资源简介:
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: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)depth (m)depth_qc (depth Variable Quality Flag)pressure (Sea Water Pressure, decibars)pressure_qc (pressure Variable Quality Flag)conductivity (Sea Water Electrical Conductivity, S.m-1)conductivity_qc (conductivity Variable Quality Flag)density (Sea Water Density, kg.m-3)...

先锋阵列(Pioneer Array)布设于玛莎葡萄园岛(Martha's Vineyard)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生态系统,同时存在一处长期存续的海洋锋面系统,在此区域陆架与深海之间会发生热量、盐度、营养盐及其他海洋要素的交换。
部署于陆架区域的滑翔机观测数据有助于增进对该锋面系统的认知,而陆坡区域的滑翔机数据则可提供可能影响锋面的中尺度特征相关信息。
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斯洛克姆滑翔机(Slocum glider)观测数据,未应用任何校正或质量控制算法。
