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…

With fieldwork cancelled March through June, the WHOI KelpBot team focused on development of a prototype low-cost ARPA-E MARINER Echosounder DAQ Box (LC-EDB), based around the BlueRobotics Ping 120 kHz echosounder.   This system includes some of the features found in a commercial fish finder, in addition to logging pose data from an IMU (roll/pitch/yaw), GPS…
