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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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（National Oceanic and Atmospheric Administration National Centers for Environmental Information, NOAA-NCEI）从期刊论文、技术报告及其他机构的未公开资料中，汇编构建了NOAA-MMS海洋矿物地球化学数据库。该数据库在当时是全球范围内覆盖范围最广的铁锰矿床数据汇编成果。由于其最初采用的专有格式与现行标准不兼容，阿尔弗雷德·魏格纳研究所（Alfred Wegener Institute, AWI）与美国国家海洋和大气管理局（NOAA）共同决定，将这批遗留数据转录至PANGAEA数据库。本次数据迁移还针对可获取的原始数据源开展了细致校核，并补充编码了NOAA-MMS数据库未涵盖的辅助信息（如样品描述、分析方法等）。
