Just a short entry tonight because it's late, I'm beat, I get up early tomorrow, and have a quiz later in the day. Today's activities (a snorkel and reef walk) were hosted by CoralWatch, a citizen science group whose purpose is to train normal people how to collect basic data about coral reefs that scientists can use to evaluate reef health. This is useful because there aren't anywhere near enough scientists to study every reef, the downside being that the data quality from relatively untrained civilians often isn't that good. Nevertheless, it gets people interested and involved.

Probably the highlight of the day was during the reef walk when our CoralWatch guide plunged his hand into the water and pulled out a small epauletted shark to show to us.
