This report contains the following abstracts: (1) upper ocean observations across an arctic transect, (2) evaluation of the SSXCTD fall rate equation, (3) observed anomalies in an upper arctic transect, and (4) measured transarctic acoustic travel times and model comparisons (complete article).
A single explosive shot at a range of 341.3 km in the Pole Abyssal Plain of the Arctic Ocean is used to assess the components of propagation loss for this region. The acoustic energy propagated between a satellite ice camp and the Fram II ice station in a water column of nearly uniform depth. Much of the observed energy interacted with the upper 200 meters of sediments along a path ...
Sound waves created by high-energy explosives were used to measure reverberation and backscattering in the Arctic Ocean. From an ice camp in the Beaufort Sea, signals were backscattered from the continental margin and other major features of the basin. An acoustic array was used to analyze the signals in azimuth. Based on these data we constructed charts of normalized backscatter level, which can be compared with known topography of the ...
