Abstract
El objetivo final de esta tesis doctoral es analizar el balance de masa de los glaciares Hurd y Johnsons, en isla Livingston, una isla glaciada que forma parte del archipiélago de la Shetland del Sur, situado al noroeste de la península Antártica. Un elemento esencial de esta investigación es analizar la evolución del balance de masa de estos glaciares en el contexto de las variaciones climáticas regionales. En este sentido, el estudiar dos glaciares de distinta morfología (Hurd, terminado en tierra, y Johnsons, terminado en mar) confiere un interés especial a esta tesis, ya que la respuesta dinámica de estos glaciares a las variaciones climáticas, y sus cambios de balance de masa asociados, es distinta. Además, se trata de dos glaciares representativos de un gran número de glaciares de ambos tipos presentes en esta región, por lo que su estudio tiene un interés no sólo local, sino regional..
The final aim of this PhD thesis is to analyse the mass balance of Hurd and Johnsons glaciers, Livingston Island, a glacierized island that is part of the South Shetland Islands archipelago, located to the northwest of the Antarctic Peninsula. A key element of this research is investigating the evolution of the mass balance of these glaciers in the context of the regional climate variations. In this sense, studying two glaciers with distinct morphology (Hurd, land-terminating, and Johnsons, sea-terminating) confers to this thesis a special interest, because the dynamic response of these glaciers to climate variations, and their associated mass balance changes, is different. Moreover, these glaciers are representative of many glaciers of both types located in this region. Hence, their study has not only local, but also regional interest...
