Measurement and quantification of acoustic energy radiated into the ocean from a near surface airborne explosion (Project #LMR-80) COMPLETED
Principal Investigators: David Dall'Osto, Peter H. Dahl
This project will collect and provide to the Navy a set of well-documented and calibrated measurements of the underwater and airborne acoustic field produced by explosions that occur less than 10 meters above the surface of the water. Results will improve the accuracy and verification of the Navy Acoustic Effects Model (NAEMO)-based predictions of underwater sound fields from in-air explosives at both close and long range.

Collection of in situ Acoustic Data for Validation of U.S. Navy Propagation Models of Ship Shock Trial Sound Sources (Project #LMR-48) COMPLETED
Principal Investigators: Kerri Seger, Shyam Madhusudhana and Holger Klinck
This project collected relevant in situ data on the acoustic shock wave propagation during the full ship shock trial of the new Navy aircraft carrier, USS Gerald R. Ford (CVN-78). The data is being used to validate the underlying acoustic propagation model used within the Navy Acoustic Effects Model (NAEMO).

Multi-spaced Measurement of Underwater Sound Fields from Explosive Sources (Project #LMR-35) COMPLETED
Principal Investigator: Peter Dahl
This project conducted calibrated underwater acoustic field measurements associated with explosive detonations, which will be used to update the Navy’s Acoustic Effects Model.
