Summary: A high-resolution benthic carbon and oxygen stable isotope record for marine isotope Stages (MIS) 1.6 at Site U1344 in the Bering Sea is presented here. In addition, a low-resolution record is provided for the remaining part of the stratigraphic section recovered at the site, which spans the past 1.9 My. Sediment samples were analyzed from Holes U1344A, U1344D, and U1344E, which were cored proximal to the Beringian continental slope (59°03'N, 179°12'W; 3184 m water depth) during Integrated Ocean Drilling Program Expedition 323. Primarily, two benthic foraminiferal species, Uvigerina senticosa and Elphidium batialis (both shallow infauna) were used for isotopic measurements. In their absence, Valvulineria sadonica, Globobulimina pacifica, and Nonionella labradorica were used. An offset of 0.9 ppm in the oxygen isotopic composition between U. senticosa and E. batialis was observed. The average sedimentation rate for the last two glacial.interglacial cycles (upper 64 m core composite depth below seafloor [CCSF-A]) was ∼40 cm/ky regardless of its water depth (>3000 m).
