Not only a data base, but a knowledge bank as well, the UN Atlas of the Oceans provides extensive information on the world's oceans and seas, gathered by various national and international agencies, including the United Nations; NOAA; and HDNO, the Russian Head Department of Navigation and Oceanography. Featuring maps, images, statistics, and other factual information gathered on the oceans, the site offers a sea of compelling topics, among them uses of the oceans and waterways, recreation and tourism, transportation and telecommunications, human coastal settlements, and the exploration and exploitation of natural resources. Also contained within the site are a number of stand-alone but interrelated modules about the oceans: how they were formed, how they are changing, and their dynamics. Sure to please curious minds are the site's depth profiles and its presentations on earthquakes, volcanoes, and tsunamis.
