1. Due to natural fluctuations, ambiguities surrounding ice shelves, and mapping conventions for vertical datums, exact values for land and ocean coverage are not meaningful. Based on data from the Vector Map and Global Landcover datasets, extreme values for coverage of lakes and streams are 0.6% and 1.0% of the earth’s surface. Note that the ice shields of Antarctica and Greenland are counted as land, even though much of the rock which supports them lies below sea level.
