| Data format: | The SEG-Y standard format (Barry and others, 1975) consists of the following: a 3,600-byte reel identification header, with the first 3,200 bytes consisting of an ASCII header block followed by a 400-byte binary header block, both of which include information specific to line and reel number; a trace data block that follows the reel identification header, with the first 240 bytes of each trace block consisting of the binary trace identification header; and seismic data samples that follow the trace identification header. in format SEG-Y Size: 1055 |

| Data format: | The GIS project used to create the trackline maps is composed of map documents, shapefiles, and metadata. The map documents, created with ArcView 8.1, are compatible with ArcGIS 8.1. The shapefiles, created with ArcView 3.2, may be viewed using other versions of ArcView or public domain software ArcExplorer, available from the ESRI website at <http://www.esri.com/software/arcexplorer/index.html>. in format map document, shapefile, metadata Size: 7.9 |
