“…During the last decade a considerable amount of soil, permafrost and geomorphological studies have been carried out in this region which is becoming warmer and wetter (Michel et al, 2006(Michel et al, , 2012(Michel et al, , 2014Navas et al, 2006Navas et al, , 2008Simas et al, 2006Simas et al, , 2007Simas et al, , 2008Schaefer et al, 2007;Serrano et al, 2008;Vieira et al, 2008Vieira et al, , 2010Vieira et al, , 2014Francelino et al, 2011;López-Martínez et al, 2012;Moura et al, 2012;Balks et al, 2013;Bockheim et al, 2013;Oliva and Ruiz-Fernández, 2015;Simas et al, 2015;Oliva et al, 2016).

“…Soils in the South Shetland Islands show differences with those of Antarctic continental regions as a consequence of different climatic conditions that determine edaphic processes and soil development (Balks et al, 2013). Relationships between soils and geomorphology have also been shown throughout the South Shetland Islands (Michel et al, 2014).

“…Faunal activity plays a marked role in soil genesis on Fildes Peninsula and is commonly found in the north shore of the peninsula. The dominant soils are Cryosols, related to cryoturbation and active-layer processes and developed on wide areas occupied by stone fields, patterned grounds, moraines and slopes on middle and upper platforms and hills in the northern and southern areas (Michel et al, 2014).…”

Abstract. International attention to climate change phenomena has grown in the last decade; the active layer and permafrost are of great importance in understanding processes and future trends due to their role in energy flux regulation. The objective of this paper is to present active-layer temperature data for one Circumpolar Active Layer Monitoring South hemisphere (CALM-S) site located on the Fildes Peninsula, King George Island, maritime Antarctica over an 57-month period (2008-2012). The monitoring site was installed during the summer of 2008 and consists of thermistors (accuracy of ±0.2 • C), arranged vertically with probes at different depths, recording data at hourly intervals in a highcapacity data logger. A series of statistical analyses was performed to describe the soil temperature time series, including a linear fit in order to identify global trends, and a series of autoregressive integrated moving average (ARIMA) models was tested in order to define the best fit for the data. The affects of weather on the thermal regime of the active layer have been identified, providing insights into the influence of climate change on permafrost. The active-layer thermal regime in the studied period was typical of periglacial environments, with extreme variation in surface during the summer resulting in frequent freeze and thaw cycles. The active-layer thickness (ALT) over the studied period shows a degree of variability related to different annual weather conditions, reaching a maximum of 117.5 cm in 2009. The ARIMA model could describe the data adequately and is an important tool for more conclusive analysis and predictions when longer data sets are available. Despite the variability when comparing temperature readings and ACT over the studied period, no trend can be identified.

“…A maior diversidade de processos repercute numa variedade de tipos de solos, com destaque para aqueles associados à dinamica do permafrost, os solos ornitogênicos e os solos sulfatados (FRANCELINO et al, 2011;MICHEL et al, 2014).…”
