Scattering Model Development

PhD student Miad Al Mursaline has been working on updating scattering models to include the pitch observed in longlines by the scientific echosounder.  Existing models do not describe the scattering physics adequately for this application, so he is conducting experiment and expanding theory to provide a way to better characterize line location, and also potentially estimate line pitch to improve modeling of droop.

Theory v. experiment at line pitch angles of 1 to 4 degrees, typical of kelp lines.
