TL;DR: In this article, a new method for identifying rock exposures using Landsat 8 data is presented, which is the first automated methodology for snow and rock differentiation that excludes areas of snow (both illuminated and shaded), clouds and liquid water, achieving higher and more consistent accuracies than alternative data and methods such as NDSI.

TL;DR: In this article, the authors reviewed the allochthonous terrane accretion model for the geological development of the Antarctic Peninsula continental margin arc and reinterpreted the geology as having evolved as an in situ continental arc.

TL;DR: In this article, an updated kinematic reconstruction of the Scotia Sea region using the latest published marine magnetic anomaly constraints is presented, and place this in a South America-Africa-Antarctica plate circuit in which they take intracontinental deformation into account.

TL;DR: In this paper, the upper crust contributes up to 70% of the Antarctic Peninsula's subglacial heat flux and that heat flux values are more variable at smaller spatial resolutions than geophysical methods can resolve.

TL;DR: A review of the methods to estimate geothermal heat flow (GHF) can be found in this article, where the strengths and limitations of each approach are discussed, and a more accurate model of the structure and distribution of heat production elements within the crust and considering heterogeneities in the underlying mantle is proposed.
