The Office of Naval Research (ONR) Ocean Acoustics program supports research which addresses an understanding of the physics of the generation, propagation and scattering of narrowband 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 should be proposed to the appropriate environmental programs (e.g., Physical Oceanography and Littoral Geosciences and Optics). 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 appropriate environmental program officer.
Links to online annual reports for many ongoing and recently completed studies are provided at the left side of the page. These annual reports can provide a detailed view of the types of research sponsored by the program in recent years. The Ocean Acoustics Program contains two thrust areas. Brief descriptions of these thrusts are presented below.
- Shallow-Water Acoustics: This thrust's goal is to understand the propagation and scattering of acoustic energy in a shallow-water ocean environment. Areas of research include: shallow-water scattering mechanisms related to reverberation and clutter; seabed acoustic measurements supporting geoacoustic inversion; acoustic propagation through internal waves and coastal ocean processes and the development of unified ocean/seabed/acoustic models, including scattering from rough surfaces, biologics and bubbles; and penetration/propagation within the porous seafloor.
- 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. The effects of environmental variability induced by ocean internal waves, internal tides and mesoscale processes, and by bathymetric features including seamounts and ridges, on the stability, statistics, spatial distribution and predictability of broadband acoustic signals remain an area of high interest. Also of interest is the coherence and depth dependence of deep-water ambient noise.
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.
Planning Letter/Pre-Proposal and Proposal Process
Planning letters (also referred to as pre-proposals, white papers or letters of intent) are encouraged in advance of formal proposals for greater efficiency. 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, technical approach, relevant references, and an estimate of the funding requested. While our call for planning letters for the upcoming fiscal year have specific deadlines, unsolicited proposals and planning letters are accepted at any time throughout the year.
- May 1, 2013: Pre-proposal deadline (anticipate response soon after July 15)
- Aug. 15, 2013: Full proposal deadline: (unless otherwise negotiated)
Special Ocean Acoustics Awards
ONR awards graduate traineeship, postdoctoral fellowship and entry-level faculty awards in ocean acoustics. Requests should use the pre-proposal format with any additional guidance found in the Special Research Awards overview page.
