IOOS Glider - Glider's Deepwater Hurricane Reconnaissance in the Gulf of Mexico - sedna- 20241001T0000

The proposed study will use broadband deep-water ambient sound field information collected by stationary and mobile (Slocum glider reconnaissance flights) passive acoustic monitoring platforms during a major hurricane passage to reconstruct the storm wind speed distributions and to quantify changes in oceanographic and acoustic environments during storms. Based on the newly collected data and Bayesian inversion technique, a range dependent surface source model relevant to hurricane conditions and the frequency-dependent sound attenuation model due to bubble clouds in the high-wind environment will be developed. In the future, underwater reconnaissance could provide a safe and cost-efficient addition or alternative to the expensive and risky NOAA reconnaissance flights into the hurricane eyecdm_data_type = TrajectoryProfileVARIABLES:conductivity (Sea Water Electrical Conductivity, S.m-1)crs (http://www.opengis.net/def/crs/EPSG/0/4326)density (Sea Water Density, kg.m-3)depth (m)instrument_ctd (CTD Metadata, 1)lat_uv (Depth-averaged Latitude)latitude (Profile Latitude, degrees_north)lon_uv (Depth-averaged Longitude)longitude (Profile Longitude, degrees_east)precise_lat (Precise Latitude, degree_north)precise_lon (Precise Longitude, degree_east)precise_time (seconds since 1970-01-01T00:00:00Z)pressure (Sea Water Pressure, hectopascal)profile_idqartod_conductivity_flat_line_flag (QARTOD Flat Line Test for sea_water_electrical_conductivity, 1)qartod_conductivity_gross_range_flag (QARTOD Gross Range Test for sea_water_electrical_conductivity, 1)qartod_conductivity_primary_flag (QARTOD Primary Flag for sea_water_electrical_conductivity, 1)qartod_conductivity_rate_of_change_flag (QARTOD Rate of Change Test for sea_water_electrical_conductivity, 1)qartod_conductivity_spike_flag (QARTOD Spike Test for sea_water_electrical_conductivity, 1)...
