On the convective overstability in protoplanetary discs
(Oxford University PressMonthly Notices of the Royal Astronomical Society, 2016-01-21)This paper explores the driving of low-level hydrodynamical activity in protoplanetary-disc dead zones. A small adverse radial entropy gradient, ordinarily stabilized by rotation, excites oscillatory convection (‘convective ...

Sea-ice thermodynamics and brine drainage
(Royal Society PublishingPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015-07-13)Significant changes in the state of the Arctic ice cover are occurring. As the summertime extent of sea ice diminishes, the Arctic is increasingly characterized by first-year rather than multi-year ice. It is during the ...

The fluxes and behaviour of plumes inferred from measurements of coherent structures within images of the bulk flow
(Taylor & FrancisAtmosphere - Ocean, 2016-06-01)This paper describes how measurements of the movement of identifiable features at the edge of a turbulent plume can be interpreted to determine the properties of the mean flow and consequently, using plume theory, can be ...
