temperate glacier
Quick Summary
A temperate glacier is defined as a glacier that is at its melting temperature throughout its mass. While surface freezing occurs in winter, the ice itself remains at the melting point. These glaciers are also known as isothermal glaciers.12
Temperate glaciers move through two primary processes: internal deformation and basal sliding. Basal sliding is particularly significant in temperate glaciers, allowing them to erode their beds effectively and shape the landscape. They act as reservoirs, storing precipitation in both liquid and solid forms and releasing it later. The runoff from these glaciers typically peaks in late July or early August, influenced by factors like solar radiation and the changing reflectivity (albedo) of the glacier's surface. Glacier streams are often characterized by high sediment concentrations, including a fine-grained material known as rock flour.23
