Abstract
Multiple components within and at the bottom of the water column can scatter acoustic signals, resulting in decreased sonar performance and compromised tactical decision making. Many of the biological organisms that contribute to acoustic clutter are also protected or managed species, integral to a fully functional marine ecosystem. In order to understand, predict, and model bottom and volume scattering, detailed descriptions of the spatial, spectral, and temporal variability of clutter elements are needed, along with reliable estimates of backscattering strength. All of these necessary components are dependent on marine wildlife databases. Efforts by several organizations have resulted in databases that provide pieces of the overall puzzle. Databases of distribution and abundance (Census of Marine Life’s OBIS‐SEAMAP), two‐dimensional movement (Census of Marine Life’s Tagging of Pacific Pelagics), and diving and movement behavior (Marine Wildlife Behavior Database) are examples of current, but disparate, ...
