Abstract

In 2009, Integrated Ocean Drilling Program (IODP) Expedition 323 drilled at seven sites in the Bering Sea. The primary objective of this expedition was to investigate high-resolution paleoceanographic history in the Bering Sea during the past 5 m.y. Expedition 323 was a part of IODP Proposal 477, which included areas of both the Bering and Okhotsk Seas. As part of the proposal, we conducted marine geophysical and geological surveys in the Bering Sea using the R/V Hakuhou-maru. During that cruise, we collected swath bathymetry, subbottom profiles, seismic reflection data, and sediment cores, all of which form the primary site survey data set on which Expedition 323 drill sites are located. This paper presents site survey data collected during the Hakuhou-maru survey with available survey data from other cruises.
