Atmosphere-ocean-ice interactions in the Amundsen Sea Embayment, West Antarctica
Read more of: Atmosphere-ocean-ice interactions in the Amundsen Sea Embayment, West AntarcticaOver recent decades outlet glaciers of the Amundsen Sea Embayment (ASE), West Antarctica, have accelerated, thinned and retreated, and are now contributing approximately 10% to global sea level rise. All […]

The spatial distribution of Antarctica’s protected areas: a product of pragmatism, geopolitics, or conservation need?
Read more of: The spatial distribution of Antarctica’s protected areas: a product of pragmatism, geopolitics, or conservation need?Globally, few protected areas exist in areas beyond the jurisdiction of a single state. However, for over 50 years the Antarctic protected areas system has operated in a region governed […]

Freshwater diatom biogeography and the genus Luticola: an extreme case of endemism in Antarctica
Read more of: Freshwater diatom biogeography and the genus Luticola: an extreme case of endemism in AntarcticaHistorical views have characterized Antarctica as a frozen desert with low diversity, although recent studies suggest that this may not be true for microscopic organisms. For microbes, assessing endemism in […]
