Submillennial environmental fluctuations during marine Oxygen Isotope Stage 2: a comparative analysis of diatom and pollen evidence from Lago Grande di Monticchio, South Italy
High temporal resolution pollen and diatom analyses carried out on sediments from Lago Grande di Monticchio span the interval :23 700-21 200 calendar yr. BP, a brief interstadial during marine Oxygen Isotope Stage 2. Both records exhibit marked changes that are interpreted as responses to climatic c...
