Abstract:
The following database results from the campaign 7817857/OF/AvH_Normandy; label event NORM-2023. Observations have been made on the oxygen and carbon isotopic composition of specimens of Lenticulina in order to understand variations in nutrient origin and temperature at the water-sediment interface. Methodology includes the analysis of stable carbon and oxygen isotopes, measured using a ThermoFisher MAT 253 plus mass spectrometer coupled on-line to a Kiel IV device for automated CO2 preparation at Heidelberg University. The long-term reproducibility of the in-house working standard (Solnhofen limestone) during the analysis window was 0.02‰ and 0.06‰ for the carbon and oxygen isotopes, respectively. The analysed material has been derived from 19 samples and a total of 127 specimens of the most frequently encountered calcareous benthic foraminifers, collected in the discontinuous cliffs that run northwards from Le Havre, towards Cauville in Normandy, NW France. The following sections are studied: Cap de la Hève Section (HE) 49.5119,0.0672, 2M; Saint Andrieux Section (SA) 49.5414,0.0841, 1M ; and Tronquay Section (TR) 49.5350,0.0810 1M.
