Description/Abstract:
THE OBJECTIVE OF THIS PROJECT WAS TO MEASURE AND CORRELATE WITH EXISTI STING DATA THE PHYSICAL CHARACTERISTICS OF CRATERS ( RADIUS, DEPTH, LI P HEIGHT AND WIDTH, THROWOUT, AND PERMANENT VERTICAL GROUND-SURFACE DI SPLACEMENT SURROUNDING THE CRATER ) RESULTING FROM NEAR-SURFACE NUCLEA R DETONATIONS. PRIMARY PARTICIPATION WAS ON SHOTS KOA, CACTUS, AND FIG , THE ONLY LAND-SURFACE BURSTS OF OPERATION HARDTACK. DIMENSIONS OF TH E CRATERS WERE DETERMINED BY TOPOGRAPHIC, LEAD-LINE, AND AERIAL-STEREO GRAPHIC SURVEYS. SECONDARY PARTICIPATION INCLUDED FATHOMETER SURVEYS O F BARGE SHOTS LINDEN, OAK, YELLOWWOOD, BUTTERNUT, AND HOLLY. WHEN THE CRATER DIMENSIONS OF THE ABOVE SHOTS WERE COMPARED TO ADJUSTED DIMENSI ONS TAKEN FROM THE CRATER CURVES OF TM 23-200 IT WAS FOUND THAT SHOT C ACTUS AND SHOT FIG CRATER DATA COMPARED FAVORABLY, BUT THE SHOT KOA CR ATER DIMENSIONS WERE ENLARGED BECAUSE THE DEVICE WAS EMPLACED IN A WAT ER TANK. THE BARGE-SHOT CRATERS WERE LARGER THAN VALUES CALCULATED FRO M TM 23-200.
