Ecology and Biogeochemistry of the Southern Océan Project (subproject
Biogenic Sédimentation) of the Italian National Programme for Antarctic
Research (PNRA). The authors are indebted to E. Lipparini, A. Magagnoli and G.
Marozzi for gravity core and box core sampling. We are also grateful to E.
Lipparini for most of the 210Po extractions, G. Marozzi for X-radiography, and L.
Casoni and G. Zini for drawings. This is contribution No. 1155 from the Istituto di
Geologia Marina del CNR, Bologna.
