Abstract:	The Bølling-Allerød deglacial event is marked by high diatom productivity and opal deposition throughout the subarctic Pacific. To investigate the cause of this event, we quantified several productivity-related sedimentary parameters that reflect the near-surface biogeochemistry from the Integrated Ocean Drilling Program (IODP) Site 323-U1340 in the Bering Sea. Radiocarbon data, originally published in Schlung et al. (2013, doi:10.1029/2012PA002365), were re-calibrated using Calib 8.2 (Stuiver & Reimer, 1993; doi:10.1017/S0033822200013904).
