Introduction The data sets in this study are from two cores in the southeast Bering Sea, HLY02-02-51JPC (54.5532N, 191.3331E, 1467 m water depth) and HLY02-02-57JPC (54.5300N, 192.4532E, 700 m water depth) and include delta-oxygen-18 and delta-carbon-13 measurements on Neogloboquadrina pachyderma (sinistral) (for 51JPC, 2010pa001993-ts01; for 57JPC, 2010pa001993-ts02) and Uvigerina peregrina (for 51JPC, 2010pa001993-ts03; for 57JPC, 2010pa001993-ts04), the absolute abundance of benthic foraminifera (for 51JPC, 2010pa001993-ts05; for 57JPC, 2010pa001993-ts06), the percent total organic carbon and the abundance and delta-carbon-13 of archaeol and DAGE-C30 (for 51JPC, 2010pa001993-ts07; for 57JPC, 2010pa001993-ts08), and the delta-carbon-13 of tetraether-derived biphytanes (for 51JPC, 2010pa001993-ts09; for 57JPC, 2010pa001993-ts10). Two auxiliary figures are included, 2010pa001993-fs01 and 2010pa001993-fs02. Finally, there is a brief text file 2010pa001993-txts01 describing the methods and results of Mg/Ca analysis in 51JPC. 1. 2010pa001993-ts01.txt Stable isotopes measured on Neogloboquadrina pachyderma (sinistral) in HLY02-02-51JPC. 1.1 Column 'depth', depth in core (cm) 1.2 Column 'depthc', composite depth in core, with core gaps removed (cm) 1.3 Column 'age', interpolated calibrated calendar age (ky BP) 1.4 Column 'd13C', delta-carbon-13 (permil VPDB) 1.5 Column 'd18O', delta-oxygen-18 (permil VPDB) 2. 2010pa001993-ts02.txt Stable isotopes measured on Neogloboquadrina pachyderma (sinistral) in HLY02-02-57JPC. 2.1 Column 'depth', depth in core (cm) 2.2 Column 'depthc', composite depth in core, with core gaps removed (cm) 2.3 Column 'age', interpolated calibrated calendar age (ky BP) 2.4 Column 'd13C', delta-carbon-13 (permil VPDB) 2.5 Column 'd18O', delta-oxygen-18 (permil VPDB) 3. 2010pa001993-ts03.txt Stable isotopes measured on Uvigerina peregrina in HLY02-02-51JPC. 3.1 Column 'depth', depth in core (cm) 3.2 Column 'depthc', composite depth in core, with core gaps removed (cm) 3.3 Column 'age', interpolated calibrated calendar age (ky BP) 3.4 Column 'd13C', delta-carbon-13 (permil VPDB) 3.5 Column 'd18O', delta-oxygen-18 (permil VPDB) 4. 2010pa001993-ts04.txt Stable isotopes measured on Uvigerina peregrina in HLY02-02-57JPC. 4.1 Column 'depth', depth in core (cm) 4.2 Column 'depthc', composite depth in core, with core gaps removed (cm) 4.3 Column 'age', interpolated calibrated calendar age (ky BP) 4.4 Column 'd13C', delta-carbon-13 (permil VPDB) 4.5 Column 'd18O', delta-oxygen-18 (permil VPDB) 5. 2010pa001993-ts05.txt Absolute abundance of benthic foraminifera in HLY02-02-51JPC. 5.1.
