Regional comparison of the stratigraphic position of the Campanian Ignimbrite (solid black line) and the proposed environmental response linked to the Heinrich Event 4 (grey box) in the Mediterranean region. (a and b) The DSDDP lithological changes with reconstructed climatic conditions with the position of the CI isochrone and the accepted date of the CI; (c) Megali Limni pollen record31; (d) Tenaghi Philippon pollen record30; (e) Lago di Monticchio pollen record28,55; (f) The Black Sea Ca XRF-core-scanning record of the core M72/5-25-GC1 Ca-record21. Each record is plotted on their own individual timescale with the directly dated age of the CI given as 39.85 ± 0.14ka13 for the DSDDP record.
