IOOS Glider - Coastal & Global Scale Nodes (CGSN) - Coastal Pioneer NES - Profiling Glider 564 Deployed on 2021-04-03

The Pioneer Array is located on the continental shelf and slope south of Martha\'s Vineyard. The shelf-slope area is home to a highly productive ecosystem, and coincident with a persistent ocean frontal system where heat, salt, nutrients and other properties are exchanged between the shelf and the deep ocean. Data from gliders operating over the shelf contribute to understanding of the frontal system while those over the slope provide information about mesoscale features that may impinge on the front. 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:CDOM (Fluorometric CDOM Concentration, 1e-9)PAR (Photosynthetically Active Radiation, micromol.m-2.s-1)backscatter (Optical Backscatter (red wavelengths), 1.m-1)chlorophyll (Chlorophyll Concentration, kg.m-3)conductivity (Sea Water Electrical Conductivity, S.m-1)crs (http://www.opengis.net/def/crs/EPSG/0/4326)density (Sea Water Density, kg.m-3)depth (m)dissolved_oxygen (Dissolved Oxygen Concentration, micromol.kg-1)instrument_ctd (CTD Metadata, 1)instrument_flbbcd (Optical Backscatter, Chlorophyll and CDOM Fluorescence Sensor)instrument_oxygen (Dissolved Oxygen Sensor)instrument_par (Photosynthetically Active Radiation (PAR) Sensor)lat_uv (Depth-averaged Latitude, degrees_north)latitude (Profile Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)longitude (Profile Longitude, degrees_east)oxygen_saturation (%)pitch (Glider Vehicle Pitch Angle, degrees)platform (Platform Metadata, 1)precise_lat (Precise Latitude, degrees_north)...

先锋阵列 (Pioneer Array) 部署于玛莎葡萄园岛以南的大陆架与大陆坡海域。该陆架-陆坡区域拥有高生产力海洋生态系统，且与一处持续存在的海洋锋面系统重合——该锋面系统是陆架与深海之间热量、盐度、营养盐及其他海洋要素交换的关键区域。部署于陆架区域的滑翔机观测数据，有助于学界深入理解该锋面系统的特征；而部署于陆坡区域的滑翔机数据，则可提供可能影响锋面活动的中尺度海洋特征相关信息。
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，未经过任何校正或质量控制算法处理。
