Description
Summary:The South Sandwich Islands and associated seamounts constitute the volcanic arc of an active subduction system situated in the South Atlantic. We introduce a map of the bathymetry and geological setting of the South Sandwich Islands and the associated East Scotia Ridge back-arc spreading centre that consists of two sides: side 1, a regional overview of the volcanic arc, trench and back-arc, and side 2, detailed maps of the individual islands. Side 1 displays the bathymetry at scale 1:750 000 of the intra-oceanic, largely submarine South Sandwich arc, the back-arc system and other tectonic boundaries of the subduction system. Satellite images of the islands on side 2 are at scales of 1:50 000 and 1:25 000 with contours and main volcanological features indicated. These maps are the first detailed topological and bathymetric maps of the area. The islands are entirely volcanic in origin, and most have been volcanically or fumarolically active in historic times. Many of the islands are ice-covered, and the map ... : AWI = Alfred Wegner Institute, BAS = British Antarctic Survey, LDEO = Lamont Doherty Earth Observatory, MARUM = Center for Marine Environmental Sciences, University of Bremen, MBES = multibeam echo sounder,MGDS = Marine Geoscience Data System, HAWAII MR1 = HIG, Hawaii Institute of Geophysics and Planetology Acoustic Wide Angle Imaging Instrument Mapping Researcher 1, SBES = singlebeam echo sounder, SHN = Servicio de Hidrografia Naval, WHOI = Woods Hole Oceanographic Institution. ...
