IOOS Glider - cp_387-20150111T1716

The Pioneer Array is located off the coast of New England, south of Martha\'s Vineyard. The Continental Shelf-Slope area off the New England coast is a highly productive area and one that is located at a dynamic intersection where ocean currents meet in weather-like fronts, and where nutrients, pollutants, and other properties are exchanged between the coast and the deep ocean. Data from the inshore, shelf area helps to examine exchanges between the shelf and slope and the shelf ecosystem, as well as provide broader insight into the issues of air-sea gas exchange, including Carbon Dioxide. In order to provide synoptic, multi-scale observations of the outer continental shelf, shelf break region, and continental slope, the moored portion of the Pioneer Array is supplemented by six Coastal Gliders. The role of the Coastal Gliders is to monitor the mesoscale field of the slope sea and outer shelf, resolving rings, eddies and meanders from the Gulf Stream as they impinge on the shelf break front.  The AUVs are the primary tools for resolving cross- and along-front eddy fluxes due to frontal instabilities, wind forcing, and mesoscale variability.  This dataset contains raw Slocum glider data parsed directly from the native glider file format.  No corrections or other quality control algorithms have been applied.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)latitude_qc (latitude Variable Quality Flag)longitude_qc (longitude Variable Quality Flag)time_qc (time Variable Quality Flag)...

先锋阵列（Pioneer Array）坐落于新英格兰外海，玛莎葡萄园岛以南海域。
新英格兰沿岸的大陆架-斜坡区域属于高生产力海域，同时地处洋流以天气尺度锋面形式交汇的动态交汇区，在此区域海岸与深海之间会发生营养盐、污染物及其他物质的交换。
近岸陆架区域的观测数据，既可用于研究陆架与斜坡间的物质交换及陆架生态系统，也能为包括二氧化碳在内的海-气气体交换相关议题提供更广泛的科学认知。
为对外陆架、陆架坡折区及大陆斜坡开展同步多尺度观测，先锋阵列的锚系观测单元配套部署了6台沿岸滑翔机（Coastal Gliders）。沿岸滑翔机的功能为监测斜坡海域与外陆架的中尺度流场，解析墨西哥湾流（Gulf Stream）冲击陆架坡折锋面时形成的环流、涡旋与流系弯曲。
自主水下航行器（AUVs, Autonomous Underwater Vehicles）则是解析锋面不稳定、风强迫及中尺度变率引发的跨锋面与沿锋面涡旋通量的核心观测工具。
本数据集包含直接从原生滑翔机文件格式解析得到的原始Slocum滑翔机（Slocum Glider）观测数据，未应用任何校正处理或其他质量控制算法。
