IOOS Glider - ng448-20180701T0000

Deployment of a Littoral Battlespace Sensing (LBS) glider owned and operated by the Naval Oceanographic Office (NAVOCEANO). This glider was deployed in the Gulf of Mexico. LBS gliders collect temperature and salinity profiles in the water column. These gliders were provided and operated by the Naval Oceanographic Office (NAVOCEANO) and are part of a larger effort to deploy and operate over 100 gliders simultaneously. Data collected by these Littoral Battlespace Sensing (LBS) gliders is assimilated for use in underwater ocean forecasts that support a wide range of naval operations.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)...

本数据集涵盖由美国海军海洋局（Naval Oceanographic Office，缩写NAVOCEANO）所有并运营的近岸战场感知（Littoral Battlespace Sensing，简称LBS）水下滑翔机的部署任务。该滑翔机部署于墨西哥湾海域。此类LBS水下滑翔机可采集水体剖面内的温度与盐度剖面数据。这批滑翔机均由美国海军海洋局（NAVOCEANO）提供并运营，属于一项同步部署并运行超100台滑翔机的大型项目的组成部分。此类LBS水下滑翔机采集的数据会被同化，用于水下海洋预报，以支撑各类海军作战任务。
