The Antarctic Peninsula has experienced considerable anthropogenic warming in recent decades. While cryospheric responses are well defined, the responses of moss-dominated terrestrial ecosystems have not been quantified. Analysis of Landsat archives (1986–2021)…

As whales recover from commercial exploitation, they are increasing in abundance in habitats that they have been absent from for decades. However, studying the recovery and habitat use patterns of whales, particularly in remote and inaccessible regions…

Advances in remote sensing of emperor penguins: first multi-year time series documenting trends in the global population. Proceedings of the Royal Society B, 2024 (Ref: 17086)

LaRue M.Iles D.Labrousse S.Fretwell P.Ortega D.Devane E.Hortsmann I.Viollat L.Foster-Dyer R.Le Bohec C.Zitterbart D.Houstin A.Richter S.Winterl A.Wienecke B.Salas L.Nixon M.Barbraud C.Kooyman G.Ponganis P.Ainley D.Trathan P.Jenouvrier S.
Category 1: Peer-reviewed literature

Like many polar animals, emperor penguin populations are challenging to monitor because of the species' life history and remoteness. Consequently, it has been difficult to establish its global status, a subject important to resolve as polar environments change.

Category 1: Peer-reviewed literature

One of the key components of this research has been the mapping of Antarctic bed topography and ice thickness parameters that are crucial for modelling ice flow and hence for predicting future ice loss and the ensuing sea level rise. Supported by the Scientific Committee on Antarctic Research (SCAR)…
