Raw data of Thalassia testudinum mediation of sediment resuspension and settling using traps and plates in a subtropical estuary, Estero Bay, Florida, USA, October 2014 - August 2015

Seagrasses are highly productive and diverse ecosystems which provide many ecological services to organisms. Seagrass canopies create a hydrodynamically low-energy environment which can increase sediment deposition and reduce resuspension, thus enhancing habitat stability. Direct measurements of sediment deposition usually employ cylindrical traps, but results from this method have been debated. Flat sediment plates are an alternative method that minimize the problems of cylindrical traps. Plate traps were used in conjunction with cylindrical traps to measure sediment deposition in a seagrass bed and nearby barren site in Estero Bay, a subtropical estuary in southwest Florida, USA. Sediment plates and cylindrical plates were deployed every 2-3 months in a Thalassia testudinum dominant seagrass bed and nearby barren site to examine seasonal differences in sediment deposition and differences between the vegetated site and the barren site. The data from the plate traps reproduced the reduction of resuspension in the seagrass bed compared to the barren site found in other studies. This result was supported by measurements of reduced near-bed velocity and shear stress in the seagrass meadow. Plate traps had more consistent results than cylindrical traps. Differences between the barren and vegetated sites from the cylindrical traps were noisy.
