Bathymetry Geological Setting of the South Sandwich Islands Volcanic Arc [Folded Map]

This sheet of the bathymetry and geological setting of the South Sandwich Islands and
the associated East Scotia Ridge back-arc spreading centre 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 forms a baseline for future glaciological changes caused by volcanic activities and
climate change. The back-arc spreading centre consists of nine segments, most of which
have rift-like morphologies. [Folded Map]
