Upper Slope South Imaging Rotary Sonar Deployed 2014-05-07

The Kongsberg Mesotech Rotary Sonar 1171 (1108032) was deployed on 2014-05-07 at Upper Slope South. Upper Slope South is a location within Barkley Canyon, which is located on the upper continental slope. 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.

康斯伯格美泰克（Kongsberg Mesotech）旋转声呐1171型（序列号1108032）于2014年5月7日部署于上斜坡南部区域。该区域位于巴克利峡谷（Barkley Canyon）范围内，而巴克利峡谷地处大陆架上部斜坡地带。此设备为成像旋转声呐（Imaging Rotary Sonar，简称IRS），此类设备主要用于水下测绘作业，涵盖成像与剖面测量两大功能。成像旋转声呐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及配置方案。反射信号（即回波）会被记录并分析，以生成扫描区域的可视化图像，该图像包含声呐与扫描目标之间的距离信息。本次部署的设备搭载于固定平台之上。此次部署获取的数据集已完成归档，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共享，所有数据均遵循既定规范完成质量保证，并配套提供衍生数据产品。
