Abstract:
Cosmogenic beryllium-10 activities have been measured in marine accumulations of up to about 6 m.y age by conventional beta counting technique and by accelerator mass spectrometry. The two sets of data at 10Be levels of 109-1010 atoms/g agree within the absolute errors of the two methods. The detection limit for 10Be by the accelerator mass spectrometry is about five orders of magnitude lower than that with the beta counting method.

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1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions.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