Bryan (1953) lists about 400 atolls. The full article is available through http://www.botany.hawaii.edu/faculty/duffy/arb/019-23/v019-23.pdf. This is not a definitive list as the definition of an atoll is still the subject of discussion discussion. Bryan, E.H., 1953. Check list of atolls. Atoll Res. Bull., 19: 1-38.
Excessive nutrients in the water can lead to algal overgrowth, which can smother coral and disrupt their ability to photosynthesize. This can weaken the coral and make them more susceptible to disease. Additionally, increased nutrient levels can also lead to ocean acidification, further stressing the coral.
good! high biodiversity means there are many different species which all can interact and make a good ecosystem.
Coral reefs are made up of many things. The coral itself produces calcium carbonate which gives structure to the reef. However there is also an algae which produces limestone at the edges of the reef to strengthen it.
Coral typically lives in shallow, tropical waters in areas known as coral reefs. These reefs are found in various oceans around the world, particularly in the Caribbean Sea, the Red Sea, the Great Barrier Reef in Australia, and the Coral Triangle in Southeast Asia.
Tuvalu consists of nine islands, six of which are atolls and three of which are coral reefs.
The Maldives are approximately 1,190 coral islands. Grouped in a double chain of 26 atolls, they are spread over roughly 90,000 square kilometres.
True. :p
The Marshall Islands are made up of 34 islands. Specifically, they consist of 29 coral atolls (which encircle a lagoon) and 5 coral islands (without a lagoon).

Just the one island.
Yes, where coral reefs are found along the edges of continents; Australia's Great Barrier Reef and Florida USA are two examples. However, many are found around volcanic islands or their remains(atolls).
Tuvalu is made up of nine islands, eight of which are inhabited. Tuvalu, means "eight standing together".
No, not too many people have heard of Tuvalu.

The U.S. used the pacific atolls because they were isolated from large population centers and because the Marshal Islands (where many of these atolls were) were entirely under U.S. control after WW2, so could freely involuntarily evacuate indigenous populations of the atolls that testing was planned on. The USSR did all of their testing inland for security reasons (they also did not have control over any atolls). The British did much of their testing inland on Australia and some in the pacific on Christmas island. The French did their testing in the Sahara desert. The Chinese did all of their testing inland for security reasons. etc.
