Minutes 1998 Curators of Marine Geological Samples Meeting

SOME INCIDENTAL ITEMS EMERGING FROM VARIOUS DISCUSSIONS

CORE WRAPPING - OSU routinely wraps cores with Handiwrap in preparation for multisensor logging and to slow core aging (esp. water loss) and mold growth. John Firth noted that ODP has begun a project to wrap its repository core collections, but whether or not all of the older, already dry, sediment cores will be wrapped is uncertain. One attendee commented that the amount of water contained in sponges was so small compared to water content of the core, that they were virtually useless in maintaining water content. Firth noted that D-tubes used are porous, not air tight as some of us had thought. Attendees also discussed possible generation of post-storage sulfides (sulfuric acid) in the cores causing destruction to calcareous components.

ARCHIVAL IMAGING - Whereas most agreed that digital imaging is fast and extremely useful for descriptive work, reports, and sample selection, COLOR, or in some cases black and white, PHOTOGRAPHY is the only method with sufficiently high resolution for ARCHIVAL PURPOSES.
