Abstract

In the Aoraki/Mt Cook National Park, the retreat of Tasman Glacier between 2000 and 2008 has occurred in 2 distinct periods : an initial period of relatively slow retreat prior to 2006, followed by a secondary period of rapid retreat between 2006 and 2008. During the period 2000–2006, the controlling process of ice loss at the terminus was iceberg calving resulting from thermal undercutting. In contrast, the retreat between 2006 and 2008 was probably controlled by buoyancy-driven iceberg calving caused by decreased overburden pressure as a result of supraglacial pond growth. As a result, the surface area of Tasman Lake has increased by 86% over the period 2000–2008, with lake volume increasing by 284% between 1995 and 2008
