Overview of attributes

Binary data file:  Each profile is available as a binary file in Society of Exploration
Geophysicists SEG-Y format.  A SEG-Y file consists of 1) a 3200-byte file identification
record of EBCDIC encoded general information; 2) a 400-byte binary record with information
such as sample rate and record length specific to the data set; and 3) multiple records,
one seismic reflection trace per record.  Each trace record is preceded by a 240-byte
"trace header" containing information such as trace number and acquisition day and time
specific to each trace.  The trace data are represented as a time series of unitless
16-bit integer or 32-bit real numbers proportional to the pressure recorded at each
hydrophone.  The SEG-Y file is useful only if you have access to specialized software
designed to process and display seismic reflection data.
