In the frame of the ANtarctic DRILLing Program, volcanic glass fragments were collected from the AND-2A core between similar to 354 and 765 m below sea floor (mbsf) as accumulations (5-70 vol.%) within sediments. Here, we present the physical characteristics, age and geochemistry of the glass, which...
