Five cores from the southern Tyrrhenian and Ionian seas were studied for their tephra and cryptotephra content in the 4.4–2.0 ka time interval. The chronological framework for each core was obtained by accelerator mass spectrometry14C dating, the o

Paleostudies often rely on foraminiferal calcite chemistry, which reflect past sea water condition through so-called proxy relationships. One way to evaluate robustness of these proxy relationships is to test them in well-studied and during well-cons

The trace-metal composition of sediments provides important information on (past) environmental conditions, such as bottom water oxygenation, marine productivity, sediment provenance, and pollution. Whereas major and minor elements are often routinel

Eastern-Mediterranean ventilation variability during sapropel S1 formation, evaluated at two sites influenced by deep-water formation from Adriatic and Aegean Seas

Autor: Filippidi, A., Triantaphyllou, M.V., De Lange, G.J., Geochemistry, Marine geochemistry & chemical oceanography

Publikováno v: Quaternary Science Reviews, 144, 95. Elsevier Limited

Present-day bottom-water ventilation in the Eastern Mediterranean basin occurs through deep-water convection originating from the two marginal basins, i.e. Adriatic and Aegean Seas. In the paleo record, long periods of enhanced deep-water formation h

Manganese geochemistry in deep-sea sediments is known to vary greatly over the first few centimeters, which overlaps the in-sediment depth habitats of several benthic foraminiferal species. Here we investigated manganese incorporation in benthic fora

Publikováno v: Utrecht Studies in Earth Sciences, 169. UU Dept. of Earth Sciences

Fossil remnants of benthic foraminifera consist of carbonate tests and their organic linings. The macromolecular and stable isotopic composition of these benthic foraminiferal organic linings was characterized to evaluate their potential use as paleo

Biogenic fluxes from two sediment traps in the Ionian sea (35°13'N, 21°30'E) at 500 and 2800 m water depth are discussed in relation with the main oceanographic and external forcing and compared with previous data from a nearby location. This study
