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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.

1983年至1989年间，美国国家海洋和大气管理局国家环境信息中心（NOAA-NCEI）从期刊论文、技术报告及其他机构的未公开资料中，汇编形成了NOAA-MMS海洋矿物地球化学数据库。彼时，该数据集是全球范围内覆盖范围最广的铁锰沉积物（ferromanganese deposits）相关数据汇编。该数据库最初以专有格式发布，与当前通行的数据标准不兼容，因此德国阿尔弗雷德·魏格纳研究所（AWI）与美国国家海洋和大气管理局（NOAA）共同决策，将这批历史遗留数据转录至学术数据仓储PANGAEA。本次数据迁移还辅以严谨的补充工作：若可获取原始资料，则对其进行逐一核查；同时对NOAA-MMS数据库未收录的辅助信息（如样品描述、分析方法等）进行编码处理。
