Objectif THIS PROJECT WILL BE CONCERNED WITH THE PATTERN AND INCIDENCE OF STORM SURGES IN THE NORTH SEA BASIN DURING THE HOLOCENE. THE MAIN AREAS TO BE EXAMINED WILL BE THE EASTERN COASTS OF SCOTLAND AND ENGLAND AND THE NORTH SEA COAST OF THE FEDERAL REPUBLIC OF GERMANY. BOTH HISTORICAL AND GEOLOGICAL EVIDENCE FOR THESE STORM SURGES HAS ALREADY BEEN IDENTIFIED IN PARTS OF THESE AREAS. THE FIRST PHASE OF THIS WORK WILL INVOLVE FIELD RESEARCH. VERY DETAILED STRATIGRAPHICAL STUDIES WILL BE CARRIED OUT AND ALL BOREHOLES AND SECTIONS WILL BE LEVELLED TO LOCAL DATUMS. FIELDS MAPS AT SCALES OF 1 : 10000 OR BETTER WILL BE MADE OF EACH LOCATION. CRITICAL STRATIGRAPHIES WILL BE SAMPLED USING CORERS AND THE CORES RETRIEVED FOR TRANSPORT BACK TO THE LABORATORY. AT INTERVALLS DURING THIS PHASE SOME STUDY OF HISTORICAL RECORDS WILL BE UNDERTAKEN WHEN THE OPPORTUNITY ALLOWS. DURING THE SECOND PHASE LABORATORY STUDY OF THE CORES RETRIEVED WILL BE UNDERTAKEN. VERY DETAILED POLLEN ANALYSES, INVOLVING SAMPLING AT CLOSE VERTICAL INTERVALLS, PERHAPS AS CLOSE AS 1 CM, WILL BE UNDERTAKEN TO IDENTIFY CHANGES IN THE LOCAL VEGETATION PATTERN, NOTABLY PERIODS OF MARINE INFLUENCE. DURING THIS PHASE ALSO, STUDIES OF DIATOMS WILL BE MADE, NOT ONLY TO DETERMINE PERIODS OF MARINE INFLUENCE, BUT ALSO TO IDENTIFY PERIODS OF STORMINESS, SINCE IT IS KNOWN THAT IN MANY LOCALITIES DIATOMS MAY REFLECT THESE. SOME STUDIES OF FORAMINIFERA AND OSTRACODS MAY BE UNDERTAKEN AT THIS TIME. IN ADDITION STUDIES OF THE GEOCHEMISTRY OF THE MINEROGENIC SEDIMENTS IN THE CORES WILL BE UNDERTAKEN TO HELP DETERMINE THE SOURCES OF THE SEDIMENTS. AT THIS STAGE TOO, SAMPLES FOR RADIO-CARBON ASSAY WILL BE UNDERTAKEN FROM BIOGENIC HORIZONS IN THE CORES TO DETERMINE THE AGE OF THE SEDIMENTS CONTAINING STORM SURGE EVIDENCE. THESE SAMPLES WILL PROVIDE A TIME-STRATIGRAPHIC FRAMEWORK, WHICH WILL HELP DETERMINE THE FREQUENCY OF EVENTS AND THE AGE OF SOME INDIVIDUAL EVENTS. FURTHER SURVEY OF HISTORICAL DATA WILL CONTINUE DURING THIS PHASE.
