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 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

康斯博格梅索泰克（Kongsberg Mesotech）旋转声呐1171型（编号1108032）于2012年6月2日部署于巴克利峡谷中西部区域。巴克利峡谷中西部是巴克利峡谷内紧邻峡谷岩壁的一处观测区域，该区域针对底栖过程、生物多样性及沉积物动力学开展相关研究与观测工作。本设备为成像旋转声呐（Imaging Rotary Sonar, IRS），此类设备是用于水下测绘的专用装置，可开展成像与剖面测量作业。成像旋转声呐可发射锥形或扇形波束，其探测范围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，该结果包含声呐与扫描目标间的距离信息。本次部署将该声呐搭载于固定平台之上。此次部署获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放，且遵循既定规范完成了质量保障流程与衍生数据产品的制备工作。
