Motion,Commotion,and Biophysical Connections at Deep Ocean Seamounts
Motion Commotion Biophysical Connections Deep Ocean Seamounts
2015/7/7
Seamounts attract the attention of physical oceanographers for a variety of reasons: seamounts play a special role in ocean biology; they may be hydrothermally and magmatically active and thereby feed...
Temporal variability of vertical zooplankton distributions is analyzed on timescales from minutes to days
based on 7 months of acoustic backscatter strength data in Lake Constance. A comparison with ...

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...

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...
