Barkley Canyon Mid-West Imaging Rotary Sonar Deployed 2012-06-02

The Kongsberg Mesotech Rotary Sonar 1171 (1108032) was deployed on 2012-06-02 at Barkley Canyon Mid-West. Barkley Canyon Mid-West is a location in Barkley Canyon near a canyon wall. At this location, benthic processes, biodiversity, and 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.编号为1108032的康斯伯格梅索泰克（Kongsberg Mesotech）旋转声呐1171于2012年6月2日部署于巴克利峡谷中西部（Barkley Canyon Mid-West）。该区域位于巴克利峡谷内邻近峡谷壁的位置，是开展底栖过程、生物多样性及沉积物动力学观测的研究位点。本设备为成像旋转声呐（Imaging Rotary Sonar，IRS），此类设备专用于水下测绘与剖面探测：其可发射锥形或扇形波束，作用距离与分辨率取决于设备的工作频率与配置方案。设备会记录并分析反射信号（即回波），以此生成覆盖扫描区域的成像结果，其中包含声呐与被扫描物体之间的距离信息。本次部署将该声呐搭载于固定平台之上，此次部署获取的原始数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施完成归档并对外开放，相关数据遵循既定行业规范完成了质量管控，并同步产出了配套的衍生数据产品。
