Накратко на български

Геологията и топлинният поток под леденото покривало на Източна Антарктика разкриват как тектоничните процеси влияят върху земната кора. Тези данни помагат за по-доброто разбиране на топенето на леда, хидрологията под него и промените в глобалното ниво на моретата.

Peering through the East Antarctic Ice Sheet to reveal geology, crustal architecture and tectonic influences on ice sheet dynamics

Antarctica is a pivotal component of the global climatic system however it remains the least known continent on Earth from a geological view point. Geothermal heat flow depends on several geological factors including mantle heat flux, heat production of the crust, and tectonic history. The heat flux underneath the ice in Antarctica is fundamentally important because it influences the basal melting of the ice and thereby defines the boundary condition for ice sheet behaviour, subglacial hydrology, and sea-level change. In addition, the heat flux helps provide an insight into the subglacial geology. However, recent assessments of the large-scale heat flux underneath the Antarctic continent have shown significant differences, and this parameter is very poorly understood. REVEAL aimed to explore the interaction of subglacial geology and ice behaviour across the entire Antarctic continent and it provided an improved knowledge of the geothermal heat flux and its fundamental impact for several scientific communities, including glaciology and the solid Earth sciences. In addition, our potential fields and tectonic models and interpretations enabled us to test several hypotheses regarding the effects of tectonic collision, accretion and rifting on the continent as well as improving understanding of the impact of supercontinental assembly and break up on Antarctica. The REVEAL project has a strong international dimension and it delivered several high-profile publications and dissemination activities. It has also provided unique and timely training and career development opportunities for the Experienced Researcher.

Цел на проекта

Although East Antarctica is regarded as a keystone in the Rodinia and Gondwana supercontinents and is a pivotal component of the global climatic system it remains the least known continent on Earth. With REVEAL we aim to unveil the crustal structure, tectonic architecture and evolution of several major frontier regions in East Antarctica. The project will also address large-scale geological controls on bedrock topography, subglacial hydrology and ice sheet dynamics. Our models and interpretations of potential field data will enable us test several hypotheses regarding the effects of collision, accretion and rifting on East Antarctica. This has significant implications for comprehending the impact of supercontinental assembly and break up on the structure and evolution of East Antarctica. Using state of the art three dimensional modelling, we will obtain an enhanced understanding of intraplate mountain building in the enigmatic Gamburtsev Subglacial Mountains region. This is highly significant, as these mountains were critical for East Antarctic Ice Sheet development. The enhanced knowledge of subglacial geology that will derive from our analyses of the Recovery Frontier and Wilkes Land will facilitate new assessments of the influence of geological boundary conditions on the dynamics and the stability of these potentially more vulnerable marine-based parts of the East Antarctic Ice Sheet. The REVEAL project has a strong international dimension and will deliver several high-profile publications and dissemination activities. It will provide unique and timely training and career development opportunities for the experienced researcher.
