Definition
Ice shelf.Part of anice sheetthat floats on the ocean while remaining attached to grounded ice.
General characteristics
Ice shelves form at the margins of anice sheet, where the ice becomes thin enough to float free of a bed that lies below sea level. Ice shelf-like features also form in the interior of ice sheets where the ice floats on subglacial lakes. Most of the ice shelves that currently exist on Earth are found inAntarctica. In particular, ice shelves almost completely surround themarine ice sheetof West Antarctica. The larger ice shelves are fed by multiple glaciers, the outflows from which coalesce to form a distinct glaciological feature, but the smaller ones are generally the floating termini of singletidewater glaciers. Although any ice that exists between the grounding line and the calving front of a tidewater glacier is formally an ice shelf, these features are often not accorded an identity distinct from their parent glaciers.
Ice shelves range in thickness...
