Fig. 2From: Anthropogenic modifications to a barrier island influence Bonnethead (Sphyrna tiburo) movements in the northern Gulf of MexicoMap of the acoustic array used in this study to track five individuals before and after the closure of Katrina Cut. The CAAMP array (n = 35) is represented by blue circles and the SAIC array (n = 38) is represented by green circles. Bonnetheads tagged and released in 2010 (n = 4) are represented by black “x” and Bonnetheads tagged and released in 2011 (n = 1) are represented by red “x”. The symbols representing the CAAMP and SAIC acoustic arrays are scaled to the mean detection range for those receiver types. The upper right panel is a zoomed in view of Katrina Cut with mean detection range for the CAAMP array in light blue and in light green for the SAIC array. The rock-rubble berm is denoted with a string of bold “x” and the receivers which detected Bonnetheads at Katrina Cut (CAAMP receivers in blue) are denoted with an asterisk Back to article page
