C0002T, C0009A, C0020A). No consta en la portada si hay parámetros de perforación o mudlog: revisar /sio7/contents/. Exp 314 se titula 'LWD Transect'; la tecnología de logs de cada hole no se detalla. Avisos: nombres de fichero repetidos entre holes y tamaños expresados en 'length'. Exp 405 (JTRACK), citada en iodp.org, no aparece en este índice. jamstec.go.jp solo mostró un selector de idioma.",
