Data Archive

Data generated at the LacCore Facility and sample metdata are permanently archived and available for distribution following NSF data access policies.

Data include:

• Core and subsample metadata
• Core images and image-derived color data
• Lithologic descriptions
• Smear slide descriptions
• Multisensor core logger data
  • Magnetic susceptibility (loop and point sensors)
  • Gamma density
  • p-Wave velocity and amplitude
  • Electrical resistivity
  • Natural gamma radiation
  • Color reflectance spectrophotometry
• XRF core scanner elemental data
• X-radiographic core images
• X-radiographic computed tomography (CT) slices and 3D reconstructions
• Subsample analytical data: grain size, loss on ignition, TIC/TOC/TC, biogenic silica, water content, etc.
