The muitidisciplinary studies conductec by the i!fS collaboration with other aorgenizaticns during 19984 through 1967 wer of a much larger research initiative by the DNA ta batter understand dynamic properties cf strategic-scale nuclear bursts and the relevance if the Pacific Praving G-ounde (FFG* craters to issu o> strategic basing ard targeting of quclear weapons.
