Here we present changes in abundances and δ13C and δ18O composition of five size fractions of bulk sediments from ODP Site 1209 in Shatsky Rise, north-central Pacific, deposited BETWEEN 58-50 Ma. The dataset includes four tables. The bulk sediments were rinsed and segregated into five size fractions: 250 μm. The difference in mass of sediments before and after size-fraction separation is reported in the first sheet. The second sheet documents temporal changes in relative weights of the various size fractions: namely fine fraction (FF), intermediate fraction (IF), coarse fraction (CF) and the three sub-fractions of CF. The δ13C and δ18O composition of bulk sediments and size fractions are reported in the third and fourth sheets, respectively
