Analysis of a sediment core MVSEIS08_TG-2 taken during the MVSEIS2008 expedition in Gulf of Cadiz

Description
Summary:Core MVSEIS08-TG-2 was acquired during the Euromargin-MVSEIS08 cruise on the Moroccan margin, south of the Gulf of Cadiz. This site was targeted to discuss the possibility of the saline upper branch of the Mediterranean Outflow Water (MOW) diverging southwards along the Moroccan margin, in addition to the well-established northern MOW current. The southern TG-2 is a 2.12 m gravity core. Contourite records cover the time interval from the last deglaciation starting at HS1 (18.6 ka) to the Holocene. New datasets of current velocity (sortable silt) and water mass origin (O and C isotopes of benthic foraminifera) define the intensity of the MOW as contourite deposits, together with element ratios (XRF-scan) and physical properties of the sediment. O and C isotopes of planktonic foraminifera, foraminiferal species and sea surface temperature (simmax.28 transfer function) were used to determine millennial climate changes during the last deglaciation.
