Time series variability in fluctuating ocean waveguides
(NATO. SACLANTCEN, 1999/07)
The variability of signals propagating through an uncertain sound speed structure is addressed. Signals are assumed to travel in a narrow band adiabatically in modes and to experience fluctuations in sound speed which are ...
On the predictability of subsurface sound speed from satellite-measured sea-surface temperature in the Mediterranean
(NATO. SACLANTCEN, 1996/01)
The report investigates the extent to which subsurface sound speed may be determined from satellitemeasured
High resolution geoacoustic inversion in shallow water: a joint time and frequency domain technique
(NATO. SACLANTCEN, 1998/12)
High resolution geoacoustic data are quired for accurate predictions of
Parameter estimation using multi-frequency range-dependent acoustic data in shallow water
(NATO. SACLANTCEN, 1996/11)
The estimation of all forward model parameters - geometric, geoacoustic,
Hydrographic measurements in the southern Iceland and Norwegian Seas during June and August, 1989
(NATO. SACLANTCEN, 1993/12)
This memorandum documents an extensive collection of CTD data made during two cruises in the region between Greenland and Norway
Passive ranging with the SNAP model: a performance study
(NATO. SACLANTCEN, 1987/07)
A passive ranging technique which uses SNAP, the SACLANT Centre's normal-mode model, is studied. An examination is made of the sensitivity of the technique to errors in the assumed sound
Oceanographic conditions in the Antalya Basin in water
(NATO. SACLANTCEN, 1998/07)
From an oceanographic survey of the Antalya Basin in February 1997 the following horizontal circulation pattern was found: The Asia Minor Current (AMC) was detached from the Turkish coast flowing to the southwest between ...
Celtic Duet - a joint SACLANTCEN/NRL shallow-water sea trial in Celtic Sea during July 1992: data summary
(NATO. SACLANTCEN, 1996/10)
In July 1992 a joint shallow-water sea trial was conducted in the
Principles and methods of core analysis at the SACLANT ASW Research Centre
(NATO. SACLANTCEN, 1967/08)
The methods and accuracy of measuring core parameters at the SACLANTCEN are described. Those for measuring sound velocity and electrical resistivity are explained in detail.
