The Tasman Glacier is one of many freshwater-terminating glaciers located in the Aoraki/M.t Cook National Park that has retreated significantly since the mid-20th century. Although there have been several observations made of the glacier since the formation of Tasman Lake and the following rapid retreat, the glacier entered a period of rapid terminus disintegration and retreat since c. AD 2000. The retreat of Tasman Glacier between 2000 and 2008 has occurred in two distinct periods: an initial period of relatively slow retreat prior to 2006, followed by a secondary period of rapid retreat between 2006 and 2008. Terminus full width retreat for the period 2000-2006 occurred at a rate of 54 m a1, accelerating to 144 m a1 during 2006-2008. During the period 2000-2006, the controlling process of ice loss at the terminus was ice berg 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. Currently, the volume of Tasman Lake is 510 x 106 m3. It will increase dramatically in near future as the lake expands into deeper water
