Today's photo, 'Dune Shaking' was taken close to the location of yesterday's. It shows a side view of the four vibrators with the dunes in the background.
Today's photo, 'Calanscio Vibroseis' shows our seismic line stretching out from one set of dunes and across a plain towards another distant dune line.
So here's a wider shot of the end of the line. Well, not the end actually, more of a hiatus. The line continued up here on the top of the escarpment but all the trucks had to drive around to the nearest wadi or road we cut that provided access.
Things are looking down or, perhaps more appropriately, I'm looking down on things. Western Libya, 1990, and four Birdwagen Mark III's with Failing Y1100 vibrators approach the bottom of the escarpment.
Four in a Row is an expanded view of yesterday's photo (and also the photo I processed in the soon to be released Topaz Clarity.
On this survey we were using four Failing Y1100 vibrators mounted on International 6x6 trucks as our energy source. In this photo you can see the four vibrators shaking the ground and carving their way through the maize. In the foreground a spare fifth vibrator sits idle, ready to go to work if one of the other four breaks down. In the background are the Schoonspruit/Skoonspruit grain silos.
