Caryn seamount (36° 42'N, 68° 02'W) was discovered in 1948 during Caryn cruise 1. During the summer of 1963 the Chain (cruise 36) occupied a dredge station on Caryn seamount. Caryn seamount (36° 42'N, 68° 02'W) was discovered in 1948 during Caryn cruise 1. During the summer of 1963 the Chain (cruise 36) occupied a dredge station on Caryn seamount. Manganese nodules, semiconsolidated mud, altered vesicular volcanics, and several glacial erratics were obtained from the western slope of the seamount between depths of about 3950 and 4300 m. The 1963 dredge haul by Chain, the first to obtain volcanic rocks, confirms the volcanic origin of the seamount. Previously, only manganese nodules had been dredged from Caryn, during cruise 21 of Chain.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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