The Würm in NW Iberia, A pollen record from Area Longa (Galicia)
Abstract The pollen record at Area Longa is the westernmost sequence available for investigation of the last glaciation in continental Europe. It is located in a region, NW Iberia, for which data from times earlier than the late glacial period are scarce. It comprises a series of exposed limnetic le...
