Abstract:
A taut-wire subsurface buoy system was designed and used in 300 feet of water over the northeastern shelf of the Gulf of Mexico offshore from Panama City, Florida for obtaining nearly continuous in situ current measurements at two water depths during the period of 0600 C.S.T. on 13 June 1965 to 1200 C.S.T. on 26 June 1965. Spectral and harmonic analysis were performed on these measurements to determine the dominant tidal components present in the northward and eastward components of these current measurements. Small diurnal tidal currents rotating contra solem were found to exist with little or no indication of semi-diurnal tidal currents present in the data. The eastward and northward components of the diurnal tidal currents were found to have amplitudes of 5.15 cmsec. and 2.28 cmsec., respectively. In comparison, the RMS for the total current at the same location had an eastward component of 10.3 cmsec. and a northward component of 5.4 cmsec. A study of the thermal structure of the area around the location of the buoy system was conducted using four vessels and a stationary platform. Little indication of internal tides was found by a preliminary study of the thermal data.
