Sierra Fortune The transportation of sediment is an important aspect in understanding the complex processes that form our coasts. The geology of Florida’s coastline is particularly interesting. The mainland of Florida is primarily dominated by silica-based quartz sands. However, the Florida Keys are dominated by carbonate-based sands composed of either algae and coral fragments or ooids. Since Florida’s underlying geology is composed of limestone, then it seems that the sands found coasts should be carbonate-based. Since the sands are not, in fact, carbonate-based, this leaves us with two major questions: where is this sediment coming from, and why does it stop at the Keys. In order to answer these

Unformatted text preview: questions, data was collected along both sides of the Florida coast from north to south. This data included sediment sample from the beaches, as well as sediment cores. The data from the sediment samples was collected to help determine the composition of the sediments present, with emphasis on heavy metal content, quartz content and possible traces of carbonate sands. This information is used to help determine the source of the material. The core samples were used to help determine the chronology of the sediments, which is useful in identifying the distances in which the sediments have traveled....
