Core Description Sheets

Home | Acronyms | Contents | Methods | Maps | Core Data Table | Core Description Sheets | Digitized Core Logs | Grain-Size Data | Core Photographs | Field Logs | Metadata | Software



Note: Core logging standards are described in the Methods section ("Core Description Sheets").

   Core description sheets contain visual interpretations of lithology and structures, observed grain-size textures, physical characteristics, and sample location information. This identifying information and other characteristics are recorded on the paper copies of the core description sheets for each vibracore. The core description sheet files are available in JPEG (single page descriptions; cruises 07SCC04 and 07SCC05) or PDF (multi-page descriptions; cruise 87039) format.

   Although the vibracore description sheets used for the 87039 cores differ slightly from those used for the 7SCC04 and 07SCC05 cores, most of the column headers and recorded information is the same or similar. The following figures depict the two formats.

Cruises 07SCC04 and 07SCC05:

  • All core description sheet profiles for these 07SCC04 and 07SCC05 cruises are available as JPEG images in the core data table.

Cruise 87039:

CI87_description sheet preview

  • All core description sheet profiles are available as PDF images in the core data table.

Note: To view the core description sheets, an image preview application can be used for JPEG files and free Adobe Reader software is needed to access Adobe Acrobat (PDF) files. Files may also be viewed online with free Google Docs, if connected to the Internet. If you are unable to open any of these files, please contact Chandra Dreher (cdreher@usgs.gov).
