Modeling and simulation of a mini AUV in spatial motion
AUV kinematics model dynamics model motion control simulation
2011/9/9
Accurate modeling and simulation of autonomous underwater vehicle (AUV) is essential for autonomous control and maneuverability research. In this paper, a mini AUV? “MAUV-Ⅱ” was researched and the non...
The Amplitude of Baroclinic Wave Triads and Mesoscale Motion in the Ocean
Baroclinic Wave Triads Mesoscale Motion
2009/3/24
The finite-amplitude dynamics of a resonant triad of baroclinic waves in a slightly unstable baroclinic current is examined. The wave in the triad which is linearly unstable on the current is assumed ...
On Secondary Baroclinic Instability and the Meridional Scale of Motion in the Ocean
Secondary Baroclinic Instability Meridional Scale
2009/3/24
The stability of the marginally stable baroclinic wave in a uniform zonal shear flow is studied. Although the single, marginally stable wave on a horizontally uniform baroclinic current has little or ...
The Role of Vertical Motion in the Heat Budget of the Upper Northeastern Pacific Ocean
Vertical Motion Heat Budget of the Upper Northeastern Pacific Ocean
2009/3/7
A study of the heat budget of the upper northeastern Pacific Ocean demonstrates the importance of heat changes due to vertical motion. Bathythermograph observations are used to form time series of mon...
Comparison of Finite-Element and Finite-Difference Schemes. Part II：Two-Dimensional Gravity Wave Motion
Finite-Element Finite-Difference Schemes Two-Dimensional Gravity Wave Motion
2009/2/23
Irregular grid finite-difference techniques lead to equations similar to those obtained using finite-element techniques. The simpler finite-difference equations offer the advantage of greater computat...
Comparison of Finite-Element and Finite-Difference Schemes. Part I：One-Dimensional Gravity Wave Motion
Finite-Element One-Dimensional Gravity Wave Motion Finite-Difference Schemes
2009/2/23
The finite-element scheme requires more computational expense because it is time-implicit and because it requires a smaller time step than the finite-difference scheme. Simulations of normal mode osci...
A Spectral Theory of Nonlinear Barotropic Motion above Irregular Topography
Nonlinear Barotropic Motion Irregular Topography
2009/2/23
If a field of randomly distributed barotropic eddies interacts with underlying topographic features in a rotating reference frame, the flow is observed to develop, after a time the order of an eddy tu...
The Horizontal Coherency of the Motion of Summer Arctic Sea Ice
Horizontal Coherency Summer Arctic Sea Ice
2009/2/18
Four ice floes in the permanent arctic ice pack were instrumented during the summer of 1975. Spectral and cross-spectral analysis of the complex time series of the ice motion and of the surface winds ...
From current meter and satellite data, an unusual pattern of movement of the Gaspe Current was identified on two occasions in the summer of 1978. On the first occasion, the axis of the current moved o...
Coupling of Internal Wave Motion with Entrainment at the Density Interface of a Two-Layer Lake
Internal Wave Motion Two-Layer Lake Density Interface
2009/2/16
A solution is presented to the problem of a two-layer rectangular basin subject to a suddenly applied, uniform wind stress; Coriolis effects are ignored. The solution is obtained for the case in which...
Observations of Strongly Nonlinear Internal Motion in the Open Sea Using a Range-Gated Doppler Sonar
Strongly Nonlinear Internal Motion Open Sea Range-Gated Doppler Sonar
2009/2/13
A Doppler sonar has been developed at the Marine Physical Laboratory for the remote measurement of the upper ocean velocity field. The sonar transmits a 1° beam at 87.5 kHz, with 3 KW peak power. The ...
This paper examines the motion and propagation of an isolated of anomalous water on a beta-plane, considered previously by Nof (1981). His perturbation analysis is extended to show the following:
1...
Tidal Motion in Submarine Canyons—A Laboratory Experiment
Tidal Motion A Laboratory Experiment Submarine Canyons
2009/1/22
The reasons for the large-amplitude tidal motion observed in oceanic submarine canyons have been explored with a laboratory experiment. A barotropic tide was forced in a stratified tank, containing co...

Tidal Motion Stratified Inlet Boundary Conditions
2009/1/20
The method of characteristics is used to provide radiation-type boundary conditions appropriate to a portion of a two-layer inlet subject to tidal effects governed by one-dimensional shallow-water the...
A two-dimensional, two-layered frontal system is used to examine the wind-driven motion near a shelf-slope front. In the linear regime, the along-frontal current is characterized by barotropic perturb...
