Palaeoenvironmental implications derived from a piston core from east lobe Bonney, Taylor Valley, Antarctica
A 270 cm long sediment sequence was recovered with a piston corer from east lobe Bonney Taylor Valley Antarctica and characterized according to its sedimentological mineralogical and geochemical properties It is the first record of such length recovered from east lobe Bonney The sediment core is mai...
