This pic was taken on the Gary Chouest. The people in the pic are Willie Davis (Gun Mech), Dennis (APC) Zeke (Gun Mech). They are trying to "hot patch" a hole in an old Teledyne streamer section. This is for those of you that remember seismic when the terms "doodlebugger", "hot patch" and recording systems prior to the Syntron 480 were commonplace..... 
 
 
Note the extensive use of PPE.... lifejackets, hard hats, safety boots etc...
Cowboy seismic at its best !!!!!
