Revealing climatic variability of the last three millennia in northwestern Iberia using pollen influx data
Climatic variability of the last 3 millennia in NW Iberia has been documented using high-resolution pollen analysis of Vir-18 core. retrieved from the Ria de Vigo (42degrees14.07'N, 8degrees47.37'W). The depth-age model is based on two accelerator mass spectrometry C-14 dates and three his...

Climatic variability of the last 3 millennia in NW Iberia has been documented using high-resolution pollen analysis of Vir-18 core. retrieved from the Ria de Vigo (42degrees14.07'N, 8degrees47.37'W).
