Expedition 400 methods

The procedures and tools employed in coring operations and in the various shipboard laboratories of the R/V JOIDES Resolution are documented here for International Ocean Discovery Program (IODP) Expedition 400. This information applies only to shipboard work described in the Expedition reports section of the Expedition 400 Proceedings of the International Ocean Discovery Program volume. Methods for shore-based analyses of Expedition 400 samples and data will be described in separate individual publications. This introductory chapter describes the procedures and equipment used for drilling, coring, core handling, and sample registration; the computation of depth for samples and measurements; and the sequence of shipboard analyses. Subsequent sections describe laboratory procedures and instruments in more detail.

Unless otherwise noted, all depths in this volume refer to the core depth below seafloor, Method A (CSF-A), scale (in meters), which is equivalent to the meters below seafloor (mbsf) scale.
