Seismic Profiles from Port Foster, Deception Island (Antarctica)

Deception Island (South Shetland Islands, Antarctica) consist of a horseshoe-shaped volcanic edifice, which evolution is marked by the formation of a collapse caldera. It is the most active volcano in the South Shetland archipelago with more than 20 eruptions in the past two centuries. In order to improve our knowledge about Deception Island, a total of 12 parametric seismic profiles were obtained from the island’s interior bay (Port Foster) during the 2017/2018 Spanish Antarctic Campaign and the Antarctic GALILEO-IHM cruise aboard the R/V Hespérides (2017 / 2018) with a hull-mounted TOPAS PS 018 high-resolution parametric sounder designed for sub-bottom profiling with very high spatial resolution in water depths from less than 20 meters to full ocean depth.
