I have included a map of the island so that you can see where I will be during the coral reef study. Earthwatch volunteers having been coming to this island to study coral reefs since 1992.  They have been collecting information about coral populations, erosion and water quality.  I asked you a question in the previous post about why this island is so important to our history.  In 1492, Christopher Columbus made his first landfall in the New World at San Salvador.  At the time, the island was inhabited by Lucayans, a native population which lived by fishing and agriculture.  You can see his exploration of the island from the map.
