Integrated Ocean Drilling Program (IODP) Expedition 306 is the second cruise of the North Atlantic Climate study that aims to generate a late Neogene–Quaternary chronostratigraphic template for North Atlantic climate proxies to allow their export and correlation at a sub-Milankovitch scale, by using a paleointensity-assisted chronology (PAC). Expedition 306 also will include installation of a CORK (Circulation Obviation Retrofit Kit) at Ocean Drilling Program (ODP) Site 642 (Vøring Plateau, Norwegian margin) to investigate the feasibility of reconstructing bottom water temperature histories at the decade to centennial timescale by making high-precision temperature-depth measurements. The objectives at Site 642 are summarized in "CORK Installation at ODP Site 642" in the Expeditions 303/306 Scientific Prospectus. This addendum also aims to provide guidance to the science party for completing sample requests and initiating scientific collaboration discussions. Please refer to the Scientific Prospectus for detailed information regarding scientific objectives, original sites, and other information.
The ultimate objective is to generate a chronostratigraphic template for North Atlantic climate proxies to allow their export and correlation at a sub-Milankovitch scale.
