In recent years there have been discovered, in the Central Arctic Ocean, some very curious ice-formations, known as ice-island. These islands are sharply distinct both from the old ice-fields of the Central Arctic regions and from the icebergs carved by the glaciers which descend into the Arctic Basin. The thickness of the Arctic ice fields (including the hummocks) usually does not exceed 3-5 meters, while the horizontal dimensions both in summer and particularly in winter may be very great (some tens of kilometers). Most of the East Greenland icebergs which have been surveyed had heights of about 70 m and lengths around 1 km. Thus the ratio of vertical to horizontal size is extremely small in ice fields, and in icebergs comparatively large. Ice islands occupy, in this respect, an intermediate position.
