Topographically-driven fresh groundwater flow in offshore carbonate platforms.

Descrizione del progetto

Nuovi modelli potrebbero gettare nuova luce sulla geologia delle piattaforme carbonatiche

Le piattaforme carbonatiche sono strutture 3D geologicamente complesse che si prestano a diventare degli ottimi serbatoi di risorse d’acqua dolce. Tuttavia, la maggior parte dei modelli che descrivono la loro idrogeologia sono 2D e si basano su ipotesi semplicistiche riguardo ai processi di flusso e alle caratteristiche geologiche. Il progetto OFF-GROUND, finanziato dall’UE, si propone di costruire modelli 3D geologici e idrogeologici rappresentativi delle acque sotterranee raffreddate offshore nell’altopiano Malta. Lo studio farà nuova luce sulla geometria 3D, la scala e il tasso di circolazione dei fluidi e determinerà in che modo le acque sotterranee meteoriche guidate dalla topografia potrebbero rappresentare una futura fonte di acqua potabile.

Obiettivo

Carbonate platforms are geologically complex 3D structures. Their hydrogeology has been investigated via conceptual models, sand box experiments and numerical models. Most of these models are hypothetical, 2D in nature, and based on simplistic assumptions on flow processes and geological characteristics. Recently, topographically-driven meteoric groundwater has been proposed as a key player in driving fluid circulation in carbonate platforms, both onshore and offshore. This project is dedicated to building representative 3D geological and hydrogeological models of offshore freshened groundwater in the Malta Plateau, to specifically address the following questions: what is the 3D geometry, scale and rate of fluid circulation in carbonate platforms, at present and during sea level lowstands? What are the main controlling factors? What are the key processes driving fluid circulation in carbonate platforms, at present and during sea level lowstands? What is the role played by topographically-driven meteoric groundwater? Addressing these knowledge gaps is important for the future use of offshore freshened groundwater as a source of potable water, and provide insights into diagenetic processes. During this research I will have the possibility to widely expand my geoscience knowledge, from Oil & Gas to Water, too, both during the time I will spend working at University of Malta, as host organization, as well as during my secondment c/o Geomar, in Germany. I will dedicate myself to disseminate the results of my research through specific planned actions, and I expect to mature a CV and a research experience strong enough to allow me to start a new carrier in the academic/research world in the near future, based on my previous experience in the industry and on the new skill I will learn.
