IOOS Glider - sp039-20210225T2035

CORC (Consortium on the Ocean\'s Role in Climate) has been making observations of the California Current systems with moorings since 2008. In support of these mooring deployments, gliders have been used that serve as data shuttles to communicate with the underwater mooring gear, as well as collect additional data near or between the moorings. These glider operations are done by PI U. Send, and are in addition to repeat glider sections by PI D. Rudnick in the same general area. Glider data reported here are temperature and salinity, as well as column-average currents based on lateral glider displacement between dives.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)...

CORC（海洋气候作用联盟，Consortium on the Ocean's Role in Climate）自2008年起便依托锚系观测设备对加利福尼亚流系开展持续观测。为支撑该锚系部署任务，研究团队采用水下滑翔机作为数据中继平台，既可与水下锚定设备完成通信，亦可在锚点附近或锚点之间采集额外观测数据。本次滑翔机观测作业由PI U. Send负责实施，且是对同一海域内PI D. Rudnick所开展的重复滑翔机断面观测的补充。本数据集收录的滑翔机观测数据涵盖温度、盐度，以及基于滑翔机各潜次间横向位移计算得到的柱平均海流数据。
