Advances in Marine Ecosystem Dynamics from US GLOBEC: The Horizontal-Advection Bottom-up Forcing Paradigm
Global ocean ecosystem dynamics ecosystem climate Marine ecosystems
2015/7/16
A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale climate forcing under the assumption that bottom-up forci...
The effect of groundwater advection on salinity in pore waters of permeable sediments
groundwater advection salinity in pore waters permeable sediments
2014/4/18
Measurements of the upward advection and pore-water profiles of salinitywere made at three coastal settings(the Venice Lagoon, Italy; Jamaica Bay, New York; and Mattituck, New York). Coincident measur...
The Mediterranean Outflow—A Simple Advection-Diffusion Model
Mediterranean Outflow Advection-Diffusion Model
2009/3/24
The influence of the subtropical gyre on the spread of Mediterranean Water in the Atlantic is discussed in terms of a simple horizontal advection-diffusion model. The northern, southern and western bo...
Effects of Horizontal Advection on Upper Ocean Mixing：A Case of Frontogenesis
Horizontal Advection Upper Ocean Mixing Frontogenesis
2009/2/10
The wind stress on the ocean surface induces horizontal advection and vertical mixing, two mechanisms which are capable of changing the surface water density. Advection and mixing can enhance or parti...
Self-Advection of Density Perturbations on a Sloping Continental Shelf
Density Perturbations Self-Advection Sloping Continental Shelf
2009/2/5
Bottom water movement on the continental shelf is modeled by the nonlinear interaction between long-shore bottom geostrophic flow and the density field. Bottom geostrophic velocity, subject to linear ...

Submesoscale Thermal Features Alboran Sea Gyre
2009/1/19
NOAA-7 infrared and Nimbus-7 multi-spectral visible imagery of the Alboran Sea collected as part of the “Donde Va?” experiment during the period 6–20 October, show the advection of submesoscale cold-w...
Extraction of Mixed Layer Advection Velocities, Diffusion Coefficients, Feedback Factors and Atmospheric Forcing Parameters from the Statistical Analysis of North Pacific SST Anomaly Fields
sea surface temperature Mixed Layer Advection Velocities Diffusion Coefficients
2009/1/9
The statistical properties of observed North Pacific sea surface temperature (SST) anomalies are simulated by a simple mixed layer advection and diffusion model with stabilizing feedback and local sto...

Coastal Frontal Zone field experiment Momentum Buoyancy numerical modeling
2008/12/30
We report a study of a coastal frontal zone of the southeastern United States based on a field experiment and numerical modeling. The study was conducted in the spring of 1985 during weak to moderate ...
The Vertical Advection of Momentum in Bryan-Cox-Semtner Ocean General Circulation Models
Vertical Advection Bryan-Cox-Semtner
2008/12/12
This paper is concerned with the way that the Bryan-Cox-Semtner type ocean general circulation models represent the vertical advection of momentum, particularly at horizontal scales which are only sli...
