Islands play a critical role in focusing and shaping the filling of accommodation at the carbonate platform and EOD scale by influencing the local environment and exerting a clear control over distribution of potential reservoir and nonreservoir. Although islands are aerially restricted within the Joulters ooid sand body, there are profound implications of syndepositional island development including new facies, topography, meteoric diagenesis, and resultant localized heterogeneity. South Joulter Cay (SJC) provides one scenario for island growth highlighting complexity, illustrating important changes in sediment dynamics during sand body development, and suggesting an important control by periods of intense storms.
