Sediment core, taken with a gravity corer by the research vessel POLARSTERN in the South Atlantic; light/dark-coloured changes are due to climate cycles of the Quaternary; basis age of the core is about 1 Million years (length of each segment is 1 m). For a more detailed description and detail photographs of the core see Gersonde (2003).<sup id="cite_ref-gersonde_2003_1-0" class="reference"><a href="#cite_note-gersonde_2003-1">[1]</a></sup>
