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.本数据集采集了亚速尔群岛法亚尔岛与皮库岛之间斜坡区域的38 kHz科研级回声探测数据。该数据集覆盖昼夜全时段，旨在测定该区域深海散射层的昼夜垂直迁移规律。所用换能器（transducer）安装于船体尾板附近，且浸入水面下0.5米处。
