The buoy is moored off Sydney at a water depth of approximately 85m. This metadata record includes a down-loadable .pdf summary document which includes a map with numbered deployment locations and a listing of deployment number, location, water depth and deployment period. The Sydney buoy is a direction capable wave-rider buoy made by the Dutch company Datawell. The Directional Waverider buoy utilises a heave-pitch-roll sensor, two fixed X and Y accelerometers and a three axis fluxgate compass to measure both vertical and horizontal motion. An on-board processor converts the buoy motion to three orthogonal (vertical, north-south, east-west) translation signals that are transmitted to the shore station. The directional spectrum is also routinely transmitted to the receiving station for further processing. This buoy also collects sea surface temperature (SST) data from thermistors that are mounted inside the hull of the buoys, at the base of the buoy about 0.5m below the water surface. The wave and SST data are stored on the receiving station PC before routine transfer to Manly Hydraulics Laboratory via email. {"type": "Polygon", "coordinates": [[[151.39778, -33.7825], [151.4275, -33.7825], [151.4275, -33.76417], [151.39778, -33.76417], [151.39778, -33.7825]]]} 151.39778 151.4275 -33.7825 -33.76417 Oceans | Ocean Temperature | Sea Surface Temperature Oceans | Ocean Waves | Significant Wave Height Oceans | Ocean Waves | Wave Period Oceans | Ocean Waves | Wave Spectra Oceans | Ocean Waves | Wave Speed/direction sea_surface_wave_from_direction sea_surface_wave_maximum_wave_height sea_surface_wave_mean_crest_period sea_surface_wave_mean_wave_height sea_surface_wave_mean_wave_height_of_top_one_tenth sea_surface_wave_period_at_second_largest_peak_of_variance_spectral_density sea_surface_wave_period_at_variance_spectral_density_maximum sea_surface_wave_root_mean_square_amplitude_from_variance_spectral_density sea_surface_wave_root_mean_square_wave_height sea_surface_wave_significant_height sea_surface_wave_significant_wave_period sea_surface_wave_variance_spectral_density_zeroth_frequency_moment sea_surface_wave_zero_upcrossing_period sea_water_temperature Link to download netCDF data file - wave data documentDigital HTML Link to download netCDF data file - SST data documentDigital HTML Sydney buoy deployment summary documentDigital PDF Unnamed resource documentDigital audio/basic
