Model statistics of inertial shear from multi- year simulations at weathership 'Mike': currents, atmospheric forcing, internal waves, mixed layer, Norwegian Sea)
(NATO. SACLANTCEN, 1990/12)In this memorandum we focus on one of the most important environmental -
Development of barotropic models for the GIN Sea
(NATO. SACLANTCEN, 1991/03)Barotropic ocean models are developed for deep oceans, with arbitrary topography and basin geometry, on a sphere. A special adaptation is made for the Greenland-Iceland-Norwegian (GIN) Seas with closed lateral boundaries. ... -
The KRAKEN normal mode program
(NATO. SACLANTCEN, 1991/09)In the late 1970's several normal-mode models existed which were -
Surface measurements made during the Icelandic Current Experiment (ICE 89) from the R/V Alliance
(NATO. SACLANTCEN, 1991/10)Measurements of surface meteorology and sea temperature taken during the GIN '89A cruise of the research vessel Alliance are presented in the form of time-series plots. The cruise was in the southern Icelandic and Norwegian ... -
A simple deconvolution method for NAPOLI'85
(NATO. SACLANTCEN, 1991/10)An inverse filter (deconvolution in the frequency domain) is applied -
Atlantic inflow experiment GIN Sea Cruise'87 datareport: Part I: Tydeman hydrography: volume 1
(NATO. SACLANTCEN, 1991/12)The hydrographic data from the GIN 87-T cruise on board the HNLMS Tydeman are summarised in this data report. This cruise constituted the first cruise of the 1987 portion of the Atlantic Inflow Experiment, -
Atlantic inflow experiment GIN Sea Cruise'87 datareport: Part I: Tydeman hydrography: volume 2

Atlantic inflow experiment GIN Sea Cruise'87: Data report Part II: Circulation (Faeroe Channel)
(NATO. SACLANTCEN, 1991/12)This data report summarizes results of the Atlantic Inflow Experiment, -
An analytical study of source localization in shallow water by matched-field processing of horizontal arrays
(NATO. SACLANTCEN, 1992/08)Over the last few years a large number of studies have reported results of range-depth localization of sound sources by matched-field processing of vertical arrays in known environments. The performance of matched-field ... -
Perturbation theory applied to sound scattering from a rough sea-floor
(NATO. SACLANTCEN, 1992/09)Perturbation theory is applied to acoustic scattering from a rough sedimental sea-floor. Realistic -
Mapping ocean sediments by RBF networks
(NATO. SACLANTCEN, 1992/09)Interpolation of sparse measurements of ocean-sediment properties by generalized radial basis function (RBF) networks is proposed. An RBF -
Icelandic current experiment GIN Sea Cruise 88 data report: Hydrography and circulation: volume 1
(NATO. SACLANTCEN, 1992/09)The hydrographic and circulation data from the GIN '88 cruise on board the R/V Alliance are summarised in this data report. This cruise constituted the first component of the Icelandic Current Experiment, an observational ... -
Icelandic current experiment GIN Sea Cruise 88 data report: Hydrography and circulation: volume 2

An experimental study in forming a long synthetic aperture in the sea
(NATO. SACLANTCEN, 1992/09)Successful experimental testing of synthetic aperture techniques for sonar systems have been very limited and only few results, including very stable CW signals, have been published. These experimental results and theoretical ... -
Application of real data to sonar detection by neural networks
(NATO. SACLANTCEN, 1992/11)This memorandum describes the results of applying an artificial neural network for the detection of target echoes. The present study is a continuation of work conducted in 1989 in which a three-layer artificial neural ... -
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 ... -
SACLANT Undersea Research Centre - Research and Accomplishments 1975-1989
(NATO. SACLANTCEN, 1992/12)The SACLANT Undersea Research Centre, originally the SACLANT ASW Research Centre, was established in 1959 to provide scientific and technical advice and assistance to the Supreme Allied Commander Atlantic in the field of ... -
Surface measurements made from the R/V ALLIANCE during the Mediterranean aircraft-ship transmission experiment (MASTEX), June 1990
(NATO. SACLANTCEN, 1992/12)Measurements of sea-surface temperature, surface meteorology and atmospheric profiles taken during the June 1990 cruise of the R/V Alliance in the Aegean and Ionian Seas are presented in graphical form. True winds, net ... -
Ocean currents in the Iceland-Faeroe area, measured by a bottom-mounted ADCP
(NATO. SACLANTCEN, 1992/12)Horizontal currents as a function of depth, measured by a bottommounted -
Hydrography of the Iceland-Faeroe Ridge during March 1992: environmental data during NORDIC 92
