Rivera, A; Bravo, C. and G. Boub (2017) : "Climate Change and land ice" In: D. Richardson et al. (eds). The International Encyclopedia of Geography. Wiley, DOI: 10.1002/9781118786352.wbieg0538.

Glaciers provide excellent records of climate change. Samples of particulates and gases can be extracted from ice cores, from which the past composition of the atmosphere can be reconstructed. Ice cores also record temperature and moisture, and all of this information is stored in dateable, conse...


Stehlik M.; P. Aguirre; S. Girard; P. Jordanova; J. Kiselak; S. Torres; Z. Sadovsky and Rivera A. (2017) : "On ecosystems dynamics" Ecological complexity, 29: 10-29.

We show how a dynamical system given by a t-score function for some class of monotonic data transformations generates consistent extreme value estimators. The variation of their values increases the uncertainty of proper assessment of climate change. Two important examples illustrate the methodol...

This article reports the discovery of the subglacial Lake CECs (named in honor of the Centro de Estudios Científicos), located in the central part of the West Antarctic Ice Sheet (WAIS), on the ice divide between the Minnesota Glacier and the Institute Ice Stream. This lake, which was discovered...

Se presenta una actualización al año 2015 de las variaciones frontales de 5 glaciares que desprenden témpanos en las Torres del Paine de Chile y 2 en el Parque Nacional los Glaciares de Argentina, todos los cuales tienen un área combinada de 726.4 km². Estos glaciares han experimentado sin excepc...

In this work, we assessed the feasibility of using optical flow to obtain the motion estimation of a glacier. In general, former investigations used to detect glacier changes involve solutions that require repeated observations which are many times based on extensive field work. Taking into accou...


Rivera, A.; Bown, F.; Napoleoni, F.; C. Muñoz and Vuille, M. (2016) : "Balance de masa glaciar" Ediciones CECs, Valdivia, Chile, 203 pp.

La criósfera es la esfera o subsistema terrestre integrado por todas aquellas regiones de la Tierra y océano donde el agua se encuentra en forma sólida, incluyendo hielo marino, hielo en lagos, en ríos, superficies con nieve, glaciares, casquetes de hielo y permafrost. Estas formas de agua en...
