Barkley Canyon Axis Imaging Rotary Sonar Deployed 2012-06-02

The Kongsberg Mesotech Rotary Sonar 1071 (0711217) was deployed on 2012-06-02 at Barkley Canyon Axis. Barkley Canyon Axis is located within Barkley Canyon, where benthic processes, biodiversity, sediment dynamics are observed. This device is a Imaging Rotary Sonar. Imaging Rotary Sonars (IRS) are devices used in underwater mapping: imaging and profiling. An IRS transmits either conical or fan-shaped beam, and its range and resolution depends on the frequency and configuration of the device. Reflected signals, or echoes, are recorded and analyzed in order to develop an image of scanned area that includes information on the range between the sonar and the scanned object. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

康斯伯格梅索特（Kongsberg Mesotech）旋转声呐1071型（设备编号0711217）于2012年6月2日部署于巴克利峡谷轴区（Barkley Canyon Axis）。巴克利峡谷轴区地处巴克利峡谷（Barkley Canyon）境内，该区域为底栖过程、生物多样性及沉积物动力学的观测研究区域。该设备属于成像式旋转声呐（Imaging Rotary Sonar，IRS），此类声呐是用于水下测绘的专用设备，可实现成像与剖面测量。成像式旋转声呐可发射锥形或扇形波束，其探测量程与分辨率取决于设备的工作频率及配置参数。设备会记录并分析反射信号（即回波），以此生成扫描区域的成像结果，该结果包含声呐与扫描目标间的距离信息。本次部署的声呐搭载于固定平台之上。此次部署产生的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享；所有数据均遵循既定规范开展质量管控，并配套提供衍生数据产品。
