Sediment properties in shallow waters around Tampa Bay, FL in July 2015

Sediments were collected in conjunction with infauna sampling at three sampling locations around Tampa Bay, FL in 2015 and analyzed for porosity of depth slices of 1 cm increments for the top 5 cm and 2 cm increments for 5-15 cm depth. C and N were measured at the USFSI Stable Isotope Lab, Department of Geology, University of South Florida, Tampa, using a Costech elemental combustion system, and data are given as total N (umol), total C (umol) and C:N ratio. Sediment grain size analysis was done using standard gravitational methods and is presented as % sand, silt, clay, and mud. Samples were collected in shallow water (0.25-1 m depth) in Halodule and Thalassia beds and adjacent bare (unvegetated) sediments.
