资源简介:
The Predictions of AcousticS with Smart Experimental Networks of GlidERS (PASSENGERS) project is a partnership between universities and the Naval Research Laboratory to improve the capability of data-assimilative ocean models to predict acoustic propagation in dynamic oceanography environments. It includes the deployment of teams of gliders in small (10 km) spatial footprints with integrated passive acoustics focused on mapping the physical and acoustic environment in the dynamic region of the Atlantis II Seamounts.cdm_data_type = TrajectoryProfileVARIABLES:commanded_ballast_pumped (c_ballast_pumped, cc)commanded_battpos (c_battpos, in)commanded_wpt_lat (c_wpt_lat, lat)commanded_wpt_lon (c_wpt_lon, lon)conductivity (Sea Water Electrical Conductivity, S.m-1)crs (http://www.opengis.net/def/crs/EPSG/0/4326)ctd41cp_timestamp (sci_ctd41cp_timestamp, seconds since 1970-01-01T00:00:00Z)density (Sea Water Density, kg.m-3)depth (m)dr_latitude (m_lat, degrees decimal minutes)dr_longitude (m_lon, degrees decimal minutes)gps_latitude (m_gps_lat, lat)gps_longitude (m_gps_lon, degrees decimal minutes)instrument_ctd (CTD Metadata, 1)instrument_hydrophone (Loggerhead LS1 Hydrophone)lat_uv (Depth-averaged Latitude, degrees_north)latitude (Profile Latitude, degrees_north)lon_uv (Depth-averaged Longitude, degrees_east)longitude (Profile Longitude, degrees_east)measured_air_pump (m_air_pump, bool)measured_altitude (Glider Altitude Above the Seafloor, m)measured_ballast_pumped (m_ballast_pumped, cc)...

声学预测与滑翔机智能实验网络(Predictions of AcousticS with Smart Experimental Networks of GlidERS,缩写PASSENGERS)项目由多所高校与海军研究实验室(Naval Research Laboratory)联合开展,旨在提升数据同化海洋模型(data-assimilative ocean models)在动态海洋环境中预测声传播(acoustic propagation)的能力。该项目将在10千米的小型空间覆盖范围内部署水下滑翔机(gliders)编队,集成被动声学(passive acoustics)设备,用于绘制亚特兰蒂斯二号海山(Atlantis II Seamounts)动态区域的物理与声学环境地图。
