The continental shelf averages 150 km in width, with depths of less than 70 m within two km of the shore. Several offshore banks extend to the edge of the steep continental slope that rapidly reaches depths of over 3000 m. The region is covered in ice seven to ten months of the year. The fjords , bays and a narrow coastal zone are bound in landfast ice , while pack ice extends 150-225 km offshore. The tidal range varies from 3 m in the north to 1 m in the south.
Icebergs are abundant and occur year-round.
On the seventh, He sat back, threw rocks at it and created Labrador. Although an accurate description of this rather barren and rocky 20,000 km coast , it does not do justice to its sheer beauty. Strongly influenced by glacial erosion , the shoreline is complex with about 4000 coastal islands and many bays and inlets slashing inland for several kilometres. A precipitous coast ranging in height from 200-1000 m is broken by spectacular fjords and deeply incised valleys. Some 90 species of Arctic and subarctic marine and anadromous fish occur in the region, with important Atlantic cod , Atlantic salmon, Arctic charr and capelin spawning grounds.
