A class picture at Poas Volcano in Costa Rica, 1997.
This research project seeks to examine the impact that intense tropical storms have on coral reef communities in the Caribbean. Since we will be diving extensively in San Salvador, I have chosen to use this opportunity to utilize the island's recent hurricane events (Bertha & Lili in 1996; Floyd in 1999) to examine coral reef recovery rates on the island. This research will include identification of damaged or recovering coral growths, observation of their relative position given the proximity and bearing of the storm, and an attempt to assess the reef's resilience.
The following text is a synopsis of my research presentation.
A. Brief Synopsis of Recent San Salvador Hurricane History
1. 1996; Hurricane Bertha, Hurricane Lili
2. 1999; Hurricane Floyd
B. Hurricane Formation Process (if applicable)
1. Pleistocene era Disturbance
a. Coral core drilling
b. Storm surge sedimentation
c. Stalagmite Evidence
3. Modern Ecological Relevance
a. Differences between ancient & modern recovery rates
b. Possible indicator of the effects that global climate change may have on hurricane intensity
II. Hurricane Effects on Coral Reef Communities.
A. Direct Effects
1. What causes damage? How?
a. sedimentation, windswept waves, pre-storm surge, debris upheaval (aquatic,anthropogenic), etc.
2. What types of corals are damaged?
3. Photographic examples
B. Indirect Effects
1. Biotic Reef Inhabitants
2. Extraneous effects (chronic anthropogenic effects, disease, extirpation, extinction,diminished water quality, etc).
III. Recovery Process/Adapations
A. Recovery Rates of Various Coral Species
1. Natural recovery rate? or affected by extraneous inputs?
2. Growth Rate of Selected Species
1. Resilient Features
IV. Research Design
