Leatherback turtles satellite-tagged in European waters (2008, background): “1) after 10 November 2005, when normal functioning of its SRDL was impaired (Hays et al. 2001 have shown LC A locations to be comparable with LC 1 locations).”
Important areas at sea for adult loggerhead sea turtles in the Mediterranean Sea: satellite tracking corroborates findings from potentially biased sources (2008, background): “According to Argos and conWrmed by Hays et al. (2001a) , the location errors follow a normal distribution with their standard deviations being less than 1 km for the three most accurate location classes (LCs 3, 2 and 1 in decreasing accuracy).”
Methods for estimating long-distance dispersal (2003, background): “Uncertainties involved with the accuracy of spatial location recorded in such systems (Hays et al. 2001), can be neglected if the movement occurs over such a large spatial scale, but can be consequential if an animal is moving slowly or has a restricted range.”
A novel method for identifying behavioural changes in animal movement data. (2009, methodology): “ARGOS data is reported with location classes (3, 2, 1, 0, A and B) associated with spatial errors varying from 100 m to several kilometres (Hays et al. 2001; Vincent et al. 2002; CLS Argos 2008).”
Using a Remote Technology in Conservation: Satellite Tracking White‐Naped Cranes in Russia and Asia (2004, background): “…and terrestrial environments (e.g., hawksbill turtles [Eretmochelys imbricata], Horrocks et al. 2001; minke whales [Balaenoptera acutorostrata], Heide-Jorgensen et al. 2001; South American sea lions [Otaria flavescens], Campagna et al. 2001; Wandering Albatrosses [Diomedea exulans], Shaffer et…”
Migration of hawksbill turtles Eretmochelys imbricata from Tortuguero, Costa Rica (2005, methodology): “Meylan (1999a) reported on hawksbill nesting at Tortuguero from 1972 to 1998 but the method for deriving annual nest estimates is unclear.”
Moderating Argos location errors in animal tracking data (2012, background): “2), as has been found in previous studies (Keating, Brewster &Key 1991; Hays et al. 2001; Vincent et al. 2002; Costa et al. 2010; Witt et al. 2010) and reported by CLS (2011).”
Satellite tracking of sea turtles: Where have we been and where do we go next? (2008, background): “…UK (Ascension) 15 0 0 0 15 Åkesson et al. (2001) C Atlantic UK (Ascension) 0 2 0 0 2 Hays et al.

Novel GPS tracking of sea turtles as a tool for conservation management (2007, methodology): “Despite this, variable accuracies and infrequent intervals between fixes (Hays et al., 2001; Hulbert and French, 2001) limit their application at finer spatial resolutions, and when quantifying movement patterns in relation to biophysical parameters at small scales (Wilson et al., 2002; Bradshaw et…”
Assessing accuracy and utility of satellite-tracking data using Argos-linked Fastloc-GPS (2010, background): “Second, in general we confirm the typical accuracy of LC A > LC B > LC 0 as has been described previously (Hays et al. 2001).”
Satellite tracking highlights the need for international cooperation in marine turtle management (2006, methodology): “The most accurate positions (LC 3, 2, 1, A; cf. Hays et al. 2001) and biologically realistic speeds (<5 km h–1; cf. Luschi et al. 1998) were used to reconstruct routes and calculate distances traveled, although for loggerheads during migration we also included LC B subject to a speed filter in…”
Migration routes and foraging behaviour of olive ridley turtles Lepidochelys olivacea in northern Australia (2007, background): “Field tests showed that these estimates of accuracy were close to real errors from known locations (Hays et al. 2001).”
Satellite tracking reveals a dichotomy in migration strategies among juvenile loggerhead turtles in the Northwest Atlantic (2009, methodology): “The eVects of location error bias were also minimized when examining large-scale migratory tracks or habitat use (Hays et al. 2001).”
Effect of environmental variability on habitat selection, diet, provisioning behaviour and chick growth in yellow-nosed albatrosses (2005, background): “This difference may bias the comparison of movement rates between the 2 years (Hays et al. 2001) and, consequently, the calculation of the time spent in each grid cell.”
The accuracy of Fastloc‐GPS locations and implications for animal tracking (2014, methodology): “So, for example, with Argos data we have previously suggested that locations need to be >100 km apart (i.e. 2 days apart if the animals are travelling at 50 km day 1) in order to calculate accurate speeds of travel (Hays et al. 2001).”
Wind field and sex constrain the flight speeds of central‐place foraging albatrosses (2009, methodology): “Second, whereas Hays et al. (2001) defined dsep as the minimum distance required between two locations to ensure that the mean of speeds estimated from a series of pairs of locations lies within 610% of the true mean speed on 95% of occasions, we defined dsep more stringently as the minimum…”
