Abstract

A total of 450 selected tweeks recorded in the nighttime during a period of September 2003 – May 2004, at Suva
(18.08oS, 178.3o E), in the south pacific region, have been used to estimate, the cutoff frequency of different modes, the total propagation distance, and the ionospheric reflection heights. Higher harmonics appeared predominantly in the post-midnight period. The cutoff frequency of different modes ranged from 1.79 – 1.62 kHz. Estimated nighttime ionospheric reflection heights varied from 80 – 95 km. The waveguide formed by the sea and the lower ionosphere offers less attenuation than that formed by the earth and the lower ionosphere.
