Determination of Lagrangian Deformations from Analysis of Current Followers
Lagrangian Deformations Current Followers
2009/3/7
Methods are presented to determine Lagrangian deformations and turbulence statistics from current followers (drogues, neutrally buoyant floats, etc.). Such determinations allow general advection-diffu...
Temperature Anomalies Between San Francisco and Honolulu, 1966–1974, Gridded by an Objective Analysis
Temperature Anomalies San Francisco Honolulu
2009/2/23
Over the eight years of expendable bathythermograph observations from merchant ship transits between San Francisco and Honolulu have been analyzed to determine the nature of subsurface temperature ano...
On Coastal Trapped Waves：Analysis and Numerical Calculation by Inverse Iteration
Coastal Trapped Waves Numerical Calculation Inverse Iteration
2009/2/23
Waves of sub-inertial frequency in a continuously stratified ocean and trapped over a continental shelf and slope are considered. They form one infinite discrete sequence of modes with frequencies dec...
Stochastic analysis of a three unit standby system
busy-time GERT idle-time MTSF w-function
2009/2/19
This paper presents a stochastic analysis of a non-identical three-unit system
with one-unit as standby and the other two units online by a Graphical
Evaluation and Review Technique (GERT). In this ...
Stochastic Dynamic Analysis of Polar Sea Ice Variability
Polar Sea Ice Variability Stochastic Dynamic Analysis
2009/2/19
The analysis of Arctic (1966–76) and Antarctic (1973–79) sea ice data is presented, and a dynamical model based on white noise atmospheric forcing, local stabilizing relaxation and lateral diffusion a...
Some Eulerian-Scale Analysis Results：Eddy Terms in the Mean Heat, Momentum and Vorticity Equations
Eulerian-Scale Analysis Results Eddy Terms Mean Heat Vorticity Equations
2009/2/18
The question of the importance of mesoscale motions in the long time averaged ocean circulation is examined from the viewpoint offered by Eulerian scale estimates of the magnitudes of the explicit edd...
An Analysis of Arctic Sea Ice Fluctuations, 1953–77
Arctic Sea Ice Fluctuations polar cap digitized data
2009/2/13
Arctic sea ice data from the 1953–77 period are digitized onto a set of 300 monthly grids covering the polar cap. Each grid contains 1648 ice concentration points at a spacing of 1° latitude (60 n mi)...
The response of the surface current to the wind has been described at various times by quadratic and linear laws. The quadratic response leads to Ekman-type currents while the linear response may be i...
Effect of Sampling Rate and Random Position Error on Analysis of Drifter Data
Sampling Rate Drifter Data Random Position Error
2009/2/13
The central question discussed here is how the rate at which drifter positions are determined and the position errors affect the calculation of velocity, acceleration and velocity gradients such as di...

Bottom Friction Shallow Semi-Enclosed Basin Tides Setup Field Experiment Harmonic Analysis
2009/2/11
This paper is the first in a series reporting the results of a study of tides, setup and bottom friction in the Bight of Abaco, Bahamas. The paper describes three month-long field experiments. employi...
An Integral Hydrodynamic Model of Upper Ocean Frontal Dynamics：Part I. Development and Analysis
Integral Hydrodynamic Model Upper Ocean Frontal Dynamics Development Analysis
2009/2/11
The paper develops and analyzes a model of frontal-scale dynamics applicable to established, persistent upper ocean density fronts. The effects of interfacial friction and mass entrainment arising fro...
An Analysis of Subtidal Current Fluctuations in the Middle Atlantic Bight
Middle Atlantic Bight Subtidal Current Fluctuations
2009/2/10
Subtidal current fluctuations in the Middle Atlantic Bight are examined from current-meter data collected in 1975 and 1976. Spectral analysis provides evidence for both locally wind-forced response an...
An analysis is made of HF radar measurements of surface currents in shallow water near the Georgia coast, and also of vertical profile measurements of current and density. The dominant structure is fo...
Method of Objective Analysis for Currents in a Lake with Application to Lake Ontario
International Field Year for the Great Lakes Lake Ontario
2009/2/9
The mean circulation in large takes is nearly nondivergent in character. This paper takes advantage of this fact to represent the flow field in terms of the transport streamfunction. The horizontal v...
