Glider observations of internal waves and internal tides near Luzon Strait

Another set set of sustained observations was made by gliders from 7 overlapping missions, April 2007 through July 2008. A particular focus is high frequency internal waves, where the operational definition of high involves periods shorter than a glider profile taking 3-6 hours. Internal wave vertical velocity is estimated from measurements of pressure and glider orientation through two methods: (1) use of a model of glider flight balancing buoyancy and drag along the glider path, and (2) high pass filtering of the observed glider vertical velocity. By combining high frequency vertical velocities from glider flight with low frequency estimates from isopycnal depth variations between dives, a spectrum covering 5 decades of frequency is constructed. A map of the standard deviation of vertical velocity over the survey area shows decay from the Luzon Strait into the Pacific. The growth of high frequency vertical velocity with propagation into the South China Sea is observed through two two-week time series stations. The largest observed vertical velocities are greater than 0.2 m/s, and are associated with displacements approaching 200 m. The high frequency waves are observed at regular intervals of one day as they ride on the diurnal tidal internal waves generated in the Strait.
