The Ocean Acoustics program supports basic research that addresses fundamental understandings of the physics relating to underwater sound.
Areas of interest include the generation, propagation, and scattering of narrow- and broadband acoustic and elastic waves in the temporally and spatially varying ocean environment. Research that uses acoustics solely as a tool to study other environmental processes or that addresses an applied problem should be proposed to the appropriate directed programs e.
ONR may jointly support such efforts when a better understanding of the relevant acoustical propagation and scattering mechanisms are central to the research.
In this case, the investigator could also seek coordination of support from the other program. Planning letters also referred to as preproposals, white papers, or letters of intent are encouraged in advance of formal proposals for greater efficiency.
Program Contact Information
Planning letters save time and provide a starting point for a dialogue with the appropriate program officer. A planning letter should be a short description not to exceed two typed pages including figures.
The planning letter should contain the following information: telephone number and email address of the originator, the goals and technical approach, relevant references, and an estimate of the funding requested.
While our calls for planning letters for the upcoming fiscal year have specific deadlines, unsolicited proposals and planning letters are accepted at any time throughout the year. ONR awards graduate traineeships, postdoctoral fellowships, and entry-level faculty awards in ocean acoustics.
Requests should use the preproposal format with any additional guidance found in the Special Research Awards overview page. In addition to the investments under these thrusts, we continue to maintain more modest investments in research related to acoustic communications, particularly focusing on understanding and exploiting channel capacity.

Skip to Content. Ocean Acoustics: A National Naval Responsibility The Ocean Acoustics program supports basic research that addresses fundamental understandings of the physics relating to underwater sound.
Special Ocean Acoustics Awards ONR awards graduate traineeships, postdoctoral fellowships, and entry-level faculty awards in ocean acoustics.
Research Concentration Areas The Ocean Acoustics program contains three thrust areas: Shallow-Water Acoustics: This thrust's aim is to understand propagation and scattering of acoustic energy in shallow-water ocean environments. Deep-Water Acoustics: This thrust addresses issues associated with low-frequency acoustic propagation, scattering, and communication over distances from tens to thousands of kilometers in the deep ocean where the sound channel may or may not be bottom limited.
How to Submit
Arctic Acoustics: The primary goal here is to understand the effects of changing Arctic conditions on acoustic propagation and ambient noise, particularly in under-ice environments.
The thinning ice in the Arctic may result in reduced transmission loss compared to that observed during earlier investigations. The effects of environmental variability induced by ocean internal waves, internal tides, and mesoscale processes, as well as by bathymetric features including seamounts and ridges, on the stability, statistics, spatial distribution, and predictability of broadband acoustic signals remain areas of high interest.

Also of interest is the coherence and depth dependence of deep-water ambient noise. Type of Funding Available Basic Research For More Information Links to online annual reports for many ongoing and recently completed studies are provided at the left side of this page. Name: Dr.
