Description:

Abstract:

Two areas of the west Florida shelf seafloor were studied in order to understand the spatial and temporal variations in sedimentary cover; the relationship between sedimentary properties and remotely sensed data; and the relationships of data of different spatial and temporal scales. Analyses of side-scan sonar imagery; sediment samples; and box cores reveal spatial differences in the size; shape; spacing; surficial grain size distribution; and sub-surface sedimentary structures of sand ridges found at 5-8 m water depth compared to sand lenses at 15-18 m water depth. Northwest-southeast trending sand ridges in the nearshore area are an order of magnitude smaller in spatial extent than those in the midshelf. Side-scan backscatter reflects the heterogeneity of the nearshore surface sediments and the homogeneity of the midshelf sediments. Box core peels reveal these surficial sedimentary properties extend to a depth of 25 cm in both study areas.

Purpose:

The purpose of this data layer is to create a digital version of the sedimentary characteristics published by Hafen (2001) for inclusion in the usSEABED data collection.
