Grain-Size Data from Upper Florida Keys: Crocker Reef, FL

Sediment samples were collected from undisturbed sections of the seafloor around Crocker Reef, Florida which is a senile, degrading barrier reef located in the northern portion of the Florida Reef Tract (Figure 1). Samples were collected from November 2017 to April 2019. The sediment sample locations were near instruments deployed during the same period to record time series of ocean currents, waves, turbidity, and pressure. All sediment samples were analyzed using a laser diffraction Coulter LS13 320 particle-size analyzer and sieve analysis to measure the grain size distribution of the sediments.
