Echosounder data (38kHz) collected along the slope between Faial and Pico Island Azores in November and December of 2021

We collected 38 kHz scientific grade echosounding along the slope between Faial and Pico Island Azores. These data span night and day time periods and were aimed at measuring the diel vertical migration of the deep scattering layer in the area. The transducer was mounted near the transom of a boat and was submerged 0.5 meters below the surface.
