PhD student, Mrs. Deborah Robertson, will be hosting a seminar titled "Introduction to the dynamics of geothermal systems in the Eastern Caribbean." It will be held in the Chemistry Seminar Room (CSW) on Friday 13th November, 2009, from 1:30 - 2:30 p.m.

Abstract:Introduction to the dynamics of geothermal systems in the Eastern Caribbean 

The Eastern Caribbean is one of the most volcanically active regions in the world. One of the main consequences of this activity is the occurrence of geothermal systems in most of the volcanic islands in the region. These systems result from the interaction of cool meteoric waters with underground, magmatic heated rocks. The existence of geothermal systems is often seen by the presence of a wide variety of surface expressions such as volcanic lakes, hot springs and fumaroles. Such surface expressions are perceived as tourist attractions without due consideration to the potential hazards they pose. In addition, new interest has been shown in the use of regional geothermal systems as energy sources. Despite the obvious tourist and energy potential and hidden hazards, the dynamics controlling these systems are poorly understood. Crucial questions remain unanswered - What governs the lifetime of a geothermal system? What is the response of a geothermal system to increased volcanic/magmatic activity?  

This presentation offers a brief introduction to geothermal systems in the region and will present a multi-tiered approach to better understanding their dynamics.
