Barkley Canyon Hydrates Imaging Rotary Sonar Deployed 2022-07-29

The Kongsberg Mesotech Rotary Sonar 1171 (1206086) was deployed on 2022-07-29 at Barkley Canyon Hydrates. Barkley Canyon Hydrates denotes a gas hydrate field within Barkley Canyon. 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.

康斯伯格梅索泰克（Kongsberg Mesotech）旋转声呐1171（1206086）于2022年7月29日部署于巴克利峡谷水合物区（Barkley Canyon Hydrates）。巴克利峡谷水合物区指巴克利峡谷内的天然气水合物田。该设备为成像旋转声呐（Imaging Rotary Sonar，IRS），此类设备应用于水下测绘、成像与剖面探测领域：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频率与配置方案。反射信号（即回波）会被记录并分析，以生成包含声呐与被扫描物体间距信息的扫描区域成像结果。本次部署将声呐搭载于固定平台之上。本次采集的数据已完成归档，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，其质量保障与衍生数据产品均遵循既定规范流程。
