A correlation is observed between changes in the level of Earth?s seismic activity and increments of the atmospheric methane concentration over the past 40 years. Trigger mechanisms are proposed for methane emissions and glacier collapse in polar regions...

In this work, we present the climatic evolution of the South Pacific Ocean from 1900 to 2010 and its environmental influence over West Antarctica. We analyzed the sea surface temperature, mean sea level pressure, and meridional wind (at 850 hPa) of the S...

Changes in macrobenthic and pelagic communities in the postglacial, partially isolated, lagoon Herve Cove in Admiralty Bay, King George Island, were investigated 15 years after the first comprehensive studies had been conducted in this region. The bottom...

Glacial forefields areas are dynamic landscapes, and due to the glacier frontal position changes, they are sensitive to climatic fluctuations. The results of the analysis of aerial photos, satellite imagery, archival maps, and terrestrial laser scanning ...

ABSTRACT. The batholiths of the Andean Cordillera in the Atacama and Coquimbo Regions (28-31°S) reflect tectonic processes associated with the evolving margin of the Gondwana supercontinent. The batholiths consist of the Carbonilerous-Lower Permian Elqui...
