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.

康斯贝格梅索泰克（Kongsberg Mesotech）旋转声呐1071型（序列号0711217）于2012年6月2日部署于巴克利峡谷轴区（Barkley Canyon Axis）。巴克利峡谷轴区位于巴克利峡谷（Barkley Canyon）境内，该区域开展底栖过程、生物多样性及沉积物动力学相关观测。本设备为成像旋转声呐（Imaging Rotary Sonar，以下简称IRS），此类设备专用于水下测绘作业，可实现成像与剖面测绘功能。IRS可发射锥形或扇形波束，其作用距离与分辨率取决于设备的工作频率与配置方案。反射信号（即回波）会被记录并分析，以此生成覆盖扫描区域的图像，该图像包含声呐与扫描目标间的距离信息。该设备搭载于固定平台开展作业。此次部署获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外公开，且遵循既定规范完成了质量管控与衍生数据产品的制备。
