IOOS Glider - gp_365-20160627T1535

The global component of the OOI design includes a network of moorings at critical, yet under-sampled, high-latitude locations such as Station Papa in the North Pacific. Moorings located at Station Papa support sensors for measurement of air-sea fluxes of heat, moisture and momentum, and physical, biological and chemical properties throughout the water column.  The Global Station Papa Array is a combination of fixed platforms (moorings) with moored profilers to address the requirement to sample the full water column and mobile platforms (gliders) that provide simultaneous spatial and temporal sampling capabilities. The array is composed of a subsurface Global Profiler Mooring made up of two wire-following profilers, one operating from ~300 m to 2200 m and the second from ~2200 m to 4000 m. Two Flanking Moorings form a triangular array ~40 km on a side. These flanking Moorings have their uppermost flotation at ~20 m depth and instruments at discrete depths along the mooring line to a depth of 1500 m.  Open-Ocean Gliders sample within and around the triangular array equipped with acoustic modems to relay data from the Flanking Moorings to shore via satellite telemetry. Profiling Gliders sample the upper water column near the Apex Profiler Mooring.  The array at Station Papa is occupied in coordination with the National Oceanic and Atmospheric Administration (NOAA), which maintains a surface mooring there. As one of the oldest oceanic time series sites, with surveying conducted in the area since 1949, Station Papa is an important location within the global network of OceanSITES.cdm_data_type = TrajectoryProfileVARIABLES:trajectory (Trajectory Name)wmo_idtime (Profile Time, seconds since 1970-01-01T00:00:00Z)latitude (Profile Latitude, degrees_north)longitude (Profile Longitude, degrees_east)profile_idtime_uv (Depth-averaged Time, seconds since 1970-01-01T00:00:00Z)lat_uv (Depth-averaged Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)u (Depth-averaged Eastward Sea Water Velocity, m s-1)v (Depth-averaged Northward Sea Water Velocity, m s-1)...

海洋观测倡议（Ocean Observatories Initiative，OOI）设计的全球组成部分包含一套锚系观测网络，布设于北太平洋帕帕站（Station Papa）这类关键但采样不足的高纬度海域。位于帕帕站的锚系系统搭载多类传感器，可测量海气间的热、水汽与动量通量，以及整个水柱的物理、生物和化学属性。

全球帕帕站阵列（Global Station Papa Array）由固定平台（锚系）与锚系剖面仪组合而成，可满足全水柱采样需求；同时搭配移动平台（滑翔机），实现同步的时空采样能力。该阵列由一套水下全球剖面锚系组成，该锚系搭载两台沿缆线运动的剖面仪：一台工作深度范围约300米至2200米，另一台约2200米至4000米。两台侧翼锚系构成边长约40公里的三角阵列。这些侧翼锚系的最上层浮体设置于约20米水深，锚系缆线上的仪器布放于离散深度点位，最大探测深度达1500米。

开放式海洋滑翔机（Open-Ocean Gliders）在三角阵列内部及周边开展采样，搭载声学调制解调器，可通过卫星遥测将侧翼锚系的数据回传至岸基。剖面滑翔机（Profiling Gliders）在顶端剖面锚系附近的上层水柱开展采样。

帕帕站阵列的布放与美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）协同开展，该局在此处维护一套水面锚系。作为历史最悠久的海洋时间序列观测站点之一，该区域自1949年起便开展调查工作，帕帕站是全球OceanSITES观测网络中的核心站点。
