Andone LaveryMy research focuses on the development and use of acoustical techniques and platforms to study the physical and biological processes in the ocean. From the perspective of physical oceanography, I am interested in developing acoustic techniques to quantify mixing by internal waves, to characterize warm-core ring intrusions onto the shelf break, the shelf break front, double-diffusive layering, and to acoustically image and quantify shear instability, buoyant plumes, salt-wedge intrusions, and hydraulic jumps. From an acoustics perspective, where there is high stratification, there is typically a strong acoustic signal. From the biological perspective, I am interested in ecosystem acoustics, that is using acoustic techniques to resolve ecosystem processes at relevant spatial-temporal scales, for example to help quantify marine diversity, behavior, patchiness, size, abundance, biogeography, migration. Pelagic ecosystems are comprised of diverse organisms spanning many trophic levels, species, sizes, and shapes. The composition and distribution of different populations are generally heterogeneous and patchy over multiple temporal and spatial scales, and differentially influenced by behavior, predator-prey interactions, physical forcing over a range of spatial scales, and anthropogenic forcing factors (such as ocean acidification or fisheries).
I am particularly motivated by 1) questions that address bio-physical interactions, 2) helping to address questions that have more immediate applications to pressing fisheries management concerns, such as stock assessment and reducing by-catch, and 3) developing new integrated acoustical and optical platforms, including AUVs and deep-towed systems, to address these questions. I have various projects in these areas -- please contact me if you are interested in a summer of acoustical oceanography.
