A world map shows that the higher producers of wheat are China, India, and Russia (shaded dark green). The US, Canada, Australia, and Pakistan produce moderate amounts (green). Chile, Turkey, Iran, and Kazakhstan produce less (lighter green). Many countries in Africa are in the lowest, lightest green category.

A world map showing the distribution of continental shelves. The continental shelves extend into the oceans along the margins of the continents.

Extent of the world's continental shelves, which are extensions of continents submerged by the oceans

Continental Shelf

Key areas with prominent continental shelves shaded in dark blue include the eastern and western coasts of North America, particularly around the Gulf of Alaska, Hudson Bay, and the Gulf of Mexico. The coasts of Europe, including the North Sea and the waters around the United Kingdom. The northern coast of Russia and the Arctic Ocean. The coasts of China, Japan, and Southeast Asia. The northern and eastern coasts of Australia. The coasts of South America, especially around the Gulf of California and the southern tip near Chile and Argentina. The western and southern coasts of Africa, particularly around Angola, Namibia, and South Africa.

A map illustrates the distribution of calcium carbonate in modern surface sediments globally, with highest concentration found in the Caribbean, Mediterranean, and South Pacific and lowest concentration dominating the North Pacific, and Southern Ocean.

Percentage of ocean surface comprised of calcium carbonate.

Distribution of Calcium Carbonate in Modern Surface Sediments

The distribution is represented as a percentage by weight. Areas with the least calcium carbonate, ranging from 0 percent to 20 percent, are marked in very light blue and are prevalent in large parts of the Pacific Ocean, particularly around Samoa, the South Pacific, and parts of the Indian Ocean. Light blue regions, representing 20 percent to 40 percent calcium carbonate, cover parts of the North Atlantic Ocean, including areas around Cuba, the western coast of Africa near Senegal and Mauritania, and the southern Indian Ocean near Madagascar. Medium blue areas, indicating 40 percent to 60 percent calcium carbonate, include regions in the North Atlantic Ocean, off the coast of the United Kingdom and France, the Mediterranean Sea, parts of the Arabian Sea, and the South Pacific Ocean. Blue-green regions, with 60 to 80 percent calcium carbonate, are seen in the central Atlantic Ocean, areas around the Caribbean including Cuba and Guatemala, the western coast of Africa near Gabon and Angola, and the Indian Ocean. The highest concentration of calcium carbonate, 80 percent to 100 percent, marked in dark green, is found in regions of the North Atlantic Ocean, around the Bahamas and north of Cuba, parts of the South Atlantic Ocean near the eastern coast of South America, the central Pacific Ocean, and the northern Indian Ocean near Sri Lanka.
