31 Μαΐ 2024 · It proposes two methods for EOF reconstruction of measured sound speed profiles extended to full water depth by splicing measured sound speed profiles at non-full water depths with historical average sound speed profiles of the surveyed sea area.
Variations in temperature and salinity with water depth affect the rate of propagation loss. ... View in full-text. Context 2. ... of the better known features of deep water propagation is...
15 Μαρ 2022 · The structure of a sound speed profile (SSP) in deep water causes refraction of sound rays and Convergence Zones (CZs) of high intensity where the rays focus at shallow depth. Study of sound field characteristics in the CZs has always been the focus of deep-water acoustics research.
A sound speed profile shows the speed of sound in water at different vertical levels. It has two general representations: tabular form, with pairs of columns corresponding to ocean depth and the speed of sound at that depth, respectively.
1 Αυγ 2018 · Sound Speed Profile (SSP) is the key factor affecting underwater acoustics and it is of great value to obtain SSP in near real-time. In this paper, the sea surface data were used to reconstruct the SSP with the single empirical orthogonal function regression (sEOF-r) method in a global scale.
22 Μαρ 2022 · Having quantified the sound speed variations in each target area and for multiple depth levels, we found that climate-change-induced sound speed variations are substantial, reaching up to 1.5% (approximately 20 m/s) and exceeding the SS seasonal variability.
