Tidewater and freshwater glaciers are formed on land but terminate in bodies of water. They often calve to produce floating chunks of glacier ice known as icebergs. In these water-terminating glaciers, calving often accounts for the majority of the glacier's ablation (ice loss).
Tidewater glaciers can flow directly into the ocean in an open coast locations; they also can discharge into steep-walled fjords.
In temperate latitudes, water-terminating glaciers can be among the fastest-flowing in the world. Their high speeds endow them with a high capacity for sculpting and carving the landscape.
