Ice floe

An ice floe (/floʊ/) is a segment of floating ice defined as a flat piece at least 20 metres (66 ft) across at its widest point, and up to more than 10 kilometres (6.2 miles) across. Drift ice is a floating field of sea ice composed of several ice floes. They may cause ice jams on freshwater rivers, and in the open ocean may damage the hulls of ships.
