Gravity currents and internal waves in a stratified fluid
(Cambridge University Press, 2008-11-14)
A steady theory is presented for gravity currents propagating with constant speed into a stratified fluid with a general density profile. Solution curves for front speed versus height have an energy-conserving upper bound ...
Salinity and the global water cycle

Numerical study of circulation on the inner Amazon Shelf
We studied the circulation on the coastal domain of the Amazon Shelf by applying the hydrodynamic module of the Estuarine and Coastal Ocean Model and Sediment Transport - ECOMSED. The first barotropic experiment aimed ...
Surprising return of deep convection to the subpolar North Atlantic Ocean in winter 2007–2008
The process of open-ocean convection in the subpolar North Atlantic Ocean forms a dense water mass that impacts the meridional overturning circulation and heat flux, and sequesters atmospheric carbon. In recent years the ...
Lateral organic carbon supply to the deep Canada Basin
(American Geophysical Union, 2008-06-12)
Understanding the processes driving the carbon cycle in the Arctic Ocean is important for assessing the impacts of the predicted rapid and amplified climate change in this region. We analyzed settling particle samples ...
Propagation of a finite-amplitude potential vorticity front along the wall of a stratified fluid
(Cambridge University Press, 2002-10-10)
A similarity solution to the long-wave shallow-water equations is obtained for a density current (reduced gravity = g[prime prime or minute], Coriolis parameter = f) propagating alongshore (y = 0). The potential vorticity ...
Endowments and new institutions for long-term observations
(Oceanography Society, 2007-12)
An ever-increasing volume of publications on the changing ocean environment underscores the requirement for long-term observations to understand and predict ocean and climate change. Such observations must be ...
Shear instability and coherent structures in shallow flow adjacent to a porous layer
(Cambridge University Press, 2007-11-23)
Results are presented from an experimental study of shallow flow in a channel partially obstructed by an array of circular cylinders. The cylinder array is a model for emergent vegetation in an open channel, but also ...
Formation of intrathermocline eddies at ocean fronts by wind-driven destruction of potential vorticity
A mechanism for the generation of intrathermocline eddies (ITEs) at wind-forced fronts is examined using a high resolution numerical simulation. Favorable conditions for ITE formation result at fronts forced by “down-front” ...
