Chetumal Bay lies on the Border between Mexico and Belize. To the east of the bay, Ambergris Cay connects the Belize Barrier Reef to the Yucatan Peninsula. The north of the island is Bacalar Chico Marine Reserve. Here, the barrier reef comes very close to the east side of the island. In 1998, reefs in Belize were hit by two major events that led to heavy coral mortality: El Niño-related coral bleaching and Hurricane Mitch.

The Sudanese coast of the Red Sea is a well-known destination for diving due to clear water and abundance of coral reefs (or shia’ab in Arabic). Reefs are formed primarily from precipitation of calcium carbonate by corals. (In addition to its commonly used meaning, precipitation can also describe how something dissolved in a solution becomes “undissolved” through chemical or biological processes.) Massive reef structures are built over thousands of years of succeeding generations of coral. In the Red Sea, fringing reefs form on shallow shelves of less than 50 meters depth along the coastline. This astronaut photograph illustrates the intricate morphology of the reef system located along the coast between Port Sudan to the northwest and the Tokar River delta to the southeast.
