Objectif
IT IS PROPOSED TO STUDY THE CLIMATIC HISTORY OF WESTERN EUROPE IN THE LAST 15000 YEARS USING THE TECHNIQUE OF POLLEN ANALYSIS ON A CONTINENTAL SCALE ON SMALL LAKE SITES IN TWO TRANSECTS FROM IRELAND AND BRITAIN (1) ALONG THE COAST OF WESTERN EUROPE AND (2) TO THE MEDITERRANEAN REGION IN ITALY. THE POLLEN DATA WILL BE TRANSFORMED INTO QUANTITATIVE CLIMATIC INFORMATION USING TRANSFER FUNCTIONS.
EXTENSIVE USE WILL BE MADE OF COMPUTER TECHNIQUES FOR DATA ANALYSIS. SPECIAL IMPORTANCE IS ATTACHED TO INVESTIGATING THE LINKS BETWEEN MARINE AND TERRESTRIAL CLIMATIC EVENTS, ESPECIALLY TO PROVIDE FOR THE FIRST TIME QUANTITATIVE ESTIMATES OF PAST TEMPERATURE AND PRECIPITATION FOR THE LAST 14000 YEARS ALONG TRANSECTS FROM SOUTHERN SPAIN TO WESTERN LAND AND FROM EASTERN ENGLAND TO NORTHERN ITALY BY MEANS OF POLLEN ANALYSIS. MODERN POLLEN-CLIMATE TRANSFER FUNCTIONS WILL BE USED TO TRANSFORM FOSSIL POLLEN DATA INTO QUANTITATIVE CLIMATIC ESTIMATES IN ORDER:
TO STUDY THE TIMING AND MAGNITUDE OF CLIMATIC CHANGE DURING THE LATE-GLACIAL AND HALOCENE AND TO COMPARE SUCH CHANGES WITH EVENTS IN THE NORTH ATLANTIC.
TO PROVIDE LINKS BETWEEN THE MARINE AND TERRESTRIAL RECORDS OF PAST CLIMATE.
TO STUDY LAGS AND LEADS IN BIOLOGICAL RESPONSE TO CLIMATE CHANGE IN TERRESTRIAL ECOSYSTEMS.
