Some of the files included here are so large that both ASCII and compressed versions are available. Some huge files such as vibrator performance lists are of no immediate use initially and are only available in compressed form. Large files' sizes are specified in kilobytes in parentheses.

Some coordinates (e.  g.  CDP bins) are only in UTMs. The UTM coordinates for corridor/line 1 are in extended zone 11, for lines 2A, 2B and 3 in extended zone 9.

Order of the lines in the "original" obs logs for lines 2A, 2B and 3:

TAPE#   NewFFID   OrigFFID   1stStn   LastStn

Corridor 1

• Notes on survey data processing: in plain text, and an MS Word version
• SEGP1 survey data in uncompressed (896 k) and compressed format (328 k).
• Original observer's notes in compressed format (216 k)
• Original observer's notes with strings replaced to shorten the file (a list of replacements is included): compressed version (184 k)
• Processor's observer notes in uncompressed (432 k) and compressed (83 k) format
• CDP centers in uncompressed (608 k) and compressed format, plus corner points of the bin line.
• compressed daily reports (30 k)
• compressed vibrator performance lists (3624 k)

Corridors 2 and 3
Since the FFIDs were cyclical (SEGD data store them in BCD with an upper limit of 9999), new FFIDs were given to the data now stored in SEGY format. The old FFIDs have been stored in a separate header word. The following tables correlate the 2 sets of FFIDs and give IBM 3590 reel numbers besides shot stations and receiver station ranges.

• Line 2A (408 k)
• Line 2B (368 k)
• Line 3 (408 k)

There are no original observers's notes available for lines 2 and 3: They were interspersed with various other kinds of information and keep changing their format. Extracting this information in a "pure" form was deemed too time consuming.

Corridor 2
Line 2 was acquired in two parts as lines 2A and 2B. The two lines run at approximately right angles. They crossed each other near Watson Lake, Yukon. Original observer's notes are only made available in a compiled form; the true originals are too repetitive and mixed with Vibrator analyses and other info.

Line 2A

• Original obs log (296 k)
• Processor's observer notes (344 k)
• Shot survey file (672 k, SEGP1), skids (SEGP1), processor's survey file (312 k) and proessor's CcDP bin line

Line 2B

• Processor's obs log (272 k), Processor's observer notes (312 k)
• SEGP1 survey file (520 k, SEGP1), processor's survey file (272 k) and processor's CDP bin line

Corridor 3
This line follows the Canol road from Canol (Yukon/NWT border) to Whitehorse ...

• Processor's obslog (269 k), processor's tape log (1576 k)
• SEGP1 survey file (656 k), processor's survey file (296 k), processor's CDP bin line, skids in SEGP1 format (47 k)
• Local floppy index for corridors 2 and 3
