Satellite imagery can be used to detect variation in abundance of Weddell seals (Leptonychotes weddellii) in Erebus Bay, Antarctica (2011, unknown): “…has advanced such that the use of satellite imagery may now be used to conduct signiWcant research in the Antarctic (Barber-Meyer et al. 2007; Fretwell and Trathan 2009; Fretwell et al. unpublished data), while minimizing the substantial eVorts and impact to the Antarctic environment of…”
Building capacity in biodiversity monitoring at the global scale (2017, background): “Other researchers then refined and expanded the technique to identify new emperor penguin-colony locations (Fretwell and Trathan 2009) and to generate a global, synoptic survey of penguin species from space (Fretwell et al. 2012; Lynch and LaRue 2014).”
The Importance of Krill Predation in the Southern Ocean (2016, background): “Techniques to better estimate the population sizes of some krill predators, particularly surface breeding species such as penguins, are now becoming available with the advent of high 17 resolution satellite imagery (e.g. Fretwell and Trathan 2009, Fretwell et al. 2012).”
A small unmanned aerial system for estimating abundance and size of Antarctic predators (2015, background): “…2011; Lynch et al. 2012; Fretwell et al. 2012; McMahon et al. 2014; Lynch and LaRue 2014) and reveal large-scale spatial distributions of others (Fretwell and Trathan 2009), methodological challenges remain for providing accurate M.

Earth observation satellite sensors for biodiversity monitoring: potentials and bottlenecks (2014, background): “A comprehensive study by Fretwell and Trathan (2009) demonstrated the use of Landsat data for the detection of faecal stains, revealing the location of emperor penguin colonies at 38 sites scattered along the shore of Antarctica.”
Satellite remote sensing for applied ecologists: opportunities and challenges (2014, methodology): “…moderate and very high resolution satellite images were used to detect the presence and size of emperor penguin Aptenodytes forsteri colonies (Fretwell & Trathan 2009; Fretwell et al. 2012); very high resolution satellite images were also recently used to count southern right whales…”
