Insular Margins of Iceland

  • Gudmundur Pálmason


Iceland, with an area of about 100,000 km2, straddling the Mid-Atlantic Ridge and the Greenland-Scotland rise, is surrounded by a shelf of shallow depth, mostly 100–300 m, with an area larger than that of Iceland itself (Fig 1). The shelf edge is in some places relatively steep, especially to the southeast and northeast. The bathymetry is more complicated where the crest of the Mid-Atlantic Ridge enters the shelf, to the southwest and to the north. In some parts of the shelf shallow, wide valleys are found with a relief of 100–150 m, many of them located in front of the main present-day rivers on the shore.
