The Moving Boundaries of Sea Level Change:Understanding the Origins of Geographic Variability
Sea Level Change Geographic Variability
font style='font-size:12px;'>
2015/7/9
As ice sheets gain or lose mass, and as water moves between the continents and the ocean, the solid Earth deforms and the gravitational field of the planet is perturbed. Both of these effects lead to ...
Framed-Quadtree Path Planning for an Underwater Vehicle with the Task of Tracking a Moving Target
regular grid framed quadtree data structure algorithm efficiency
font style='font-size:12px;'>
2011/9/9
An autonomous underwater vehicle (AUV) must use an algorithm to plan its path to distant, mobile offshore objects. Because of the uneven distribution of obstacles in the real world, the efficiency of ...
Using a linear array to estimate the velocity of underwater moving targets
underwater velocity measurement linear array direction of arrival (DOA) deterministic maximum likelihood signal phase matching
font style='font-size:12px;'>
2011/9/13
A new method uses a linear array that takes advantage of underwater physical sound fields to estimate the velocity of an underwater moving target. The mathematical model was established by considering...
Observation of the Structure on Moving Gust Patterns Over a Water Surface (“Cat's Paws”)
Moving Gust Patterns Water Surface
font style='font-size:12px;'>
2009/4/2
We report on observations of near-surface Velocity, temperature, stress, buoyancy, and surface wave fluctuations, including successive short-time averages of coherences, phases, autospectra, and proba...

Internal Solitary Waves Moving Two-Dimensional Topography
font style='font-size:12px;'>
2009/2/23
The propagation of long internal waves over two-dimensional topography is discussed. A two-dimensional version of the Korteweg-deVries equation is derived with variable coefficients which depend on th...
Continental Shelf Circulation Induced by a Moving, Localized Wind Stress
Continental Shelf Circulation Moving Wind Stress
font style='font-size:12px;'>
2009/2/9
A linear, two-dimensional model of a rotating, stratified fluid is constructed to investigate the circulation induced by a moving, localized line of surface stress. This model is used to analyze the e...
Internal Wave Wake of a Moving Storm. Part I. Scales, Energy Budget and Observations
Internal Wave Moving Storm
font style='font-size:12px;'>
2009/2/5
The ocean's baroclinic response to a steadily moving storm is analyzed using a numerical model for an inviscid, multi-layered fluid. This first part of a two-part study gives a detailed account of the...

font style='font-size:12px;'>
2009/1/19
This paper has two purposes: One is to present a new and efficient multilevel numerical model for calculating the response of the ocean to a moving storm; the second is to show how, on a time scale of...

font style='font-size:12px;'>
2008/12/15
The upper ocean's response to three hurricanes [Norbert (1984), Josephine (1984) and Gloria (1985)] is examined using field observations and a numerical ocean model. Our goal is to describe the physic...
