HOLOCENE CLIMATIC OSCILLATIONS IN JURA ALPS - OCEANIC AND SOLAR FORCING

The recent extension of the residual DELTAC-14 curve back to 12,000 ca l. BP (Stuiver et al., 1993) offers the opportunity to test by proxy d ata the relationships between climate, atmospheric C-14, sun and ocean as discussed by Stuiver and Braziunas (1993). Tentative correlations between the C-14 and palaeoclimatic records from the Jura and Alps reg ions would suggest an interesting working hypothesis. Two periods coul d be distinguished in the middle latitudes of Western and Central Euro pe: an early Holocene period with abrupt climatic oscillations linked to ocean forcing and, after 6,000 cal. BC, a second Holocene period wi th smoother climatic oscillations linked to solar forcing.
