiled for this data report extend to the southern area of occurrence of Globorotalia species. About 250 sediment samples were collected on board JOIDES Resolution and examined as follows: 20-cm**3 samples were dried for 8 hr at 60°C, weighed, and then washed through sieves of 0.5, 0.2, 0.125, and 0.063 mm mesh size. The residues were dried and reweighed. The abundance of planktonic foraminifers counted is reported as numbers of specimens per weight of the original sample.Taxonomic Coverages
