Preface

Integrated Ocean Drilling Program (IODP) Expedition 306 is based on two separate proposals entitled (A) “Ice sheet–ocean atmosphere interactions on millennial timescales during the late Neogene–Quaternary using a paleointensity-assisted chronology (PAC) for the North Atlantic” and (B) “Installation of a circulation obviation retrofit kit (CORK) near Hole 642E to document and monitor bottom water temperature variations through time.” Since both parts are independent of each other, the introductory sections of the Expedition 306 report (introduction, background, geological setting, and objectives) have been divided into Part A and Part B. Sites U1312, U1313, and U1314 are related to the North Atlantic paleoceanography study (Part A), whereas Site U1315 and the revisited Ocean Drilling Program (ODP) Hole 642E are related to the CORK program (Part B).
