Down‐core samples of planktonic and benthic foraminifera were analyzed for oxygen carbon isotopes in International Marine Past Global Changes Study (IMAGES) core MD99‐2343 order to study the interactions between climate change Northern Hemisphere western Mediterranean thermohaline circulation at times Heinrich events (HE). Our results confirm antiphase correlation enhanced North Atlantic Deep Water formation low ventilation Mediterranean. However, this reveals that relationship deepwater was...
The depositional history of the Storfjorden and Kveithola trough-mouth fans (TMFs) in northwestern Barents Sea has been investigated within two coordinated Spanish Italian projects framework International Polar Year (IPY) Activity 367, NICE STREAMS. investigation conducted using a multidisciplinary approach to study sediment cores positioned on high-resolution multibeam bathymetry TOPAS/CHIRP sub-bottom profiles. Core correlation age model were based 27 AMS 14C samples, rock magnetic...
We examined the total diatom flux and species composition, coccolith mass collected with a sediment trap between October 1993 January 2006 in northeastern entrance of Gulf Lions (North Western Mediterranean). The average daily fluxes (3 × 107 valves m2 d–1 6.1 108 coccoliths day−1, respectively) are comparable magnitude previously reported data sets other high productivity areas Mediterranean. temporal particle pattern reflected variations surface oceanographic conditions primary...
Two gravity cores, Gebra-1 and Gebra-2 from the central eastern basins of Bransfield Strait, West Antarctica, consist mainly hemipelagic, laminated muds with black layers rich in sand-sized volcanic ash. Micropalaeontological (diatoms radiolarians) geochemical (organic inorganic) analyses, together radiometric dating (U/Th, 14 C 210 Pb) have been performed on both cores. AMS analyses Total Organic Carbon yielded a C-age older than expected, 2810 yr BP for core top 2596 Gebra-2. The downcore...
Abstract The hydrography of the Indian‐Atlantic Ocean gateway has been connected to high‐latitude climate dynamics by oceanic and atmospheric teleconnections on orbital suborbital timescales. A wealth sedimentary records aiming at reconstructing late Pleistocene paleoceanography around southern African continent devoted understanding these linkages. Most are, however, clustered close South tip, with comparatively less attention areas under direct influence frontal zones Southern Ocean/South...
The Antarctic Peninsula is sensitive to climatic change due its northerly position and the relatively reduced volume character of ice cover. High-resolution palaeoclimatic records from Ant arctic cores extend back only 500 years. A record 2850 years in Bransfield Basin investigated through analysis sediment gravity floor central subbasin (core GEBRA-1) slope eastern GEBRA-2). Sedimentological, mineralogical geo chemical properties have been systematically measured, together with Accelerator...
