turtle foraging areas obtained through satellite telemetry from 9 turtles
during the period 2008–2011 (González Carman et al., 2012; Fig. 2).
Animal positions were analyzed with state-space models to identify
locations where the animals were likely engaged in foraging activities
(Breed et al., 2009; Maxwell et al., 2011; see modeling details in
González Carman et al., 2012). Fixed kernel density estimation was
used to construct a map showing foraging areas, created from the
‘foraging’ locations from the state-space model results.
