    • A deep stepped thermohaline structure deep in the Mediterranean 

      Johannessen, Ola M.; Lee, Owen S. (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 

      Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (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 

      Grasso, Raffaele; Braca, Paolo; Fortunati, Stefano; Gini, Fulvio; Greco, Maria S. (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 

      Tait, Robert I. (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 ...
    • Oceanic layered microstructure and fronts 

      Johannessen, Ola M. (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 

      Alvarez, Alberto; Mourre, Baptiste (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 

      Del Balzo, Donald R.; Moseley, W. B. (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 ...
