� 1998 American Meteorological Society Simulation of DensityDriven Frictional Downslope Flow in ZCoordinate Ocean Models
, 1997
"... An important component of the ocean’s thermohaline circulation is the sinking of dense water from continental shelves to abyssal depths. Such downslope flow is thought to be a consequence of bottom stress retarding the alongslope flow of densitydriven plumes. In this paper the authors explore the p ..."

the potential for explicitly simulating this simple mechanism in zcoordinate models. A series of experiments are performed using a twin densitycoordinate model simulation as a standard of comparison. The adiabatic nature of the experiments and the importance of bottom slope make it more likely that the densitycoordinate
Modeling ice shelf cavities in a zcoordinate ocean general circulation model
 J. Geophys. Res.Ocean
, 2008
"... Abstract. Processes at the ice shelfocean interface and in particular in ice shelf cavities around Antarctica have an observable effect on the solutions of basin scale to global coupled iceocean models. Despite this, these processes are not routinely represented in global ocean and climate models ..."

mate models. It is shown that a new ice shelf cavity model for zcoordinate models can reproduce results from an intercomparison project of earlier approaches with vertical σ or isopycnic coordinates. As a proof of concept, ice shelves are incorporated in a 100 year global integration of a zcoordinate
An embedded bottom boundary layer formulation for zcoordinate ocean models
 J. Ocean Atmos. Tech
, 2000
"... An embedded bottom boundary layer (EBBL) scheme is developed to improve the bottom topographic representation in zcoordinate ocean general circulation models. The EBBL scheme is based on the combined techniques of an embedded topographyfollowing slab (Beckmann and Doscher 1997; Gnanadesikan et al. ..."

Isoneutral Diffusion in a zCoordinate Ocean Model
, 1998
"... This paper considers the requirements that must be satisfied in order to provide a stable and physically based isoneutral tracer diffusion scheme in a zcoordinate ocean model. Two properties are emphasized: 1) downgradient orientation of the diffusive fluxes along the neutral directions and 2) zero ..."

The Dantzig selector: statistical estimation when p is much larger than n
, 2005
"... In many important statistical applications, the number of variables or parameters p is much larger than the number of observations n. Suppose then that we have observations y = Ax + z, where x ∈ R p is a parameter vector of interest, A is a data matrix with possibly far fewer rows than columns, n ≪ ..."

about which coordinates are nonzero, and which were above the noise level. In multivariate regression and from a model selection viewpoint, our result says that it is possible nearly to select the best subset of variables, by solving a very simple convex program, which in fact can easily be recast as a
Spurious Diapycnal Mixing Associated with Advection in a zCoordinate Ocean Model
 MONTHLY WEATHER REVIEW VOLUME
, 1998
"... This paper discusses spurious diapycnal mixing associated with the transport of density in a zcoordinate ocean model. A general method, based on the work of Winters and collaborators, is employed for empirically diagnosing an effective diapycnal diffusivity corresponding to any numerical transport ..."

Tracer conservation with an explicit free surface method for zcoordinate ocean models
 MON. WEA. REV
, 2001
"... This paper details a free surface method using an explicit time stepping scheme for use in zcoordinate ocean models. One key property that makes the method especially suitable for climate simulations is its very stable numerical time stepping scheme, which allows for the use of a long density time ..."

"... Abstract. The carbon cycle is a major forcing component in the global climate system. Modelling studies, aiming to explain recent and past climatic changes and to project future ones, increasingly include the interaction between the physical and biogeochemical systems. Their ocean components are g ..."

are generally zcoordinate models that are conceptually easy to use but that employ a vertical coordinate that is alien to the real ocean structure. Here, we present first results from a newlydeveloped isopycnic carbon cycle model and demonstrate the viability of using an isopycnic physical component
