At Sea...
Tim, Mike, and Jeff don their snorkle gear. |

It Looks like everyone is ready to explore the workings of a "carbonate factory" here at the mouth of Pigeon Creek.

Clint Cowan followed by Dorissa Zemirah, Emily LeVine, Callen Hyland, Ellen Schaal, and Amalia Dobbert. |

Clint Cowan leads the pack as the students look at migrating bedforms and various types of carbonate sediment producing green algae. Here he explains the effects of tidal currents in an estuary as everyone experiences first hand the "mutual exclusivity" of the tides.
San Salvador is surrounded by a beautiful system of living reef. Seen here are Elkhorn Coral (Acrapora Palmata), Fire Coral (Millepora), and some Gorgonids or sea fans. These reefs are home to many living organisms but over the years the percentage of living coral has decreased; it is then replaced by other ocean organisms like green algae.

Discussion time! After a long and harrowing swim Heather, Mike, Emily, and Dorissa try to create a profile of the sea floor in French Bay. |
At Ocean House the class sits down to listen to Clint talk about the spring/neap cycle and the ebb and flood of the tide.
