MOESM1 of A dawn peak in the occurrence of ‘knifing behaviour’ in blue sharks

Additional file 1: Figure S1. Complete tracks of three blue sharks satellite tagged with SPOT tags off southern Ireland (closed star is approximate tagging location for all sharks). Figure S2. The frequency distribution for the number of knifing events detected through the Argos satellite system per satellite pass. Figure S3. a) The mean depth of Shark B for every 10 s of a 24 h clock (averaged over the entire tracking period of 70 days) (data from recovered PSAT). b) and c) are examples of depth versus time traces for two randomly chosen days (20/10/2012 and 01/11/2012). Figure S4. Hourly binned satellite passes for a period when an individual was resident in the Celtic sea (left panel) and the distribution of knifing events from the Shark D at this time (right panel). Figure S5. Distribution of counts of ‘time of last transmissions’ from a SPOT tag (Shark D) during July 2014. Figure S6. Temperature depth plot for Shark B (from recovered PSAT) showing that there was very little difference in the mean temperatures experienced by this shark during night and day (
