Barkley Upper Slope Vertical Profiler System Base Deployed 2018-07-01

The Vertical Profiler Platform Base was deployed on 2018-07-01 at Barkley Upper Slope. Upper Slope is a location within Barkley Canyon, which is located on the upper continental slope. This device is a Vertical Profiler System Base. A Vertical Profiler System (also known as an off-shore profiling system) is a mobile instrument platform that consists of a seafloor base unit and an instrument package that floats on a tethered cable. A winch on the base unit raises and lowers the instrument package. Cable spooled from the base is long enough for the instrument package to extend to the surface, collecting data throughout the water column. 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.

垂直剖面仪平台基座（Vertical Profiler Platform Base）于2018年7月1日部署于巴克利上斜坡区域。上斜坡是巴克利峡谷内的一处子区域，而巴克利峡谷地处大陆坡上部。该设备即为垂直剖面仪系统基座。垂直剖面仪系统（Vertical Profiler System，亦称近海剖面系统）是一类移动式科考仪器平台，由海底基座单元与系留缆绳搭载的漂浮式仪器载荷舱组成。基座单元上的绞车可实现仪器载荷舱的升降作业。基座放出的缆绳长度足以让仪器载荷舱抵达海面，可对整个水柱剖面进行数据采集。该系统依托固定式平台完成部署。本次部署获取的观测数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享；数据质量控制与衍生数据产品的生成均遵循行业既定规范。
