Lithology Image Strips Extraction for the Ocean Drilling Program
Project description
The Ocean Drilling Program drilled 653 seabed sites and recovered 236km of core in the years 1985-2003. The core recoveries were photographed, but on a frame in varying light conditions. Modern visualisation software requires image strips, which today are scanned electronically. This project extracted image strips compatible with the modern scannings, from the legacy photos.
Objectives
The photos show in great detail the sediments, rock and structures that were sampled by the IODP in all oceans of the world, extending back over 120My of earth history.
The project objective was to bring this huge resource of valuable data up to modern standards and into high useability.
Time-line
2005-2009
Models in use
The Python programs for image analysis and strip extraction were written by CJ Jenkins, INSTAAR. They are available on request.
Results
Over 90% of the strips available were successfully extracted, in RGB color, usually at 40dpi (0.5mm) resolution. The collection - 2 TB of data - is now publicly available at servers and in core visualisation software.
- Borehole Research Group, LDEO, Columbia University, USA,
- ANDRILL, University of Nebraska, USA,
- PANGAEA Database, MARUM, Bremen, DEU,
- and their numerous database visitors.
By using the HPCC facility, the processing run time for the 36,000 photos and 1TB of input data was cut to one sixth.
Users
- Chris Jenkins, INSTAAR
Funding
Through the Consortium for Ocean Leadership, based on NSF funding to the Integrated Ocean Drilling Program.
Publications and presentations
Several public lectures and workshops have been given in the USA, Germany and Japan.
