Abstract:

This report covers work done as a result of participation in the SWAPP cruise in conjunction with FLIP. We participated with the IOS vessel PARIZEAU and obtained extensive data sets using two rather novel approaches. We used Active sonar systems to detect bubble clouds and bubble size distributions, and Passive hydrophones to map the distribution and properties of breaking surface waves. Each of these approaches not only involved the development of specialized hardware, but also required development of novel signal processing schemes so as to handle the very high data rates. Each approach is described in sequence. A publication list resulting from this work is also included.
