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)...
