Current
Project Objectives
Improve knowledge of baseline population demographics, vital rates, and movement patterns of Cuvier’s beaked whales and fin whales. Examine what, if any, short term behavioral and/or vocal responses occur when exposed to sonar or explosions at different levels and conditions. Determine if exposure to sonar or explosives impact the long term fitness and survival of individuals or the population, species, or stock
Current
Project Objectives
Improve understanding of the long term trends in occurrence of marine mammals (e.g., minke, humpback, fin, Bryde's, Blainville's) on the PMRF range. Examine what, if any, acoustic and physical behavioral responses occur to Navy activities.
Current
Project Objectives
Conduct comprehensive investigations of stranded marine mammals throughout the Pacific Islands with emphasis on the Hawaiian and Mariana Island chains. This includes conducting necropsies of stranded animals, collecting and archiving samples, conducting disease screening, genetic testing, and analysis of historical data. The objective is to examine stranding patterns and causes of death for marine mammals in the Pacific Islands.No related blog posts to display

Experimental measurements of the peak pressure and sound exposure level (SEL) from underwater explosions collected 7 km off the coast of Virginia Beach, Virginia are presented. The peak pressures are compared to results from previous studies and a semi-empirical equation that is a function of measurement range and charge weight, and are found to be in good agreement. An empirical equation for SEL that similarly employs a scaling approach involving charge weight and range is also presented and shows promise for the prediction of SEL in shallow water.
