Acoustics Program Internal Funding Allocation (IFA)

The Ocean Acoustics IFA funds research that expands understanding of the potential impacts of man-made ocean noise on marine animals in accordance with the requirements of the Marine Mammal Protection Act and the Endangered Species Act.  The research themes eligible for funding include: 1) levels and trends in ocean noise, 2) the 'soundscape' and noise animals are exposed to, 3) animals’ use of sound, 4) effects of noise exposure on auditory ability, behavior, physiology, and/or communication, and 5) mitigation measures needed to reduce noise exposure and/or its effects. Funded projects are listed below.
