Abstract:
"Columbus Park is a turbid lagoonal reef site in Discovery Bay, Jamaica, whre bauxite is loaded onto ships for transport. In Columbus Park, growth of Siderastrea siderea colonies (radial growth rate=2.0+/- 1.7 mm/yr, n=3) and Acropora cervicornis colonies (linear extension rate=2.51+/- 2.2 cm/yr; n=3) were significantly (p=0.0005 for both) lower than at Dairy Bull (Siderastrea siderea radial growth rate= 6.6 +/- 2.2 cm/yr; n=3 and Acropora cervicornis linear extension rate = 10.95 +/- 2.72 cm/yr; n=3) on the Discovery Bay fore-reef. Zooanthellae from Acropora cervicornis samples (n=5) in Columbus Park were all clade A, while zooxanthellae clades A, B, and C were found in Acropora cervicornis samples (n=5) at Dairy Bull. The implication of chronic sedimentation and acute extreme events on the coral reefs of Discovery Bay is discussed."
