|MY NASA DATA: Coral Bleaching in the Caribbean (Lesson 23)|
In this lesson, students collect sea surface temperature (SST) data from the MY NASA DATA Live Access Server (LAS), create time-series line plots, and use the plots to study a major coral bleaching event. Corals feed on algae that thrive in the sunlit water surrounding a reef. However, when water temperatures get too warm, the algae food source dies and corals turn a whitish color. Through scientific observation, it has been determined that coral bleaching may occur when SST exceeds 30C or 86F for a week or longer. During late 2005, a major coral bleaching event, selected for study in this lesson, occurred as a result of these conditions in the Caribbean Sea. The lesson provides detailed procedure, related links, sample graphs, follow-up questions, extensions, and teacher notes.
