Wave Packet Statistics

Forty-nine separate internal wave events were identified at Site B occurring between August 6 and August 30, 1998. Companion events were observed at Site A (occurring on average about 3.1 hours before Site B) and at Site C (occurring on average about 4.4 hours after Site B). The events at Sites A, B and C are numbered 1-49 based on the observations at Site B. Four additional events observed at Site A are numbered A1-A4. The arrival time of each wave packet was determined by the time at the peak of the first temperature oscillation and the number of oscillations in each packet was determined visually (see Temperature oscillation tables below). At Sites B and C the spatial configuration of the moorings allowed estimates of the direction and speed of wave propagation (see Wave characteristics tables below).

Site A

Arrival time of first peak in temperature (GMT), number of oscillations in packet, and temperature at first peak at 10, 20, 30, 40 and 50 m. (Temperature oscillations - Site A)

Site B

Arrival time of first peak in temperature (GMT), number of oscillations in packet, and temperature at first peak at 10, 20, 30 and 40 m. (Temperature oscillations - Site B)

Estimated beginning of wave packet (GMT) (typically 10-20 minutes prior to first peak in temperature), speed of propagation, direction of propagation and wavelength of waves determined from horizontal array (Wave characteristics - Site B)

Site C

Arrival time of first peak in temperature (GMT), number of oscillations in packet, and temperature at first peak at 10, 20, 30, 40 and 45 m (Temperature oscillations - Site C)

Arrival times of wave packet (GMT), speed of propagation, and direction of propagation determined from surface and subsurface mooring (Wave characteristics - Site C)
