Map of the study area showing its location and the coastline from Pinellas County to Collier County, Florida, USA. Dashed lines show the extension of the county boundaries offshore, solid lines represent the boundaries for equidistant (61.4 km) segments along the coast (represented by solid black line). Circles represent the location of available K. brevis samples within 3 miles of the coast, from October 2004 to February 2007. These are coded dark or light to distinguish samples in adjacent equidistant segments. Inset shows the location of lifeguard beach stations.
