Abstract:The proposed work will address the core physics underlying acoustic reverberation as related to properties of the ocean environment and properties of the acoustic sources, receivers and waveforms that make up ocean-going acoustic systems of interest to the U.S. Navy. Present day active acoustic… more
Abstract:The OASIS/WHOI team will design and develop a long-range under-ice acoustic navigation and telemetry system. The Phase I work has resulted in a much-improved model for under-ice acoustic propagation and an in-depth exploration of the potential for regional scale (200-500 km) acoustic navigation and… more
Abstract:The objective of the proposed effort is to develop and demonstrate a passive hearing protection that affords true sense of presence for normal sound with directionality. Existing hearing protection systems fall short of providing a true sense of situational awareness for the user and are therefore… more
Abstract:The proposed effort is focused on developing a passive field drying system termed as"DrySAF"that will allow marines to dry overnight their clothing system such as boots, uniform, etc. Oceanit will develop a hybrid nanocoposite material that has the capacity to absorb water rapidly from wet… more
Abstract:ABSTRACT: Oceanit will develop a working prototype module that will undergo testing with each category of Threat engagement. We will articulate a clear pathway forward to productization to include package design concepts that meet tactical and environmental considerations. BENEFIT: Dual Use… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
