NERC EDS UK Polar Data Centre. https://doi.org/10.5285/7045c297-a59d-4801-be4c-a5b95b539358 This study took place from 12 November to 1 December 2015, at the emperor penguin colony at Rothschild Island (-69.5 S, -72.3 W) located on sea ice < 1 km from the eastern coastline of the island in Lazarev Bay. ARGOS telemetry devices were attached to adult emperor penguins en route to, or from, the colony. The last recorded positions were on 26 April 2016 when data collection was terminated; at this date six instruments were still transmitting. PTT devices were deployed as a joint operation between Philip Trathan (British Antarctic Survey), and Barbara Wienecke (Australian Antarctic Division). Catrin Thomas acted as the BAS Field General Assistant. Funding: This work was supported by the UKRI/ BAS ALI-Science project and to the Australian Antarctic Program. Philip Trathan was also supported by WWF (UK) under grant GB095701.

We weighed each penguin to the nearest 0.5 kg using a suspended mechanical scale, and attached either a Wildlife Computers (n = 15) (model SPOT-275) or Sirtrack (n = 18) (Kiwisat K2G 273A rated to over 500 m; 95 g; 78 x 43 x 27 mm) satellite telemetry (ARGOS PTT) device to each individual. The Wildlife Computers tags were programmed to transmit at 60 s frequency, whilst the Kiwisat tags transmitted every 90 s. We attached devices on the dorsal mid-back of each penguin using Loctite 401 quick-setting glue and two plastic cold-resistant cable ties, which we sealed with glue. After release, we observed each penguin for as long as possible but did not detect any unusual behaviour. Data from the Sirtrack devices are also available from the AAD. All PTT location data were analysed using R version 3.5.1 (R Core Team, 2018). Initially, fixes that would have required an average cruising speed of more than 2.2 m s-1 were removed using speedfilter (R package trip v1.6.0). We then used crwMLE (R package crawl v2.2.1) to fit continuous-time correlated random walk models and interpolated tracks at 5-minute intervals using crwPredict. Telemetry data are often incomplete or imprecise; as such these models allow for uncertainty in location. Location data from the 5-minute interpolated tracks were used for all subsequent analyses. The tracking data cover the period from deployment until the time when the penguin's annual moult was underway, although some tags ceased transmitting earlier.
