Two-dimensional magnetohydrodynamic turbulence in the small magnetic Prandtl number limit
(2012-07-01) - Journal article,
In this paper we introduce a new method for computations of two-dimensional magnetohydrodynamic (MHD) turbulence at low magnetic Prandtl number $\Pra=\nu/\eta$. When $\Pra \ll 1$, the magnetic field dissipates at a scale ...
Shallow-water vortex equilibria and their stability
(2011-01-01) - Journal article,
We first describe the equilibrium form and stability of steadily-rotating simply-connected vortex patches in the single-layer quasi-geostrophic model of geophysical fluid dynamics. This model, valid for rotating shallow-water ...
Simply-connected vortex-patch shallow-water quasi-equilibria
(2014-03-05) - Journal article,
We examine the form, properties, stability and evolution of simply-connected vortex-patch relative quasi-equilibria in the single-layer ƒ-plane shallow-water model of geophysical fluid dynamics. We examine the effects of ...
Bayesian methods for hierarchical distance sampling models
(2014-06-01) - Journal article,
The few distance sampling studies that use Bayesian methods typically consider only line transect sampling with a half-normal detection function. We present a Bayesian approach to analyse distance sampling data applicable ...
The influence of a fluid-porous interface on solar pond stability
(2013-02) - Journal article,
The linear instability of the gradient zone of a solar pond containing a fluidporous interface is investigated. It is found that the gradient zone can retain the same stability for lower values of the solute Rayleigh number ...
Quasi-geostrophic shallow-water doubly-connected vortex equilibria and their stability
(2013-05) - Journal article,
We examine the form, properties, stability and evolution of doubly-connected (two-vortex) relative equilibria in the single-layer ƒ-plane quasi-geostrophic shallow-water model of geophysical fluid dynamics. Three parameters ...
A new approach to estimate fecundity rate from inter-birth intervals
(2017-04) - Journal article,
Accurate estimates of fecundity rate are key to population assessments and effectively direct conservation efforts. We present a new approach to estimate fecundity rate based on the probability of a female giving birth, ...
50-Year Anniversary of Papers by Cormack, Jolly and Seber

Capture-recapture abundance estimation using a semi-complete data likelihood approach
(2016-03) - Journal article,
Capture-recapture data are often collected when abundance estimation is of interest. In the presence of unobserved individual heterogeneity, specified on a continuous scale for the capture probabilities, the likelihood is ...
Existence, stability and formation of baroclinic triples in quasi-geostrophic flows
(2015-12) - Journal article,
Hetons are baroclinic vortices able to transport tracers or species, and which have been observed at sea. This paper studies the offset collision of two identical hetons, often resulting in the formation of a baroclinic ...
