(Volume 2, Pages 590-629) Chemical composition of manganese nodules and ferromanganese crusts from the Carlsberg Ridge

Samples have been ignited at about 1000°C and leached in HCL.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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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.

样品已于约1000℃下灼烧，并经盐酸（HCL）浸取。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了NOAA-MMS海洋矿物地球化学数据库。在当时，该数据库是全球范围内关于铁锰矿床覆盖范围最广的数据集汇编成果。该数据库最初以专有格式发布，与现行标准不兼容，因此阿尔弗雷德·魏格纳研究所（AWI）与美国国家海洋和大气管理局（NOAA）共同决定将这批遗留数据转录至PANGAEA数据平台。本次数据迁移还辅以对可获取原始资料的严谨核查，并补充编码了NOAA-MMS数据库未收录的辅助信息（如样品描述、分析方法等）。
