Comments:
* L-9-81-AA Lines 4, 8, 32, and 39 were provided in two parts, as two segy
files each. These parts were renamed lines 4a, 4b, 8a, 8b, 32a, 32b, 39a,
and 39b. The nav for each original line was split up to match the renamed
parts. Before GMA processing, the trace headers of line 10 were edited to
fix bad cdp’s and set delrect=0, and those of line 4b were edited to fix a
bad cdp. Lines 32-29 had cdp’s mistakenly recorded in the ffid trace
headers. This was also corrected prior to GMA processing. Line 31 is
corrupted and therefore could not be processed. This cruise was reprocessed
in two parts—east and west—as a workaround to GMA’s inability to handle
datasets that cross the international dateline.
