Abstract
The content and distribution of Ge is investigated in sediments from the Southern Ocean (Prydz Bay, Antarctica). Thecontent of Getotal in the sediments ranges from 1.14×10 -6 to 2.35×10 -6 (average of 1.71×10 -6 ) and the highest value occurs at stationP3-9 where water depth is > 1 000 m. The lowest value occurs at station P4-13 which is near the edge of the Amery ice shelf. Thesurface sediments have 16%–68% Ge bio within Getotal. The distribution trends of Ge bio and Getotal are generally similar, and the valuesoutside Prydz Bay are higher than within the bay, bounded at 67°S. The vertical distribution of Ge in sediment cores presentshigher values at the surface than in underlying sediments. Values of Ge bio appear to positively correlate with biogenic silica (BSiO 2 )in surface sediments from non-polynyas sea. The vertical distribution of Ge bio and BSiO2 is similar in sediments of station P3-16.
