Adelie and Chinstrap penguins were fitted with both GPS loggers and time-depth recorder (TDR) tags for between two and fourteen days in order to log their three-dimensional foraging trips. Tags were deployed between December and February of 2011/12, 2013/14 and 2015/16 with a total of 36 Adelie penguin GPS tracks, 37 Adelie penguinTDR tracks, 52 Chinstrap penguin GPS tracks and 48 Chinstrap penguin TDR tracks. : The birds were fitted with Fastloc2 GPS loggers (Sirtrack, Havelock, New Zealand) paired with CEFAS G5 TDRs (CEFAS Technology Ltd, Lowestoft, UK) whose clocks were synchronised in other years. Dive statistics from the TDR tracks were extracted using the R package diveMove (Luque, 2016 - diveMove: Dive Analysis and Calibration. R package version 1.4.1. https://cran.r-project.org/package=diveMove). The filter method of zero offset correction within diveMove (Luque & Fried, 2011 PLOS ONE, 6(1), e15850) was used to define the sea-surface and a depth threshold of 5m was used to exclude any non-foraging dive events (Kokubun, Takahashi, Mori, Watanabe, & Shin, 2010 doi:10.1007/s00227-009-1364-1).
