Strait of Georgia East Profiling Sonar Deployed 2010-02-20

The Imagenex 881A Profiling Sonar 3898 was deployed on 2010-02-20 at Strait of Georgia East. Strait of Georgia East refers to an eastern area of the Strait of Georgia. This device is a Profiling Sonar. Profiling sonars are devices used in underwater profiling where quantitative measurements are required. A profiling sonar transmits a very narrow, conical beam that generates one point per ping, providing very high resolution. 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.Imagenex 881A型剖面声呐（Profiling Sonar）3898于2010年2月20日布放于乔治亚海峡东部（Strait of Georgia East），该区域指代乔治亚海峡（Strait of Georgia）的东部片区。该设备为剖面声呐，此类设备专用于需开展定量测量的水下剖面探测场景。剖面声呐发射极窄的锥形波束，每个声呐脉冲（ping）可生成一个测点，具备极高的空间分辨率。系统会记录并分析反射信号（即回波），以生成扫描区域的成像结果，该成像包含声呐与被扫描物体间的距离信息。本次布放作业搭载于固定平台完成，所获数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享；所有数据均遵循既定规范开展质量保证工作，并生成标准衍生数据产品。
