Description
Summary:The objective of this project is to better understand the coupling of energy from explosions near the water surface. The Institute of Dynamics of the Geospheres (ITG) has provided unique historical hydroacoustic data from Russian archives, featuring various combinations of depths of explosion. and distances and depths of recording. We analyze and model peak pressure measurements and hydrophone records from two underwater and one above-water nuclear explosions in Novaya Zemlya, as well as digitized data set from 1OO-kg TNT explosions in a reservoir. Observations are compared with theoretical estimates of pressure coupling coefficients (EM-I manual). REFMS software predictions of shock waves from underwater explosions, and LLNL modeling results. The original document contains color images.
