摘要：

鱼探仪作为船载声学评估设备, 在生物资源走航调查与评估中具有重要作用, 其设备精度对评估结果具有较大影响。在鱼探仪的众多校准方法中, 标准球校准方法凭借其高效性和适用性优势, 已成为最常用的现场校准方法, 我国“雪龙2”号科考船采用该方法对船载Simrad EK80鱼探仪进行校准。本文基于中国第13次北冰洋科学考察, 系统阐述了船载鱼探仪的校准方法, 并总结了适用该方法的海洋环境特征, 以期为我国极地科考船舶的设备校准工作提供技术参考。

Abstract:

A scientific echo sounder is one of the main instruments used for acoustic surveying of living marine resources, and its appropriate calibration guarantees the reliability of the data it acquires. Among the different methods available for calibrating a scientific echo sounder, the approach used most widely in the field is the standard spherical calibration method. Taking the preparations adopted for 13th Chinese National Arctic Research Expedition as an example, this paper describes the application of the standard spherical calibration process to the calibration of the Simrad EK80 echo sounder onboard China’s R/V Xuelong 2 polar icebreaker, including the preparation, calibration procedure, and analysis of the calibration result. Following its successful calibration, the Simrad EK80 instrument was used to provide support for standardized implementation of the equipment used by other Chinese scientific research ships in the polar region.
