Active Experiments

The Society of Exploration Geophysicists Y Format, or SEG Y, has been the accepted exploration industry data format for digital seismic data since 1975.  Originally a magnetic tape-centric format, SEG Y has evolved over the years to remain the data format industry standard for data analysis and processing.  The latest revision (revision 1 .pdf format) to the format was released in 2002. 

All data requests of PH5 format data sets are fulfilled as either SEG-Y or PASSCAL SEG-Y.

       The impetus to provide a new data format for archiving stems from the inherent limitations with respect to the use of SEG-Y as a data archiving format, limitations such as: requiring vetted meta-data prior to converting the data into SEG-Y files, un-editable meta-data within the file, and inflexible, static data gathers.

PH5, clearly a better choice as an archival data format.
