LacCore History
• Limnological Research Center (LRC): 1959 -• provided many services prior to LacCore
LacCore History
• Limnological Research Center (LRC): 1959 -• provided many services prior to LacCore
• Repository founded at U of MN coincident with first GLAD project (2000)
LacCore History
• Limnological Research Center (LRC): 1959 -• provided many services prior to LacCore
• Repository founded at U of MN coincident with first GLAD project (2000)
• Need for core processing capacity• Equipment upgrades
LacCore History
• Limnological Research Center (LRC): 1959 -• provided many services prior to LacCore
• Repository founded at U of MN coincident with first GLAD project (2000)
• Need for core processing capacity• Equipment upgrades
• Expand scope to include smaller projects (2003)
LacCore History
•Facilities/equipment driven by Global Lake Drilling (GLAD) program
• Encourage use by other researchers• Adapt to needs of all projects at all scales• Support all phases of research

a. Physical curation: storage, labeling
b. Metadata / database management
c. Sample preservation / management
d. Depth scale generatione. Sampling
Repository PolicyAccession old or new cores,
given:• Adequate metadata• Known sampling history• Good condition
Repository PolicySampling moratorium• Two years from core retrieval• Original PIs only• At conclusion: Cores available
for sampling, ICD data & images made public
Repository PolicySample requests• Core IDs, depths, spl volume• Purpose / intended research• Sampling protocol
Collection• 10,400 m of core (stored at
LacCore)• 8,400 m drill cores• 2,000 m short cores
Future: • 2,500 m El’gygytgyn• Accession old collections
3320 ft2 / 310 m2
Virtual Repository• Store metadata / data for cores
not located at LacCore• Rapid assessment of previous
work done in a geographical region, or on a proxy
• Possible sample access• Simplify transition to
permanent storage
DatabaseStores all metadata for
expeditions, holes, cores, sections, samples; analytical data
