Abstract

The Pacific Equatorial Age Transect (PEAT) program, which includes Integrated Ocean Drilling Program (IODP) Expeditions 320 and 321, was the first scientific program following the complete refit of the R/V JOIDES Resolution. During this process, scientific facilities on the ship were replaced with a completely new structure and all major drilling and ship systems were completely refurbished. All laboratory equipment used on these first two expeditions was new, refurbished, upgraded, or replaced. This was also the first scientific use of the new software controlling the instruments and new database system.

Information assembled in this chapter will help the reader understand the basis for our shipboard observations and preliminary conclusions. It will also enable the interested investigator to identify data and select samples for further analysis. Information presented here concerns only shipboard operations and analyses described in the site chapters. Methods used by various investigators for shore-based analyses of Expedition 320/321 data will be described in individual publications in various professional journals and the "Expedition research results" of this Proceedings volume. This introductory section provides an overview of operations, curatorial conventions, and general core handling and analysis.
