Radiocarbon dates from Terra Nova Bay (Northern Victoria Land, Antarctica): conventional and calibrated ages.
A list of 106 14C dates obtained from samples collected in the area of Terra Nova Bay during the 1985/86, 1986/87, 1987/88 and 1988/89 field seasons of the "Programma Nazionale di Ricerche in Antartide" (ITALIANTARTIDE) is presented. All the samples but one are Holocene in age and consist...
