Digital Imaging for Siple Dome Ice Core Analysis, Antarctica

Entry ID: NSIDC-0413

[ Update this Record ]

Summary

Abstract: This data set contains high-resolution digital images of thin and thick sections cut from the 1003 meter Siple Dome A main ice core. The images are useful for crystal size and orientation analysis and bubble size, shape, distribution, and number density determinations. The data set contains several generations of images, taken between June 1998 and May 2005. An accompanying spreadsheet contains creation date information for each file. The data are available via FTP in Adobe Photoshop Document (.psd), and Tagged Image File (.tif) formats. Additional information is provided as a Microsoft Excel (.xls) spreadsheet.
