Resumen

La altitud de la línea de equilibrio de los glaciares nos indica en qué punto el glaciar está en equilibrio con el clima, en ese punto la cantidad de masa ganada es equivalente a la que se pierde. Es muy común la utilización de la altitud de la línea de equilibrio glaciar como indicador climático, por ello se hace necesario disponer del estado actual de los glaciares, o de su estado durante la época de cuando se quiere reconstruir el clima. Para obtener estos datos es necesario disponer de la superficie, e idealmente, del volumen de los glaciares. Para obtener estas delimitaciones se propone una metodología de trabajo que empieza por realización de esquemas geomorfológicos con el objetivo de poder deducir los límites alcanzados por el hielo en otras épocas y posteriormente proceder a su reconstrucción y al cálculo de las líneas de equilibrio glaciar. Este estudio presenta el estado del arte de las metodologías y los procedimientos utilizados en las últimas décadas para realizar reconstrucciones glaciares y calcular la altitud de las líneas de equilibrio glaciar.
