Resumen
A new record of last deglaciation in northeastern Spain is presented here based on the 18O variations from two stalagmites from Ostolo cave (W Pyrenees). The two stalagmites replicate very well the signal of abrupt changes that took place during the last deglaciation (18 – 10 ka BP) in synchrony with temperature changes in Greenland ice cores. A comparison with other nearby records (marine cores, lacustrine sediments and speleothems from northern Spain and southern France) allows discriminating different trends during last deglaciation indicating a high heterogeneity in the paleoenvironmental response to climate variability at this latitude
