Description: Technical work this period has spanned three areas. The first of these is VHF Acoustics. During this time period, the Principle Investigator prepared for and conducted a VHF acoustics test in a wave tank at the Scripps Institution of Oceanography. The work, conducted in collaboration with and with the support of Dr. Grant Deane at the Scripps Institution of Oceanography yielded a rich data set characterizing the scattering of VHF acoustic signals from wind generated surface waves. The data has been quality checked and the first of the data has been analyzed. Results are described in the Major Accomplishments and Results and Recommendations sections of this report. This work falls under Research Task 2 from Section 2.2 of the Technical Approach and Justification. The first public presentation of these results will be at the 170th meeting of the Acoustical Society of America in Jacksonville, FL in November 2015. In parallel, the Principle Investigator continues to work with vendors to develop a new field deployable system for collecting VHF acoustic data in a wide range of environments.
