ARIS dataset: Three fish species

Imaging Sonar data collected using ARIS Explorer 1800 sonar using 1.8 MHz frequency. The sonar data were collected in an experimental pond (width: 6.5 m, length: 46 m, depth: 0.8 m). The velocity regime of the experimental pond was slow and relatively constant (0.08 – 0.14 m/s: measured using a SonTek FlowTracker). An imaging sonar (ARIS Explorer 1800, Sound Metrics Corp.; www.soundmetrics.com) was set facing across the pond and perpendicular to the current. The transducer was mounted 0.05 m below the water surface. Three fish species were in the pond at separate times: Atlantic salmon (number of fish in the pond n=43), striped bass (n=100), and American shad (n=13).

本数据集为采用ARIS Explorer 1800型声呐（工作频率1.8 MHz）采集的成像声呐（Imaging Sonar）数据。声呐数据采集于一处实验池塘（宽度6.5米、长度46米、水深0.8米）。该实验池塘的水流流态缓慢且相对稳定，流速范围为0.08–0.14 m/s，采用SonTek FlowTracker流速仪测量所得。本次使用的成像声呐（ARIS Explorer 1800，Sound Metrics公司；官网：www.soundmetrics.com）以垂直于水流的方向正对池塘对岸安装，换能器距水面0.05米。实验池塘内分时段投放了三种鱼类：大西洋鲑（池塘内鱼群数量n=43）、条纹鲈（n=100）以及美洲西鲱（n=13）。更多详细信息可参考https://doi.org/10.1002/tafs.10318<br><br>注意：作者可应要求提供更多原始数据，但受限于文件体积，本次公开的仅为20 GB的样本数据集。
