Sedimentary census counts at IODP Site 383-U1542 during Marine Isotope Stage 12-10

This dataset presents sedimentary census counts at International Ocean Discovery Program Site U1542 (52°42.292ʹS, 75°35.769ʹW; 1,101 m water depth) during Marine Isotope Stage 12-10 and includes the abundance of the planktic foraminifer Neoglobaquadrina pachyderma, the amount of foraminiferal shell fragmentation and the presence of siliciclastic grains. The abundance of N. pachyderma was calculated relative to the total number of planktic foraminifera in the sample and converted to summer sea surface temperature based on the calibration of Govin et al. (2009). The amount of foraminiferal shell fragmentation was calculated relative to the total number of foraminifera in the sample. The abundance of IRD was determined relative to the sum of foraminiferal specimens and siliciclastic grains in the sample in percent. In samples with >90% siliciclastic grains, and significantly less than 300 intact planktic foraminifera, the N. pachyderma abundance and the foraminiferal shell fragmentation was not determined. Replicate counts of the same sample aliquot were completed to determine uncertainties of the census counts.
