Article
Internal water in cold‐water and tropical coral skeletons was extracted and measured for its oxygen and hydrogen isotope ratios. Water was extracted by crushing pieces of coral hard tissue in a percussion device connected to either a cavity‐ring down spectroscopy (CRDS) system or an isotope ratio mass spectrometry (IRMS) system. Despite most sample...

This study provides a detailed reconstruction of cold-water coral mound build-up within the East Melilla Coral Province (Southeast Alboran Sea) over the last 300 ky. Based on benthic foraminiferal assemblages, macrofaunal quantification, grain size analysis, sediment geochemistry, and foraminiferal stable isotope compositions, a reconstruction of e...

This study provides a detailed reconstruction of climatic events affecting a cold-water coral mound located within the East Melilla Coral Province (Southeast Alboran Sea) over the last 300 ky. Based on benthic foraminiferal assemblages, macrofaunal quantification, grain size analysis, sediment geochemistry, and foraminiferal stable isotope composit...

The Alboran Sea is widely recognized to host numerous cold-water coral ecosystems, including the East Melilla Coral Province. Yet, their development through time and response to climatic variability has still to be fully understood. Based on a combined investigation of benthic foraminiferal assemblages, foraminiferal stable isotope compositions, gr...
Article
Full-text available
Cold‐water coral (CWC) mounds are build‐ups comprised of coral‐dominated intervals alternating with a mixed carbonate‐siliciclastic matrix. At some locations, CWC mounds are influenced by methane seepage, but the impact of methane on CWC mounds is poorly understood. To constrain the potential impact of methane on CWC mound growth, lipid biomarker i...
Thesis
The aim of this thesis is to contribute to the understanding of the impact of early diagenesis on cold-water coral (CWC) mound fabrics and carbonate preservation pathways in discrete mound structures. Studying diagenetic patterns in mound sediments is important to understand better the intrinsic controls on CWC mound formation through time, and its...

Project
The 4D-DIAGENESIS@MOUND project aims to decipher the temporal and spatial variability of diagenesis in carbonate mounds influenced by a shallow sulphate-methane transition zone (SMTZ). In first instance the spatial variation will be deciphered through the detailed study of gravity cores taken along a core transect on one specific carbonate mound on Pen Duick Escarpment in the Gulf of Cadiz. Additional core sections on the top of carbonate mounds in the Melilla Mound Field in the Alboran Sea will be targeted for the quantification of diagenetic imprints (especially coral dissolution and authigenic microbial-induced carbonate precipitation). The cores will become available within the framework of the EuroFLEETS campaign ‘The Mediterranean-Atlantic Gateway Code: The Late Pleistocene Carbonate Mound Record’ which will take place in June 2013 aboard the R/V Marion Dufresne. During a second phase of the project, carbonate mound sediments will be brought within a bioreactor to monitor dissolution and precipitation of mineral phases through time under constrained lab-conditions. Special attention will be paid to the development of an in-house bioreactor simulating the environment wherein carbonate mound systems thrive, as well as to the 3D visualization of the diagenetic phases within mound sediments by means of multi-scaled nanotomography.
