AbstractDeception Island (South Shetland Islands) is one of the most active volcanoes in Antarctica, with more than 15 explosive eruptive events registered over the past two centuries. Recent eruptions (1967, 1969 and 1970) and volcanic unrest episodes in 1992, 1999 and 2014–15 demonstrate that the occurrence of future volcanic activity is a valid and pressing concern for scientists, logistic personnel and tourists that are visiting or are working on or near the island. Over the last few decades, intense research activity has been carried out on Deception Island to decipher the origin and evolution of this very complex volcano. To that end, a solid integration of related scientific disciplines, such as tectonics, petrology, geochemistry, geophysics, geomorphology, remote sensing, glaciology, is required. A proper understanding of the island's evolution in the past, and its present state, is essential for improving the efficiency in interpreting monitoring data recorded during volcanic unrest periods and, hence, for future eruption forecasting. In this chapter, we briefly present Deception Island's most relevant tectonic, geomorphological, volcanological and magmatic features, as well as the results obtained from decades of monitoring the island's seismic activity and ground deformation.

Antarctica was the last continent to be known. Human encounters with the region acquired different characteristics over time. Within the framework of dominant narratives, the early ‘exploitation’ of the territory was given less attention than late nineteenth- and early twentieth-century ‘exploration’. Nineteenth-century exploitation was especially associated with sealing on the South Shetland Islands. Dominant narratives on the period refer to the captains of sealing vessels, the discovery of geographical features, the volume of resources obtained. However, they do not consider the life of the ordinary sealers who lived and worked on the islands. This chapter aims to show the power of archaeology to shed light on these ‘invisible people’ and their forgotten stories. It holds that archaeology offers a possibility for reimagining the past of Antarctica, calling for a revision of traditional narratives.

This research is part of the results of the three first expeditions of Colombia to West Antarctica and it focused on the systematics and taxonomic diversity of the benthic community of molluscs collected between 5 and 400 m deep. The Sampling sites where mollusks were collected were located along the Gerlache and Bransfield straits, around the Palmer Archipelago and the South Shetland Islands, adjacent to the Antarctic Peninsula. The list of identified species that are deposited in the Museum of Marine Natural History of Colombia - Makuriwa, of the Institute of Marine and Coastal Research “José Benito Vives de Andréis” -Invemar, is presented. This inventory consisted of 15 specimens distributed in 10 taxa, of which 7 were shelled gastropods (including 5 microgastropods) and 3 were bivalves. Four microgastropods were placed in greater taxonomic categories due to the low knowledge of these taxa in the region (Anatoma sp., Cingulopsoidea sp., Truncatelloidea sp. and Eatoniella sp.). The other gastropod species (3) were Margarella antarctica, Prosipho turritus and Nacella concinna. The bivalves found were Philobrya sublaevis, Adacnarca nitens and Thracia meridionalis. The identified species have previously been recorded in West Antarctica. Some of them, like the bivalves, show a circumantarctic distribution. Nacella concinna was the most abundant taxon. In coherence with the general objective of the “BioGerlache-Antarctica” project, the results generate contributions to the biological inventories of Antarctica, contributing to expand the information to define possible conservation areas in the future.
