Upper layer environmental parameters from CTD data - GIN '86 cruise
(NATO. SACLANTCEN, 1989/12)
The data from the SACLANTCEN June 1986 Cruise is analysed
Impact of uncertain environmental knowledge on the shallow-water transfer function
(NATO. SACLANTCEN, 1992/12)
It is assumed that the acoustic channel can be modeled as a linear time-invariant space-variant filter. In this case, from linear systems theory, it is known that the filter output, that is the predicted source signal ...
Instrumentation for crosshole geoacoustic measurements in unconsolidated sediments
(NATO. SACLANTCEN, 1994/06)
Research tools are described that enable direct measurements of sediment properties as a function of depth in unconsolidat,ed sediments. The first tool is a hole making device that sits on the sea floor and utilizes pneumatic ...
The application of coupled-mode theory to propagation in shallow water with randomly varying sound speed
(NATO. SACLANTCEN, 1987/06)
Sound propagation in the Baltic Sea cannot be described correctly by range independent propagation
Nowcasting and forecasting of sound velocity structure by ocean modelling
(NATO. SACLANTCEN, 1999/04)
The Harvard Ocean Prediction System (HOPS) is applied to an observed oceanographic data set in
A note on convergent zones
(NATO. SACLANTCEN, 1962/02)
An exact solution for ray paths near a sound channel with parabolic velocity profile is given for rays crossing the sound channel axis at small angles. The convergent zone for such rays for a source on axis is compared ...
Deduction fo synthetic temperature profiles from SST observations in the Iceland-Faeroe frontal region
(NATO. SACLANTCEN, 1996/01)
Subsurface temperature and sound speed profiles are generated from satellite SST observations and
Direct observation of the angle of intromission in marine sediment
(NATO. SACLANTCEN, 2001/06)
High porosity marine sediments like silty clays have the curious property that the speed of sound through its bulk medium is lower than that of the interstitial pore fluid. When a high porosity sediment is at the water ...
Water masses, sound velocity structure and circulation between the eastern Algerian Basin and the Strait of Sicily in October 1996
(NATO. SACLANTCEN, 2002/01)
The investigation is based on data collected between the eastern Algerian Basin and the Strait of Sicily and in the southern Tyrrhenian Sea. The major pathways of water masses are identified by the
