A deep stepped thermohaline structure deep in the Mediterranean
(NATO. SACLANTCEN, 1972/09)A deep stepped thermohaline structure has been observed in the Tyrrhenian Sea below the Levant ine water salinity maximum. The layers are remarkably homogeneous starting with a thickness of 10 m - 20 m at 600 m and thereafter ... -
Distributed underwater glider network with consensus Kalman filter for environmental field estimation
(CMRE, 2019/06)A distributed coordinated dynamic sensor network for optimal environmental field estimation is proposed and tested on simulated and real data. The architecture is used to distribute the estimation of 3D timevarying fields ... -
Environmental field estimation by consensus based dynamic sensor networks and underwater gliders
(CMRE, 2019/06)A coordinated dynamic sensor network of autonomous underwater gliders to estimate 3D time-varying environmental fields is proposed and tested. Each sensor performs local Kalman filter sequential field estimation. A network ... -
Internal oceanographic microstructure phenomena
(NATO. SACLANTCEN, 1975/10)This paper is concerned with the nature and causes of both fine structure and microstructure in the ocean. Following an account of the acoustic/oceanographic background to subject, the characteristics of fine structure are ... -
Observed sound velocity and temperature profiles in the Strait of Gibraltar during the passage of an internal wave
(NATO. SACLANTCEN, 1966/10)Sound velocity and temperature measurements taken from the sea-surface to 350 m depth, close to one spot over a 24-hour period revealed the passage of an internal wave of approximately 60 m amplitude. The effect of this ... -
Oceanic layered microstructure and fronts
(NATO. SACLANTCEN, 1971/12)This talk is divided into two parts: one deals with oceanic microstructure, with particular attention to the so-called "layered microstructure"; the other part is concerned with oceanic fronts. As an example of the latter ... -
Oceanographic field estimates from remote sensing and glider fleets
(CMRE, 2014/01)This work investigates the merging of temperature observations from a glider fleet and remote sensing, based on a field experiment conducted in an extended coastal region offshore La Spezia, Italy, in August 2010. Functional ... -
Random temperature structure as a factor in long-range propagation
(NATO. SACLANTCEN, 1975/10)A statistical description of horizontal thermal microstructure in anosotropic turbulence is developed for application with an existing acoustic propagation theory. The model predicts a temperature power density spectrum ... -
The effect of thermohaline variability on the exchange through Mediterranean straits
(NATO. SACLANTCEN, 1989/05)exchanges through straits. The primary assumption is that the exchange is determined by tlle pressure force created by the differing weights of tlle water columns on either side of the sill and by the continuity of mass ... -
The temperature structure in the upper layers of the Ligurian Sea and its seasonal variations
(NATO. SACLANTCEN, 1962/05)Water temperature measurements in the Ligurian Sea down to depths of 150 meters and meteorological data connected with these measurements for the period July 1960 to October 1961 are presented in the form of graphs and ... -
The temperature structure in the upper layers of the Ligurian Sea and its seasonal variations: supplement to SACLANTCEN technical report no. 8
(NATO. SACLANTCEN, 1964/04)Water temperature measurements, down to depths of 150 meters, and metereological data connected with these measurements carried out in t 1e Ligurian Sea in May and November 1962, are presented in the form of graphs and ... -
Upper layer environmental parameters from CTD data - GIN '86 cruise
(NATO. SACLANTCEN, 1989/12)The data from the SACLANTCEN June 1986 Cruise is analysed
