Early Eocene to early Miocene magnetostratigraphic framework for IODP Expedition 371 (Tasman Frontier Subduction Initiation and Paleogene Climate)
Week 3 began with the final 245 nmi of the 286 nmi transit to Site U1507 (proposed Site NCTN8A). We arrived at 2200 h on 6 August. After lowering the thrusters and switching to dynamic positioning (DP) mode, the rig floor was cleared for operations, beginning Hole U1507A at 2225 h. The rig crew assembled an advanced piston corer (APC)/extended core barrel (XCB) bottom-hole assembly (BHA) by 0130 h on 7 August, picked up drill pipe and the top drive, and deployed the bit just above the seafloor. A wiper “pig” was pumped through the drill string to clean out potential debris. The nonmagnetic APC core barrels were dressed with core liners in preparation to spudding Hole U1507A at 1040 h.
期刊介绍:
Newsletters on Stratigraphy is an international, peer-reviewed journal with a focus on stratigraphic issues that are relevant for a broad geoscientific community. Papers published in Newsletters on Stratigraphy use (and ideally integrate) stratigraphic methodologies from a wide field of disciplines, including (but not limited to) biostratigraphy, chronostratigraphy, chemostratigraphy, and magnetostratigraphy.
The results have implications for paleogeographic reconstructions, paleoceanography, paleoclimate, biotic evolution, basin development, or regional and supraregional correlation.
Papers published in Newsletters on Stratigraphy comprise original research articles, background information on ongoing work of e.g., the International Stratigraphic Commission (ICS) and the International Subcommission on Stratigraphic Classification (ISSC), and review articles. There are no page charges for the publication of regular papers.
