[SCG56-09] GANSEKI: Maintaining Accessibility of JAMSTEC Rock Samples and Associated Information
Keywords:Rock sample, On-line database, curation
Most of rock samples are fairly durable for long-time archiving as a resource for scientific research. Even if decades have passed since a rock sample was collected, one can still utilize it to carry out a research using modern techniques. It is important for utilizing such old samples that there is abundant information, such as sampling date, location, surrounding geometry, geological occurrence, who was the initial user, how samples are collected, for what purpose they have done it, etc. If such information remains abundantly and maintained for easy access, public users, who were not in touch with sampling, can evaluate and utilize samples from a standpoint close to that of initial researcher who sampled them.
One of the strong points of JAMSTEC rock samples is that associated information such as metadata, video/photo data, geophysical observation data, cruise reports and so on were collected simultaneously with rock sampling and many of them are still accessible even for old cruises. These associated information is accessible at databases introduced in "NUUNKUI" data site, in which GANSEKI itself is also included .
Individual sample information on GANSEKI is directly linked to online information, which is selected for its importance for rock sample usability. Among NUUNKUI data site, cruise and dive information on DARWIN, video/photo data on J-EDI are especially important for GANSEKI [4, 5]. As for the visualization service of submersible dive tracks which used to be available on previous JDIVES virtual exploration system, JAMSTEC is now implementing similar functions into the J-EDI system.
