<abstract>
<gco:CharacterString>The major purpose of Leg 31 was the scrutiny of tectonic, sedimentologic, volcanic, paleontologic, and paleooceanographic processes operative in arc-marginal basin complexes along with a deciphering of basin history. The 12 sites ultimately occupied during Leg 31 all yielded significant new data bearing on the nature and evolution of the West Philippine Basin, Shikoku Basin, and Sea of Japan. The major objective at sites 290 through 292 was to test the mode and age of origin of the West Philippine Sea with emphasis on the nature of the Central Basin Fault. Sites 294/295 were drilled far to the east of the Central Basin Fault zone in the thin sediment blanket covering deeper portions of the northeastern West Philippine Basin. The other sites were situated in the Sea of Japan.</gco:CharacterString>

<supplementalInformation>
<gco:CharacterString>From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.</gco:CharacterString>
