Details

RC2607 was a 2-ship cruise with the R/V Thomas Washington.

Three types of data were collected

ACQ001

CDP: Conrad only reflection Lines 506, 522, 533-587 (CDP Lines 01-57)

The CDP and WAP segy files are archived as cdp gathers (25 meter bins). The shot number for each trace is in bytes 9-12 of the SEG-Y trace header

The line numbers assigned at sea were incorrect. Add 4 to the line number

in the cruise report to get the archived line number.

Details

RC2607 was a 2-ship cruise with the R/V Thomas Washington.

Three types of data were collected

ACQ002

WAP: Wide Aperture reflection lines 507-515, 523-532

(WAP Lines 01-13)

Conrad was the lead ship, followed by Washington at about 5200 meters.

The ships alternated shooting and the Conrad recorded all shots

The CDP and WAP segy files are archived as cdp gathers (25 meter bins). The shot number for each trace is in bytes 9-12 of the SEG-Y trace header

The shot nav files for WAP lines include the ship to ship range (antenna to antenna)for that shot and a flag indicating which ship was shooting (1-Conrad or 2-Washington)

The line numbers assigned at sea were incorrect. Add 4 to the line number

in the cruise report to get the archived line number

For RC2607_ACQ002 Conrad was the lead ship, Washington was ~5200 meters behind Conrad. Each ship shot once per min, one ship on the minute, the other on the half minute. Conrad recorded shots from both ships.
