Scaling analysis of single‐plume convection from a hydrothermal source [PDF]
Journal of Geophysical Research: Oceans, 2008 The characteristics of a convective single plume developing from a hydrothermal lake source of radius R have been investigated. The study was motivated by the aim of estimating velocity and buoyancy scaling laws obtained from numerical models of convection from isolated sources of finite extent.

Inversion approach for thermal data from a convecting hydrothermal system [PDF]
Journal of Geodynamics, 1985 Hydrothermal systems are often studied by collecting thermal gradient data and temperature depth curves. These data contain important information about the flow field, the evolution of the hydrothermal system, and the location and nature of the ultimate heat sources.

Advanced Functional Materials, EarlyView.ABSTRACT Breathable membranes that reject chemical warfare agents (CWAs) are required for next‐generation protective apparel. A dual‐function graphene oxide (GO)‐polyamine architecture is introduced that addresses the long‐standing tradeoff between vapor transmission and CWA selectivity.

Hydrothermal waves and corotating rolls in laterally heated convection in simple liquids [PDF]
Journal of Non-Equilibrium Thermodynamics, 2004 The stability of a liquid layer with an undeformable interface open to the atmo- sphere, subjected to a horizontal temperature gradient, is theoretically analysed. Buoyancy and surface tension forces give rise to a basic flow for any temperature dif- ference applied on the system.

Problems with imaging cellular hydrothermal convection in oceanic crust
Geophysical Research Letters, 1996 Heat‐flow variations are commonly used to infer the existence of hydrothermal convection in young oceanic crust and, in special cases, the geometry and vigor of convection. In a small area on the eastern flank of the Juan de Fuca Ridge where the sea floor and seismic basement relief are only about 10 m, a coherent pattern of heat‐flow variation having ...
